很久没有更新博客了，本想着直接发一篇《手撕ERP》系列，从控件重写、重绘，到框架搭建，再到部分模块实现+业务的。但是每次动手的时候，都觉得难以下手。直接从数据库设计开始吧，模块设计还没定下来，从模块设计开始吧，winform自带控件和DevExpress控件用起来布局实在太难看了。算了，从低做起吧。接着6-7年前的玩转控件系列开始，工欲善其事必先利其器！利器备好，框架搭建完毕，模块设计就是拖控件而已！Talk is Cheap,Show me the Code!        首先，项目中新建一个窗体(用于后面的弹窗载体)，按自己意愿做好布局效果，当然关于皮肤方面，大家可以应用界内很成熟的皮肤控件(具体就不列举了，避免打广告的嫌疑)，或者后期自己代码实现。本篇主要介绍如何重写/重绘控件，磨自己的利器，至于利器上贴个动漫图片还是其他花里胡哨的图案，请根据自己的喜好来。大概效果如图(有洁癖的请自己细心布局)：

窗体后台代码分析如下：首先窗体集成DevExpress：

 public partial class frm_MessageBox : DevExpress.XtraEditors.XtraForm

其余初始化动作代码如下，备注很详细就不一一列举了：

 /// /// 确定按钮/// private SimpleButton btn_OK;/// /// 取消按钮/// private SimpleButton btn_Cancel;/// /// 中止按钮/// private SimpleButton btn_Abort;/// /// 重试按钮/// private SimpleButton btn_Retry;/// /// 忽略按钮/// private SimpleButton btn_Ignore;/// /// 是按钮/// private SimpleButton btn_Yes;/// /// 否按钮/// private SimpleButton btn_No;/// /// 要在消息框中显示的文本/// private string text;/// /// 要在消息框的标题栏中显示的文本/// private string caption;/// ///  System.Windows.Forms.MessageBoxButtons 值之一，可指定在消息框中显示哪些按钮/// private MessageBoxButtons buttons;/// /// System.Windows.Forms.MessageBoxIcon 值之一，它指定在消息框中显示哪个图标/// private MessageBoxIcon icon;/// /// System.Windows.Forms.MessageBoxDefaultButton 值之一，可指定消息框中的默认按钮。/// private MessageBoxDefaultButton defaultButton;/// /// 消息弹出框参数实体/// MessageBoxModel _MessageBoxModel = default(MessageBoxModel);

界面初始化：

/// /// 支持修改弹出框的按钮标题描述/// /// public frm_MessageBox(MessageBoxModel pMessageBoxModel){    InitializeComponent();    if (pMessageBoxModel == null)        pMessageBoxModel = new MessageBoxModel();    this.ControlBox = false;    this.text = pMessageBoxModel.MsgText;    this.Text = pMessageBoxModel.FormText ?? "Stephen's UserControl";    this.caption = pMessageBoxModel.FormText;    this.buttons = pMessageBoxModel.MsgButton;    this.icon = pMessageBoxModel.MsgIcon;    this.defaultButton = pMessageBoxModel.MsgxDefaultButton;    this._MessageBoxModel = pMessageBoxModel;}/// /// 显示一个具有指定文本、标题、按钮、图标、默认按钮的消息框/// /// /// /// /// /// public frm_MessageBox(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton){    InitializeComponent();    this.ControlBox = false;    this.text = text;    this.Text = caption ?? "Stephen's UserControl";    this.caption = caption;    this.buttons = buttons;    this.icon = icon;    this.defaultButton = defaultButton;}

窗体Load事件绑定弹窗按钮事件：

private void frm_MessageBox_Load(object sender, EventArgs e){    int pannelLength = panelButton.Size.Width;    switch (buttons)    {        case MessageBoxButtons.OK:            #region OK            this.btn_OK = new SimpleButton();

代码比较简单，就是把初始化按钮事件和把初始化的弹窗中的按钮添加到布局中的Panel容器里面和一些细节调整，关于方法sysClass.ssLoadMsgOrDefault目前可以不用在意，是我的通用类库，主要是用来实现国际化的，后续会断断续续为大家介绍这块代码。按钮绑定事件和键盘响应事件代码如下：

