There is an int variable, say 0xFF00FF00. You need to get a byte array consisting of {FF, 00, FF, 00} elements.

Question. Are there any built-in mechanisms in .NET for this task, if there are any?

    Use BitConverter: BitConverter.GetBytes(Int32)

      You can do it with your hands:

       int myInt = 12345; byte[] myByte = { (byte)myInt, (byte)(myInt >> 8), (byte)(myInt >> 16), (byte)(myInt >> 24) };
