Unmanaged Array Example

Didn't get any clue. let me explain the problem.

In C# I am already using the managed array on whose values I am doing some processing.

Idea is to convert those array to unmanaged arrays(because of performance) but data shouldn't be lost.

For example

int[] myArray = new int[]{1,2,3,4,5,6}

here when I do myArray[1] , it returns 2.

I want to convert this to unmanaged array and make sure values remains same.

may be if there is way to check if values in managed and unmanaged array is same.

Can you pls , give answer in reference to this sample shared.
