것은 나에게이 문제를 당신은 그것이의 Web.config의 회원 섹션에 선언 된대로 CustomMembersipUser의 인스턴스를 만들 때 공급자의 이름을 전달해야

Answer 1

를 해결하는 데 도움이 바랍니다. CustomMembershipProvider의 값을 하드 코딩하는 대신에 CustomMembershipProvider.Initialize 메서드가 호출 될 때이 값을받는 private 필드를 사용할 수 있습니다. 예를

를 들어

public class CustomMembershipProvider: MembershipProvider 
{ 
    private providerName = null; 
    ... 

    public override void Initialize(string name, NameValueCollection config) 
    { 
     providerName = name; // The friendly name of the provider 
     ... 
    } 

    public override MembershipUser TestCreateUser(string username, bool userIsOnline) 
    { 
     CustomMembershipUser membershipUser = new CustomMembershipUser(providerName, 
       username, 
       Guid.Parse(userID.ToString()), 
       email, 
       passwordQuestion, 
       comment, 
       isApproved, 
       isLockedOut, 
       creationDate, 
       lastLoginDate, 
       lastActivityDate, 
       lastPasswordChangedDate, 
       lastLockedOutDate, "ss"); 
     ... 
    } 
}
