我已经在这个令人沮丧的bug上工作了几天，但似乎无法将手指放在它上面。我试图使用以下代码在ASP.NET网站上创建用户：
MembershipCreateStatus createStatus;
MembershipUser newUser = Membership.CreateUser(UserName.Text, Password1.Text, Email1.Text, SecQ.Text, SecA.Text, true, out createStatus);
switch (createStatus)
{
case MembershipCreateStatus.Success:
CreateAccountResults.Text = "The user account was successfully created!";
CreateAccountResults.ForeColor = System.Drawing.Color.Green;
break;
case MembershipCreateStatus.DuplicateEmail:
CreateAccountResults.Text = "There already exists a user with this email address.";
break;
case MembershipCreateStatus.DuplicateUserName:
CreateAccountResults.Text = "There already exists a user with this username.";
break;
case MembershipCreateStatus.InvalidEmail:
CreateAccountResults.Text = "There email address you provided in invalid.";
break;
case MembershipCreateStatus.InvalidAnswer:
CreateAccountResults.Text = "There security answer was invalid.";
break;
case MembershipCreateStatus.InvalidPassword:
CreateAccountResults.Text = "The password you provided is invalid. It must be seven characters long and have at least one non-alphanumeric character.";
break;
default:
CreateAccountResults.Text = "There was an unknown error; the user account was NOT created.";
break;
但是，如果我在数据库中有“电子邮件”一个唯一列，如果我输入已经采用的电子邮件地址，它将返回duplicateUserName（而不是返回DuplicateEmail）我试图谷歌，甚至只是阅读代码试图理解这个问题，但我似乎无法准确找到它出错的地方。
以下是尝试创建用户时调用的附加存储过程：

如果有人能指出我正确的方向来获得这个决心，我将不胜感激。我觉得这将是一件非常小的事情，我忽略了。
谢谢。

如果您不想为用户提供唯一的电子邮件，则必须在requiresUniqueEmail文件中将属性false设置为Web.Config。
例如
<membership defaultProvider="SqlProvider"
userIsOnlineTimeWindow="15">
<providers>
<add
name="SqlProvider"
type="System.Web.Security.SqlMembershipProvider"
connectionStringName="SqlServices"
applicationName="MyApplication"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="true"
requiresUniqueEmail="false"
passwordFormat="Hashed"
maxInvalidPasswordAttempts="5"
passwordAttemptWindow="10" />
</providers>
</membership>

存储过程在检查电子邮件地址之前检查是否存在具有该用户名的记录。如果您使用电子邮件地址作为用户名，则会返回与MembershipCreateStatus.DuplicateUserName对应的值，并且永远不会检查电子邮件地址。
