有没有办法配置ASP.NET SqlMembershipProvider,以便Email是可选的,但提供时必须是唯一的?
我只找到强制要求发送电子邮件的requiredUniqueEmail
属性(web.config)。我是否必须将其保留,并在帐户注册过程中自行检查现有的电子邮件地址?
或者有更好的方法来处理这种情况吗?

一种简单但可能有风险的方法是直接修改存储过程来执行此操作。
通过替换:
修改aspnet_Membership_CreateUser
IF (@UniqueEmail = 1)
BEGIN
IF (EXISTS (SELECT *
FROM dbo.aspnet_Membership m WITH ( UPDLOCK, HOLDLOCK )
WHERE ApplicationId = @ApplicationId AND LoweredEmail = LOWER(@Email)))
BEGIN
SET @ErrorCode = 7
GOTO Cleanup
END
END
与
IF (EXISTS (SELECT *
FROM dbo.aspnet_Membership m WITH ( UPDLOCK, HOLDLOCK )
WHERE ApplicationId = @ApplicationId AND LoweredEmail = LOWER(@Email)))
BEGIN
SET @ErrorCode = 7
GOTO Cleanup
END
我说它有风险,因为没人会指望你修改它,你最好记录好这个变化。
