Import DLL and call functions via value

I wan to import a DLL and use its functions but i want to assign the dll to a value so i dont end up overiding methods

Example of how I want to do it

mydll = [DllImport("MyDll.dll")]
mydll.SayHi();
// So I don't override this:
public void SayHi() { Console.WriteLine("Hello!!!"); }

Any way to acheive this?

Import the DLL in a wrapper class. 

using System;
using System.Runtime.InteropServices;

// Namespace is optional but generally recommended.
namespace MyDLLImports
{
    static class MyDLLWrapper
    {
        // Use DllImport to import the SayHi() function.
        [DllImport("mydll.dll", CharSet = CharSet.Unicode)]
        public static extern void SayHi();
    }
}

class Program
{
    static void SayHi()
    {
        // whatever...
    }
    static void Main()
    {
        // Call the different SayHi() functions.
        MyImports.MyDLLWrapper.SayHi();
        SayHi();
    }
}

See the MSDN docs on the DLLImport attribute for further details. You may also need to declare calling conventions, different character encodings, the DLL's main entry point, etc.