private void PaintIcon(Icon icon, int x, int y)  {      Graphics g = this.CreateGraphics();      g.DrawIcon(icon, x, y);  }  void btn_No_Click(object sender, EventArgs e)  {      this.DialogResult = DialogResult.No;  }  void btn_Yes_Click(object sender, EventArgs e)  {      this.DialogResult = DialogResult.Yes;  }  void btn_Ignore_Click(object sender, EventArgs e)  {      this.DialogResult = DialogResult.Ignore;  }  void btn_Retry_Click(object sender, EventArgs e)  {      this.DialogResult = DialogResult.Retry;  }  void btn_Abort_Click(object sender, EventArgs e)  {      this.DialogResult = DialogResult.Abort;  }  void btn_Cancel_Click(object sender, EventArgs e)  {      this.DialogResult = DialogResult.Cancel;  }  void btn_OK_Click(object sender, EventArgs e)  {      this.DialogResult = DialogResult.OK;  }  private void frm_MessageBox_KeyUp(object sender, KeyEventArgs e)  {      if (e.Modifiers == Keys.None)      {          if (e.KeyCode == Keys.O && btn_OK != null)          {              btn_OK_Click(null, null);          }          if (e.KeyCode == Keys.C && btn_Cancel != null)          {              btn_Cancel_Click(null, null);          }          if (e.KeyCode == Keys.A && btn_Abort != null)          {              btn_Abort_Click(null, null);          }          if (e.KeyCode == Keys.R && btn_Retry != null)          {              btn_Retry_Click(null, null);          }          if (e.KeyCode == Keys.I && btn_Ignore != null)          {              btn_Ignore_Click(null, null);          }          if (e.KeyCode == Keys.Y && btn_Yes != null)          {              btn_Yes_Click(null, null);          }          if (e.KeyCode == Keys.N && btn_No != null)          {              btn_No_Click(null, null);          }      }      if (e.Modifiers == Keys.Control && e.KeyCode == Keys.C)      {          string mCopyText = "-------------------------------";          mCopyText += "\n";          mCopyText += lblMsg.Text + "\n";          mCopyText += "-------------------------------";          Clipboard.SetText(mCopyText);      }  }  private void frm_MessageBox_Paint(object sender, PaintEventArgs e)  {      Icon msgIcon;      switch (icon)      {          case MessageBoxIcon.Error:              msgIcon = System.Drawing.SystemIcons.Error;              break;          case MessageBoxIcon.Question:              msgIcon = System.Drawing.SystemIcons.Question;              break;          case MessageBoxIcon.Exclamation:              msgIcon = System.Drawing.SystemIcons.Exclamation;              break;          default:              msgIcon = System.Drawing.SystemIcons.Information;              break;      }      e.Graphics.DrawIcon(msgIcon, 40, 20);  }}

以及弹窗实体类：

 /// /// 弹出框实体/// public class MessageBoxModel{    ///     /// 弹出框标题    ///     public string FormText { get; set; }    ///     /// 弹出框宽度    ///     public int FormWidth { get; set; }    ///     /// 弹出框高度    ///     public int FormHeight { get; set; }    ///     /// 弹出框消息内容    ///     public string MsgText { get; set; }    ///     /// 文字大小    ///     public int FontSize { get; set; }    ///     /// “是”按钮标题    ///     public string YesButtonText { get; set; }    ///     /// “否”按钮标题    ///     public string NoButtonText { get; set; }    ///     /// “取消”按钮标题    ///     public string CancleButtonText { get; set; }    ///     /// 弹出框类型(提示型、选择型等)    ///     public MessageBoxButtons MsgButton = MessageBoxButtons.OK;    ///     /// 弹出框中显示的图标    ///     public MessageBoxIcon MsgIcon = MessageBoxIcon.Information;    ///     /// 弹出框默认选中的按钮    ///     public MessageBoxDefaultButton MsgxDefaultButton = MessageBoxDefaultButton.Button1;

细心的读者会发现，博主在实例弹窗实体的时候，有个语法糖：

    ///     /// 消息弹出框参数实体    ///     MessageBoxModel _MessageBoxModel = default(MessageBoxModel);

default(T) 这是C# 7.1的关键字新用法，主要用法是默认值表达式，default对应各种类型生成默认值列表如下：

类型	默认值
任何引用类型	null
数值类型	0
bool	false
enum	表达式(E)0生成的值，其中E是枚举标识符
struct	通过如下设置生成的值：将所有值类型的字段设置为其默认值，将所有引用类型的字段设置为null    ‍
可以为null的类型	HasValue属性为false且Value属性未定义的实例

罗列一下上述列表中常见类型对应的值

default(string) // nulldefault(int) // 0default(int?) // nulldefault(dynamic) // nulldefault(DateTime) // 0001/01/01 0:00:00default(DateTime?) // null

