實現自定義和的MembershipUser自定義的MembershipProvider

我嘗試實現自定義MembershipPriver使用自定義中的MembershipUser我自己的數據庫（一個具體的用戶表型號）：實現自定義和的MembershipUser自定義的MembershipProvider

       } 
      } 
     } 
    } 
}

我編譯時已經有些錯誤

構件 'System.Web.MembershiProvider.CreateUser（字符串，字符串，字符串，字符串，字符串，布爾，對象out System.Web.Security.MembershipCreateStatus）'

2) iTwitterMembershipProvider.CreateUser(string,

串，串，字符串，字符串，布爾，對象out System.Web.Security.MembershipCreateStatus） '：發現重寫

3)'iTwitterMembershipProvider.GetUser(string,

布爾沒有合適的方法）'：換貨政... RN類型必須是 'System.Web.Security.MembershipUser' 匹配重寫的成員 'System.Web.Security.MembershipProvider.GetUser（字符串，布爾）'

我在這裏封鎖。

謝謝。

將CreateUser和GetUser的返回類型更改爲基類MembershipUser。當你調用這些方法時，你可以將它轉換爲iTwitterMembershipUser類型。例如，在CREATEUSER更改return語句

return (iTwitterMembershipUser) GetUser(login);

它一直以來我看着的MembershipProvider東西很長一段時間，我不記得所有的接口。但是你的錯誤在於你正在實現一個抽象基類，它有你沒有實現的抽象方法。如果您實現了一個接口，或者從具有抽象方法的類繼承，那麼您的類必須提供這些成員的實現。在你的情況下，你的返回類型與抽象方法的返回類型不匹配。
