Question

How to convert an int[,] to byte[] in C#?
Some code will be appreciated

EDIT:

I need a function to perform the following:

byte[] FuncName (int[,] Input)

Answer 1

Since there is very little detail in your question, I can only guess what you’re trying to do… Assuming you want to “flatten” a 2D array of ints into a 1D array of bytes, you can do something like that :

byte[] Flatten(int[,] input)
{
    return input.Cast<int>().Select(i => (byte)i).ToArray();
}

Note the call to Cast : that’s because multidimensional arrays implement IEnumerable but not IEnumerable<T>