好了，篇幅有限，具体深入了解请大家自行百度看看微软文档的解释。以上是窗体代码解析，窗体创建好了，最后一步，创建一个实体类(暂时命名KzxMessageBox)用来调用弹窗的窗体显示，具体代码如下：

public class KzxMessageBox{    ///     /// 标题     ///     private static string caption;    ///     /// 按钮(默认“OK”)    ///     private static MessageBoxButtons buttons;    ///     /// 图标(默认“information”)    ///     private static MessageBoxIcon icon;    ///     /// 默认按钮(默认“button1”)    ///     private static MessageBoxDefaultButton defaultButton;    ///     /// 静态构造函数，初始化数据    ///     static KzxMessageBox()    {        if (SysVar.loginType == 1)        {            caption = "Stephen's UserControl";        }        else        {            caption = sysClass.ssLoadMsgOrDefault("SYS000008", "Stephen's UserControl");        }        buttons = MessageBoxButtons.OK;        icon = MessageBoxIcon.Information;        defaultButton = MessageBoxDefaultButton.Button1;    }    ///     /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框    ///     /// 文本    ///     public static DialogResult Show(string text)    {        return Show(text, buttons, icon, defaultButton, null);    }    ///     /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框，add by zhang.jz 2019.05.10    ///     /// 文本    ///     public static DialogResult Show(string text, int pFormWidth = 0, int pFormHeight = 0)    {        return Show(text, buttons, icon, defaultButton, null, pFormWidth, pFormHeight);    }    ///     /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框    ///     ///     ///     ///     public static DialogResult Show(string text, Form parent)    {        return Show(text, buttons, icon, defaultButton, parent);    }    ///     /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框    ///     /// 文本    /// 按钮    ///     public static DialogResult Show(string text, MessageBoxButtons buttons)    {        return Show(text, buttons, icon, defaultButton, null);    }    ///     /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框    ///     ///     ///     ///     ///     public static DialogResult Show(string text, MessageBoxButtons buttons, Form parent)    {        return Show(text, buttons, icon, defaultButton, parent);    }    ///     /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框    ///     /// 文本    /// 标题    /// 按钮    /// 图标    ///     public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon)    {        return Show(text, buttons, icon, defaultButton, null);    }    ///     /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框    ///     ///     ///     ///     ///     ///     public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon, Form parent)    {        return Show(text, buttons, icon, defaultButton, parent);    }    ///     /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框    ///     ///     ///     ///     ///     ///     public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton)    {        return Show(text, buttons, icon, defaultButton, null);    }    ///     /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框    ///     /// 文本    /// 标题    /// 按钮    /// 图标    /// 默认按钮    /// System.Windows.Forms.DialogResult 值之一    public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, Form parent, int pFormWidth = 0, int pFormHeight = 0)    {        using (frm_MessageBox frm = new frm_MessageBox(text, caption, buttons, icon, defaultButton))        {            if (parent == null || parent.IsDisposed)            {                frm.StartPosition = FormStartPosition.CenterScreen;                 if (pFormWidth != 0) frm.Width = pFormWidth;                if (pFormHeight != 0) frm.Height = pFormHeight;                return frm.ShowDialog();            }            else            {                frm.StartPosition = FormStartPosition.CenterParent;                 if (pFormWidth != 0) frm.Width = pFormWidth;                if (pFormHeight != 0) frm.Height = pFormHeight;                return frm.ShowDialog(parent);            }        }    }    public static DialogResult Show(Form parent, MessageBoxModel pMessageBoxModel)    {        using (frm_MessageBox frm = new frm_MessageBox(pMessageBoxModel))        {            if (parent == null || parent.IsDisposed)            {                frm.StartPosition = FormStartPosition.CenterScreen;                 if (pMessageBoxModel.FormWidth != 0) frm.Width = pMessageBoxModel.FormWidth;                if (pMessageBoxModel.FormHeight != 0) frm.Height = pMessageBoxModel.FormHeight;                return frm.ShowDialog();            }            else            {                frm.StartPosition = FormStartPosition.CenterParent;                 if (pMessageBoxModel.FormWidth != 0) frm.Width = pMessageBoxModel.FormWidth;                if (pMessageBoxModel.FormHeight != 0) frm.Height = pMessageBoxModel.FormHeight;                return frm.ShowDialog(parent);            }        }    }}

代码比较简单，创建一个公共类，以及类型Messagebox的方法重载而已！最后一步，调用：

  private void button1_Click(object sender, EventArgs e)  {      KzxMessageBox.Show("this is a test!");      KzxMessageBox.Show("This is a test!", MessageBoxButtons.OKCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1);  }

一起看下效果：

最后，由于后续所有重写/重绘控件都在同一个项目使用，而且Dev系统引用文件较多，压缩后源码文件仍然很大，如果有需要源码的朋友，可以微信公众号联系博主，源码可以免费赠予~！有疑问的也可以CALL我一起探讨，最最后，如果觉得本篇博文对您或者身边朋友有帮助的，麻烦点个关注！赠人玫瑰，手留余香，您的支持就是我写作最大的动力，感谢您的关注，期待和您一起探讨！再会！
