[Mono-list] cannot connect to mysql server

[StarLiu]

Greetings!
 
My code builds successfully, but it cannot connect to mysql server when it
runs, i searched in google about the error information:
"Stream is not a valid .resources file"
very little information about it, and no solution to it. so i ask here.
 
Here is the 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=password;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();
  reader.Close();
  reader = null;*/
  dbcmd.Dispose();
  dbcmd = null;
  dbcon.Close();
  dbcon = null;
 
}
}
}
 
here is the debug information output by monodevelop
