Use the appropriate exception type in the catch block.

Use the appropriate MySQL classes.

using MySql.Data.MySqlClient;

// class level var or whatnot:
string connString = @"server=theHostName;userid=dbuser123;password=OpenSesame7;database=my_db_name";


public void connect()
{
    try
    {
        conn = new MySqlConnection(connString); // read above comments for (conn)
        conn.Open();
    }
    catch (MySqlException ex)
    {
        MessageBoxButtons buttons = MessageBoxButtons.OK;
        string s="MySqlException: "+ex.ToString();
        MessageBox.Show(s,"Error",buttons);
    }
    finally
    {
        if (conn != null)
        {
            //conn.Close();
        }
    }
}

Answer 2

Catching or handling exceptions in C# generally requires a try-catch statement.

The syntax is essentially as follows:

try
{
    // operation likely to cause error
} 
catch (Exception e){
    // handle error
    Console.WriteLine("Exception: " + e);
}

Console.Read();

So wrap your con.Open() logic in a try-catch statement like so:

try
{
    Con.Open();
} 
catch (Exception e){
    // handle error
    Console.WriteLine("Possible MySQL Exception: " + e);
}

Additionally, you can add a finally block to the end of a try-catch statement, which executes its code regardless of whether an exception was handled or not:

    try
{
    // attempt to do something here
    con.Open();
} 
catch (Exception e){
    // handle error
    Console.Writeline("Exception: " + e);
}
finally 
{
    Console.Writeline("This runs no matter if an exception is thrown or not!");
}

Console.Read();
