Question

It is first time I am trying to use DllImort in C#. But it is not appearing in InteliSense. I have added

using System.Runtime.InteropServices;

But it is not working again. Instead this [DllImportAttribute] is shown.

What am I doing wrong?

Answer 1

You do nothing wrong. Use this attribute to define the managed signature for the method you want to import.

As Example

[DllImport("kernel32.dll", BestFitMapping = false, 
                CharSet = CharSet.Auto, SetLastError = true)]
private static extern IntPtr GetModuleHandle(string moduleName);

Look in MSDN for all possible parameter for DllImport
