ASP.NET MVC4 WebSecurity.ConfirmAccount（字符串令牌）的long到int转换异常

Question

This seems to be a confusion to me. I'm working with MVC4 Simple membership just to help automate my Account process. all seems ok except when i invoke the WebSecurity.ConfirmAccount(string token) and WebSecurity.ResetPassword(string token, string newPassword) methods. both method throw and exception of long to in conversion error when passed with the correct token generated for the user but execute without error and return false when passed with the wrong token. Am i making any mistake?

Answer 1

You cannot convert type long to int because long holds 64 bits from memory and int holds 32 bits from memory. Trying to convert long to int will therefore cause an exception.

Answer 2

It sounds like your UserId column was created as a bigint rather than an int . The WebMatrix.WebData.SimpleMembershipProvider expects that column to be an int :
