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
1
try
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
try2
{
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" onclick="Button1_Click" Text="注册" Width="69px" />
14
15
<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" onclick="Button1_Click" Text="注册" Width="69px" />14

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 }
9
10
if (Membership.ValidateUser(UserName.Text,Password.Text))2
{3
FormsAuthentication.RedirectFromLoginPage(UserName.Text, false); 4
}5
else6
{7
Response.Write("登录失败！");8
}9
10
//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" onclick="Button1_Click" 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>
9
10
11
<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" onclick="Button1_Click" 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>9

３、找回密码

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

还有一此用户管理的API，在下一篇文章中叙述。
