asp.net:specify錯誤MembershipCreateStatus.ProviderError使用c＃

Question

也許這個問題聽起來很愚蠢。 以上聲明中提供者是誰？ 提供所需錯誤的程序員，創建會員資格的用戶還是其他人？ 具體來說，我想顯示錯誤，當用戶鍵入超過最大長度字符如下： ps。找到在geterrormessage方法*行...

UsernameTextbox.MaxLength = 15; 
    if (UsernameTextbox.Text.Length > UsernameTextbox.MaxLength) 
    { 
     status = MembershipCreateStatus.ProviderError; 
     Msg.Text = GetErrorMessage(status); 
    } 


public string GetErrorMessage(MembershipCreateStatus status) 
{ 
    switch (status) 
    { 


    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."; 
    //****** STAR LINE:i want to show the following message but i don't know if the--> 
    //-->the provider error method can let me do this 
    case MembershipCreateStatus.ProviderError: 
    return "field outreached the maximum length of characters which is:"; 

    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."; 
    } 
}

提供程序是內置在默認的MembershipProvider，你可以通過創建從的MembershipProvider派生的類指定自己的實現。
