Hello friend this will help you...

使用表单身份验证:

Use forms Authentication:

<authentication mode="Forms">
      <forms loginurl="Login.aspx" defaulturl="Default.aspx" path="/" protection="All" timeout="30" />
    </authentication>

在web.config中定义授权:

Define Authorization in web.config:

<authorization>
  <deny users="?" />
</authorization>

如果您希望匿名用户访问特定页面，请尝试添加位置，

If you want anonymous user to access particular page then try adding locations,

<location path="Join.aspx">
  <system.web>
    <authorization>
      <allow users="*" />
    </authorization>
  </system.web>
</location>

在web.Config中，您需要更改一些值.

In web.Config you need to change some values.

<authentication mode="Forms">
      <forms loginurl="Login.aspx" defaulturl="Home.aspx" path="/">
</forms></authentication>
<authorization>
  <deny users="?" />
</authorization>

在Login.aspx.cs页面中，您需要通过cookie对用户进行身份验证

In Login.aspx.cs Page you need to authenticate the user by cookies

// Your method to auth User

if (IsAuth)
{

// Create the authentication ticket and store the roles in the custom UserData property of the authentication ticket
 FormsAuthenticationTicket authTicket = new
                                FormsAuthenticationTicket(1, // version
                                 txtUserId.Value,           // user name
                                 DateTime.Now,               // creation
                                 DateTime.Now.AddMinutes(1),// Expiration
                                 false,                      // Persistent
                                 userData,                    // User data      
                                 FormsAuthentication.FormsCookiePath);
// Now encrypt the ticket.
string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
// Create a cookie and add the encrypted ticket to the 
// cookie as data.
HttpCookie authCookie =
new HttpCookie(FormsAuthentication.FormsCookieName,encryptedTicket);
// Add the cookie to the outgoing cookies collection. 
Response.Cookies.Add(authCookie);
// Redirect the user to the originally requested page
Response.Redirect(FormsAuthentication.GetRedirectUrl(txtUserId.Value, true));

}
