사용자를 만들거나 생성에 실패하면 저장시 더 이상 시도 할 때마다 MembershipCreteStatus가 두 번 이상 반환됩니다.

Question

WCF 및 Membership.CreateUser를 사용하여 Silverlight 웹 앱을 사용하여 새 사용자를 만듭니다.

사용자를 성공적으로 만든 다음 다른 사용자를 만들면 "사용자가 성공적으로 생성되었습니다"라는 상태 메시지가 두 번 표시됩니다. 또는 사용자 이름이 이미 있기 때문에 새 사용자를 만들기위한 첫 번째 시도가 실패한 경우 추가 시도는 상태 메시지를 두 번 이상 가져옵니다. 방법

tmsClient.CreateNewUserCompleted += new EventHandler<CreateNewUserCompletedEventArgs>(tmsClient_CreateNewUserCompleted); 
tmsClient.CreateNewUserAsync(nu.UserName, nu.Password, nu.Email, nu.SecurityQuestion, nu.SecurityAnswer); 

에

내 WCF 서비스 코드

[OperationContract] 
public MembershipCreateStatus CreateNewUser(string userName, string password, string email, string securityQuestion, string securityAnswer) 
{ 
    MembershipCreateStatus status = new MembershipCreateStatus(); 
    MembershipUser newUser = Membership.CreateUser(userName, password, email, securityQuestion, securityAnswer, true, out status); 

    return status; 
} 

내 전화 내 이벤트

void tmsClient_CreateNewUserCompleted(object sender, CreateNewUserCompletedEventArgs e) 
{ 
    MembershipCreateStatus status = e.Result; 
    string result = GetErrorMessage(status); 
    MessageBox.Show(result); 
} 

그리고 마지막으로 따라 GetErrorMessage 방법을 완료

public string GetErrorMessage(MembershipCreateStatus status) 
{ 
    switch (status) 
    { 
     case MembershipCreateStatus.Success: 
      return "The user was successfully created."; 

     case MembershipCreateStatus.DuplicateUserName: 
      return "Username already exists. Please enter a different user name."; 

     case MembershipCreateStatus.DuplicateEmail: 
      return "A username for that e-mail address already exists. Please enter a different e-mail address."; 

     case MembershipCreateStatus.InvalidPassword: 
      return "The password provided is invalid. Please enter a valid password value."; 

     case MembershipCreateStatus.InvalidEmail: 
      return "The e-mail address provided is invalid. Please check the value and try again."; 

     case MembershipCreateStatus.InvalidAnswer: 
       return "The password retrieval answer provided is invalid. Please check the value and try again."; 

     case MembershipCreateStatus.InvalidQuestion: 
       return "The password retrieval question provided is invalid. Please check the value and try again."; 

     case MembershipCreateStatus.InvalidUserName: 
       return "The user name provided is invalid. Please check the value and try again."; 

     case MembershipCreateStatus.ProviderError: 
      return "The authentication provider returned an error. Please verify your entry and try again. If the problem persists, please contact your system administrator."; 

     case MembershipCreateStatus.UserRejected: 
      return "The user creation request has been canceled. Please verify your entry and try again. If the problem persists, please contact your system administrator."; 

     default: 
      return "An unknown error occurred. Please verify your entry and try again. If the problem persists, please contact your system administrator."; 
    } 
} 

왜 이런 일이 발생했는지에 대한 아이디어가 있습니까? 텍사스

나는 그냥 CreateNewUserAsync 메소드를 호출 한 후 제거하지 전에 CreateNewUserCompleted에 대한 처리기를 추가 같아요. tmsClient_CreateNewUserCompleted 방법을 제대로 사용하려면 다음과 같이 sth로 표시되어야합니다.

void tmsClient_CreateNewUserCompleted(object sender, CreateNewUserCompletedEventArgs e) 
{ 
    tmsClient.CreateNewUserCompleted -= new EventHandler<CreateNewUserCompletedEventArgs>(tmsClient_CreateNewUserCompleted); 
    MembershipCreateStatus status = e.Result; 
    string result = GetErrorMessage(status); 
    MessageBox.Show(result); 
}
