SQL CLR - Base-64字符数组或字符串的无效长度

Question

我创建了用户定义的函数并执行。它返回下面的错误消息。需要你的支持。

public partial class UserDefinedFunctions 
{ 

    [Microsoft.SqlServer.Server.SqlFunction] 
    public static SqlBoolean SqlFunctValidateUserCred() 
    { 
      bool verify = Crypto.VerifyHashedPassword("test", "test1"); 
      return verify; 
    } 
} 

错误：

Msg 6522, Level 16, State 2, Line 11 A .NET Framework error occurred during execution of user-defined routine or aggregate "SqlFunctValidateUserCred": System.FormatException: Invalid length for a Base-64 char array or string. System.FormatException: at System.Convert.FromBase64_Decode(Char* startInputPtr, Int32 inputLength, Byte* startDestPtr, Int32 destLength) at System.Convert.FromBase64CharPtr(Char* inputPtr, Int32 inputLength)
at System.Convert.FromBase64String(String s) at System.Web.Helpers.Crypto.VerifyHashedPassword(String hashedPassword, String password) at UserDefinedFunctions.SqlFunctValidateUserCred()

System.Web.Helpers.Crypto.VerifyHashedPassword：

Parameters
hashedPassword
Type: System.String
The previously-computed RFC 2898 hash value as a base-64-encoded string.

您可以尝试以下操作：

public static void AddUsersToDatabase(string databaseserver, string databasename, string usertobeadded) 
{ 
    using (SqlConnection conn = 
     new SqlConnection("server=" + databaseserver + 
         "; database=" + databasename + 
         "; User ID=WPDOMAIN\\spdev; Integrated Security=SSPI; password=Password123;")) 
    { 
     conn.Open(); 
     string password = "Password123"; 
     string sql = "CREATE LOGIN " + usertobeadded + " WITH PASSWORD = '" + 
     password + "'; USE " + databasename + "; CREATE USER " + usertobeadded + " FOR LOGIN " + usertobeadded + ";"; 

     SqlCommand cmd = new SqlCommand(sql); 
     cmd.ExecuteNonQuery(); 


     conn.Close(); 
    } 
}
