I\'m getting an error when I attempt to use the following static function.

Error:

Expected class, delegate, enum, interface, or struct

I ran into this problem when getting re-acquainted with P-Invoke. Femaref had it right. Here's some sample code for quick visualization purposes:

Working Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices; 

namespace ConsoleApplication2
{
    class Program
    {
        [DllImport("kernel32.dll", CharSet = CharSet.Auto)]
        public static extern IntPtr GetModuleHandle(string lpModuleName);

        static void Main(string[] args)
        {

        }
    }
}

Broken Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;

[DllImport("kernel32.dll", CharSet=CharSet.Auto)]
public static extern IntPtr GetModuleHandle(string lpModuleName);

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {

        }
    }
}
