C#可视化编程技术总结：制作可视化窗体软件

笔记：
详情已经在前面的章节有列述了，这里只点出几个比较重要的：
string name = DataGridView对象.SelectedRows[0].Cells[0].Value.ToString();获取在DataGridView控件中选中的一行的第cells[0]列数据。

窗体样式：

代码如下：

主窗体，“手机销售管理系统”代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;namespace product6._10
{public partial class FrmSalesManage : Form{public FrmSalesManage(){InitializeComponent();}private void 客户添加ToolStripMenuItem_Click(object sender, EventArgs e){//客户添加FrmAddClient frmAdd = new FrmAddClient();frmAdd.MdiParent = this;frmAdd.Show();}private void 客户查询ToolStripMenuItem_Click(object sender, EventArgs e){//查询客户FrmSelectClient frmSelect = new FrmSelectClient();frmSelect.MdiParent = this;frmSelect.Show();}private void 客户查询ToolStripMenuItem1_Click(object sender, EventArgs e){//查询客户FrmSelectClient frmSelect = new FrmSelectClient();frmSelect.MdiParent = this;frmSelect.Show();}private void 客户添加ToolStripMenuItem1_Click(object sender, EventArgs e){//客户添加FrmAddClient frmAdd = new FrmAddClient();frmAdd.MdiParent = this;frmAdd.Show();}//退出所有程序private void FrmSalesManage_FormClosing(object sender, FormClosingEventArgs e){Application.Exit();}private void 安全退出ToolStripMenuItem_Click(object sender, EventArgs e){Application.Exit();}private void 安全退出ToolStripMenuItem1_Click(object sender, EventArgs e){Application.Exit();}
}
}

查询窗体：“客户查询”代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;namespace product6._10
{public partial class FrmSelectClient : Form{public FrmSelectClient(){InitializeComponent();}//刷新列表public void RefreshList(){string sql = "select * from Customer";DataTable table = DBHelper.GetDataTable(sql);ClientInformation.DataSource = table;}//初始换程序选项private void FrmSelectClient_Load(object sender, EventArgs e){RefreshList();cbType.Items.Clear();cbType.Items.Add("--请选择--");cbType.Items.Add("按姓名");cbType.Items.Add("按电话");cbType.Items.Add("按地址");cbType.Items.Add("按编号");cbType.SelectedIndex = 0;}//完善搜索信息private void btSelect_Click(object sender, EventArgs e){string key = cbCondition.Text;if(cbType.SelectedIndex == 0){//没有确切客户信息，则全能查找string sql = string.Format("select * from Customer where Custname like '%{0}%' or CustID like '%{0}%'or Custtel like '%{0}%'or CustAddress like '%{0}%'or CustSex like '%{0}%'",key);DataTable table = DBHelper.GetDataTable(sql);ClientInformation.DataSource = table;if (table.Rows.Count == 0){MessageBox.Show(string.Format("没有找到与{0}相关的联系人", key));}}//查无此人报错if (cbType.SelectedIndex == 1){//根据姓名查询客户string sql = string.Format("select * from Customer where Custname like '%{0}%'",key);DataTable table = DBHelper.GetDataTable(sql);ClientInformation.DataSource = table;if(table.Rows.Count == 0){MessageBox.Show(string.Format("没有找到与{0}相关的联系人",key));}}else if(cbType.SelectedIndex == 2){//根据电话查询客户string sql = string.Format("select * from Customer where CustTel like '%{0}%'", key);DataTable table = DBHelper.GetDataTable(sql);ClientInformation.DataSource = table;if (table.Rows.Count == 0){MessageBox.Show(string.Format("没有找到与{0}相关的联系人", key));}}else if(cbType.SelectedIndex == 3){//根据地质查询客户string sql = string.Format("select * from Customer where CustAddress like '%{0}%'",key);DataTable table = DBHelper.GetDataTable(sql);ClientInformation.DataSource = table;if (table.Rows.Count == 0){MessageBox.Show(string.Format("没有找到与{0}相关的联系人", key));}}else if(cbType.SelectedIndex == 4){//根据客户编号查询客户string sql = string.Format("select * from Customer where CustID like '%{0}%'", key);DataTable table = DBHelper.GetDataTable(sql);ClientInformation.DataSource = table;if (table.Rows.Count == 0){MessageBox.Show(string.Format("没有找到与{0}相关的联系人", key));}}}//异窗口传参数public static string id = "0";public static string name;public static string tel;public static string sex;public static string address;private void ClientInformation_CellContentClick(object sender, DataGridViewCellEventArgs e){id = ClientInformation.SelectedRows[0].Cells[0].Value.ToString();name = ClientInformation.SelectedRows[0].Cells[1].Value.ToString();tel = ClientInformation.SelectedRows[0].Cells[2].Value.ToString();sex = ClientInformation.SelectedRows[0].Cells[3].Value.ToString();address = ClientInformation.SelectedRows[0].Cells[4].Value.ToString();  }//弹出修改客户信息窗口private void btAddClient_Click(object sender, EventArgs e){//选中客户失败   if (string.IsNullOrEmpty(id) || string.IsNullOrEmpty(name) || string.IsNullOrEmpty(tel) || string.IsNullOrEmpty(sex)){MessageBox.Show(string.Format("未选中唯一联系人，\n请重新单击选择客户"));return;}FrmAmendClient frmAmend = new FrmAmendClient();frmAmend.ShowDialog();RefreshList();}//删除客户private void buDeleteClient_Click(object sender, EventArgs e){id = ClientInformation.SelectedRows[0].Cells[0].Value.ToString();name = ClientInformation.SelectedRows[0].Cells[1].Value.ToString();//给一个删除客户提示string question = string.Format("你确定要将客户{0}拉入黑名单吗", name);DialogResult result =  MessageBox.Show(question,"删除提示",MessageBoxButtons.YesNo,MessageBoxIcon.Question);if(result == DialogResult.No){return;}string sql = string.Format("delete from Customer where CustID = {0}",int.Parse(id));if (DBHelper.ExecuteNonQuery(sql)){MessageBox.Show(string.Format("客户{0}已被您从名单中拉黑",name));}else{MessageBox.Show(string.Format("客户{0}删除失败，请向管理员核实",name));}}//点击刷新列表private void button1_Click(object sender, EventArgs e){RefreshList();}
}
}

