推荐答案

您可以从 SimpleMembershipProvider 继承并像这样覆盖 ValidateUser 方法.

You could inherit from the SimpleMembershipProvider and just override the ValidateUser method like this.

public class ExtendedSimpleMembershipProvider : SimpleMembershipProvider
{
    public override bool ValidateUser(string login, string password)
    {
        // check to see if the login passed is an email address
        if (IsValidEmail(login))
        {
            string actualUsername = base.GetUserNameByEmail(login);
            return base.ValidateUser(actualUsername, password);
        }
        else
        {
            return base.ValidateUser(login, password);
        }

    }

    bool IsValidEmail(string strIn)
    {
        // Return true if strIn is in valid e-mail format.
        return Regex.IsMatch(strIn, @"^([w-.]+)@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.)|(([w-]+.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(]?)$");
    }

}

这只是一种方法.您可以编写自己的 MembershipProvider 但如果您只需要更改 ValidateUser 方法，这应该可以工作.

This is just one approach. You could write your own MembershipProvider but if you only need to change the ValidateUser method this should work.

将以下配置添加到 web.config 以设置提供程序.

Add the following configuration to the web.config to setup the provider.

  <membership defaultProvider="ExtendedSimpleMembershipProvider">   
    <providers>
    <clear/>
    <add name="ExtendedSimpleMembershipProvider"
         type="MyProject.Web.SimpleMembershipProvider, MyProject.Web"/>
    </providers>
  </membership>

这应该会让你朝着正确的方向前进.

That should get you going in the right direction.
