Terraria cooding problems

When i try to debug my mod it says: "TypeIntializationException was unhandeled"
What did i do wrong?
Here's my code:

namespace Terraria
{
using System;
using System****;
//using System.Windows.Forms;

internal static class Program
{
private static void Main(string[] args)
{
Terraria.Main main = new Terraria.Main();
try
{
for (int i = 0; i < args.Length; i++)
{
if ((args[i].ToLower() == "-port") || (args[i].ToLower() == "-p"))
{
i++;
try
{
Netplay.serverPort = Convert.ToInt32(args[i]);
}
catch
{
}
}
if ((args[i].ToLower() == "-join") || (args[i].ToLower() == "-j"))
{
i++;
try
{
main.AutoJoin(args[i]);
}
catch
{
}
}
if ((args[i].ToLower() == "-pass") || (args[i].ToLower() == "-password"))
{
i++;
Netplay.password = args[i];
main.AutoPass();
}
if (args[i].ToLower() == "-host")
{
main.AutoHost();
}
if (args[i].ToLower() == "-loadlib")
{
i++;
string path = args[i];
main.loadLib(path);
}
}
//Steam.Init();
// if (Steam.SteamInit)
// {
main.Run();
// }
// else
// {
// MessageBox.Show("Please launch the game from your Steam client.", "Error");
//}
}
catch (Exception exception)
{
try
{
using (StreamWriter writer = new StreamWriter("client-crashlog.txt", true))
{
writer.WriteLine(DateTime.Now);
writer.WriteLine(exception);
writer.WriteLine("");
}
// MessageBox.Show(exception.ToString(), "Terraria: Error");
}
catch
{
}
}
finally
{
if (main != null)
{
main.Dispose();
}
}
}
}
}