添加窗体，“添加用户”代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;namespace product6._10
{public partial class FrmAddClient : Form{public FrmAddClient(){InitializeComponent();}private void button1_Click(object sender, EventArgs e){//添加一个新客户，完善客户信息string name = textName.Text;string tel = textTel.Text;string sex = "";if(radMan.Checked == true){sex = radMan.Text;}else if(radWoman.Checked == true){sex = radWoman.Text;}string address = textAddress.Text;if(string.IsNullOrEmpty(name)|| string.IsNullOrEmpty(tel) || string.IsNullOrEmpty(sex)){MessageBox.Show("请完善客户信息");return;}string sql = string.Format("insert into Customer values('{0}','{1}','{2}','{3}')",name,tel,sex,address);if (DBHelper.ExecuteNonQuery(sql)){MessageBox.Show(string.Format("新客户{0}添加成功",name));textName.Text = "";textTel.Text = "";radMan.Checked = false;radWoman.Checked = false;textAddress.Text = "";}else{MessageBox.Show(string.Format("新客户{0}添加失败，请向管理员反映情况",name));}}//取消添加客户private void button2_Click(object sender, EventArgs e){//如果信息为空，直接关闭窗口if(string.IsNullOrEmpty(textName.Text) && string.IsNullOrEmpty(textTel.Text)&&radMan.Checked == false && radWoman.Checked == false && string.IsNullOrEmpty(textAddress.Text)){Close();}//信息不为空，清空信息textName.Text = "";textTel.Text = "";radMan.Checked = false;radWoman.Checked = false;textAddress.Text = "";}//姓名非空*号提示private void textName_TextChanged(object sender, EventArgs e){string name = textName.Text;if (string.IsNullOrEmpty(name)){labName.Text = "*";labName.ForeColor = Color.Red;}else{labName.Text = "";}}//电话非空*号提示private void textTel_TextChanged(object sender, EventArgs e){string tel = textTel.Text;if (string.IsNullOrEmpty(tel)){labTel.Text = "*";labName.ForeColor = Color.Red;}else{labTel.Text = "";}}//性别非空*号提示——男private void radMan_CheckedChanged(object sender, EventArgs e){if(radMan.Checked == false && radWoman.Checked == false){labSex.Text = "*";labSex.ForeColor = Color.Red;}else{labSex.Text =  ""; }}//性别非空*号提示——女private void radWoman_CheckedChanged(object sender, EventArgs e){if (radMan.Checked == false && radWoman.Checked == false){labSex.Text = "*";labSex.ForeColor = Color.Red;}else{labSex.Text = "";}}
}
}

修改信息，“修改客户信息”代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;namespace product6._10
{public partial class FrmAmendClient : Form{public FrmAmendClient(){InitializeComponent();}//非空验证提示private void textName_TextChanged(object sender, EventArgs e){string name = textName.Text;if(string.IsNullOrEmpty(name)){labName.ForeColor = Color.Red;labName.Text = "*";}else{labName.Text = "";}}private void textTel_TextChanged(object sender, EventArgs e){string tel = textTel.Text;if (string.IsNullOrEmpty(tel)){labTel.ForeColor = Color.Red;labTel.Text = "*";}else{labTel.Text = "";}}private void radMan_CheckedChanged(object sender, EventArgs e){if(radMan.Checked == false && radWoman.Checked == false){labSex.Text = "*";labSex.ForeColor = Color.Red;}else{labSex.Text = "";}}private void radWoman_CheckedChanged(object sender, EventArgs e){if (radMan.Checked == false && radWoman.Checked == false){labSex.Text = "*";labSex.ForeColor = Color.Red;}else{labSex.Text = "";}}//确认修改客户信息系private void button1_Click(object sender, EventArgs e){int id = Convert.ToInt32(labID.Text);string name = textName.Text;string tel = textTel.Text;string sex = "男";if (radMan.Checked){sex = radMan.Text;}else if (radWoman.Checked){sex = radWoman.Text;}if (string.IsNullOrEmpty(name) || string.IsNullOrEmpty(tel) || string.IsNullOrEmpty(sex)){MessageBox.Show("请完善用户信息");return;}string address = textAddress.Text;string sql = string.Format("update Customer set Custname = '{0}',Custtel = '{1}',Custsex = '{2}',Custaddress = '{3}' where Custid = {4}",name,tel,sex,address,id);if (DBHelper.ExecuteNonQuery(sql)){MessageBox.Show(string.Format("编号为{0}的客户信息修改成功",id));this.Close();}else{MessageBox.Show(string.Format("编号为{0}的客户信息修改失败，请向管理员反映情况",id));}}//自动根据选中异窗体传输的信息填写文本信息private void FrmAmendClient_Load(object sender, EventArgs e){labID.Text = FrmSelectClient.id;textName.Text = FrmSelectClient.name;textTel.Text = FrmSelectClient.tel;if (FrmSelectClient.sex.Equals("男")){radMan.Checked = true;}else if (FrmSelectClient.sex.Equals("女")){radWoman.Checked = true;}textAddress.Text = FrmSelectClient.address;}//保存后关闭窗口private void button2_Click(object sender, EventArgs e){Close();}
}
}
