SQL CLR-Base-64 char数组或字符串的长度无效

Question

I've created a user defined function and executed. It returns the below error message. Need your support.

public partial class UserDefinedFunctions
{

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

Error:

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.

You can try following :

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();
    }
}
