Asp.net官方标准控件实现用户的管理，虽然简单，但控件封装性很强，开发人员不能明白做了什么样的调用，还用别一方面，标准控件的使用，很大程度上限制了程序的可变性。如果自开发一整套用户管理系统，可行，但又失去了标准用户控件的作用，于是用API来管理用户，成为一个很好的先择，下面我列出主要（不　全部）的用户管理API实例：

１、注册用户
用Membership.CreateUser来创建设新用户，注意密友要包含一个符号，Membership位于System.Web.Security命名空间内。

//cs

   

1try
2                {
3                        MembershipCreateStatus MCS;
4                        Membership.CreateUser(name.Text, password.Text,email .Text ,question .Text,answer .Text ,true , out MCS );
5                        Response.Write(MCS.ToString ());
6                }
7                catch(Exception s)
8                {
9                        //异常处理代码
10                }
11

//Aspx代码

1     <asp:Label ID="Label1" runat="server" Text="用户名："></asp:Label>            
2     <asp:TextBox ID="name" runat="server" Width="196px"></asp:TextBox>        
3     <asp:Label ID="Label2" runat="server" Text="密码："></asp:Label>    
4     <asp:TextBox ID="password" runat="server" Width="197px"></asp:TextBox>    
5     <asp:Label ID="Label3" runat="server" Text="确认密码："></asp:Label>
6     <asp:TextBox ID="OtherPass" runat="server" Width="196px"></asp:TextBox>            
7     <asp:Label ID="Label4" runat="server" Text="电子邮件："></asp:Label>    
8     <asp:TextBox ID="email" runat="server" Width="193px"></asp:TextBox>    
9     <asp:Label ID="Label5" runat="server" Text="安全提示问题："></asp:Label>                
10     <asp:TextBox ID="question" runat="server" Width="189px"></asp:TextBox>    
11     <asp:Label ID="Label6" runat="server" Text="安全答案："></asp:Label>    
12     <asp:TextBox ID="answer" runat="server" Width="187px"></asp:TextBox>            
13     <asp:Button ID="Button1" runat="server" Text="注册" Width="69px" />

２、用户登录

用户登录用Membershi.ValidateUser来验证用户名和密码。如果通过验证，调用FormsAuthentication.RedirectFromLoginPage导向目标页面（这里以及后面的一些设置都是配合Forms验证展开，都预先在web.config中配置好Forms的验证策略）。
//cs代码，在登录按钮的单击事件注册的方法中

1if (Membership.ValidateUser(UserName.Text,Password.Text))
2                {
3                        FormsAuthentication.RedirectFromLoginPage(UserName.Text, false);    
4                }
5                else
6                {
7                        Response.Write("登录失败！");
8                }

//Aspx代码

1<asp:Label ID="Label1" runat="server" Text="用户名："></asp:Label>
2 <asp:TextBox ID="UserNmae" runat="server"></asp:TextBox>
3 <asp:Label ID="Label2" runat="server" Text="密码："></asp:Label>
4 <asp:TextBox ID="Password" runat="server"></asp:TextBox>
5 <asp:Button ID="Login_But" runat="server" Text="登录"    
6     Width="69px" />
7 <asp:HyperLink ID="FindPass_HL" runat="server" NavigateUrl="~/FindPassword.aspx">忘记密码</asp:HyperLink>
8<asp:HyperLink ID="Reg_HL" runat="server" NavigateUrl="~/register.aspx">注册</asp:HyperLink>

 ３、找回密码

//cs

Cs中的邮件发方法，关于一些邮件的配置是在web.confing中存放，方法中有相关的获取方法

1using System;
2using System.Collections;
3using System.Configuration;
4using System.Data;
5using System.Web;
6using System.Web.Security;
7using System.Web.UI;
8using System.Web.UI.HtmlControls;
9using System.Web.UI.WebControls;
10using System.Web.UI.WebControls.WebParts;
11using System.Web.Configuration;
12using System.Net.Configuration;
13using System.Net.Mail ;
14public partial class FindPassword : System.Web.UI.Page
15{
16        protected void Page_Load(object sender, EventArgs e)
17        {
18                if (!IsPostBack)
19                {
20                        Wizard1.ActiveStepIndex = 0;
21                }
22        }        
23        protected void Wizard1_NextButtonClick(object sender, WizardNavigationEventArgs e)
24        {
25                try
26                {
27                        Label1.Text = "问题是：" + Membership.GetUser(Quest_TB.Text).PasswordQuestion;
28                }
29                catch (Exception ee)
30                {
31                        Response.Write("异常,详细错误："+ee.Message);
32                }
33        }
34        protected void Wizard1_FinishButtonClick(object sender, WizardNavigationEventArgs e)
35        {
36                try
37                {
38                        Configuration c = WebConfigurationManager.OpenWebConfiguration(@"~\web.config"); ;
39                        NetSectionGroup ns = NetSectionGroup.GetSectionGroup(c);
40                        string forms = ns.MailSettings.Smtp.From;
41                        string hosts = ns.MailSettings.Smtp.Network.Host;
42                        int ports = ns.MailSettings.Smtp.Network.Port;
43                        string usernames = ns.MailSettings.Smtp.Network.UserName;
44                        string passwords = ns.MailSettings.Smtp.Network.Password;
45                        MailAddress from = new MailAddress(forms);
46                        MailAddress to = new MailAddress(Membership.GetUser(TextBox1.Text).Email);
47                        MailMessage message = new MailMessage(from, to);
48                        message.Subject = "密码";
49                        string nr = "您好：你的密码为：" + Membership.GetUser(Quest_TB.Text).ResetPassword(Answer_TB.Text);
50                        message.Body = nr;
51                        SmtpClient client = new SmtpClient(hosts, ports);
52                        client.Send(message);
53                }
54                catch (Exception ee)
55                {
56                        Response.Write("发送邮箱密码错误！详细信息："+ee.Message);
57                }                    
58        }
59}

//Aspx代码

1<asp:Wizard ID="Wizard1" runat="server" ActiveStepIndex="2"    
2                DisplaySideBar="False" Height="103px"    
3                onfinishbuttοnclick="Wizard1_FinishButtonClick"    
4                onnextbutt Width="168px">
5                <WizardSteps>
6                        <asp:WizardStep runat="server" title="用户名">

8                                <asp:TextBox ID=" Quest_TB" runat="server" Width="141px"></asp:TextBox>
9                        </asp:WizardStep>
10                        <asp:WizardStep runat="server" title="问题">
11                                <asp:Label ID="Label1" runat="server" Text="问题是："></asp:Label>

20                        </asp:WizardStep>
21                </WizardSteps>
22</asp:Wizard>        
23//web.config中的配置
24位于configuration标签中
25<system.net>
26            <mailSettings>
27                    <smtp from="[email]axzxs2001@163.com[/email]">
28                            <network host="smtp.163.com" password="*********" userName="axzxs2001" />
29                    </smtp>

还有一此用户管理的API，在下一篇文章中叙述。
