[Pkg-mono-devel] need help to connect to mysql with C#

[Star Liu]

I want to connect to mysql with C# of mono, my code get strange
error "System.ArgumentException: Stream is not a valid .resources
file" when it runs, could you help me solve it? I use debian sid
amd64.

Here is my code:

using System;
using System.IO;
using System.Xml;
using System.Data;
using MySql.Data.MySqlClient;


namespace StarConsole
{
       class MainClass
       {
               public static void Main(string[] args)
               {
                  string connectionString ="Server=localhost;Database=Star;User
ID=root;Password=mysql10veana;Pooling=false";
              IDbConnection dbcon = new MySqlConnection(connectionString);
              dbcon.Open();
              IDbCommand dbcmd = dbcon.CreateCommand();
              string sql ="insert into Departments(deptno,deptname)
values('0004','caohejin');";
              dbcmd.CommandText = sql;
                  dbcmd.ExecuteNonQuery();
              dbcmd.Dispose();
              dbcmd = null;
              dbcon.Close();
              dbcon = null;

               }
       }
}

it compiles successfully, but when it runs, it gets error, here is the
debug info in monodevelop:
