Thanks Marco, that was helpful. Unfortunately the sample at

  http://www.go-mono.com/mysql.html

doesn't work, and the error message is too vague (connection refused).

using System;
 using System.Data;
 using ByteFX.Data.MySQLClient;
 
 public class Test 
 {
    public static void Main(string[] args)
    {
       string connectionString = 
          "Server=localhost;" +
          "Database=test;" +
          "User ID=myuserid;" +
          "Password=mypassword;";
       IDbConnection dbcon;
       dbcon = new MySQLConnection(connectionString);
       dbcon.Open(); 


the last line gives the following error: 

Unhandled Exception: System.Net.Sockets.SocketException: Connection refused
in (unmanaged) /usr/lib/libmono.so.0(mono_raise_exception+0x20) [0x400df3cb]

in <0x00138> 00 ByteFX.Data.MySQLClient.MySQLConnection:Open ()

I am running mysql-server from debian sid. It is version
4.0.13-2. Might that be the reason? :-(( Please tell me it isn't...


Trying to solve that, I looked into
mcs/class/ByteFX.Data/mysqlclient/Connection.cs, and I saw that the
connection string is different:

public MySQLConnection()
{
ConnectionString = "data source=localhost;user id=root;pwd=;database=mysql";
}

So I replaced the connection string with that format, but I get the same error.

What can I do?

Thanks again.

PS: of course I have started the mysql daemon and the connection string is ok.
