You can use System.Buffer.BlockCopy to do this:

byte[] byteArray = new byte[uintArray.Length * 4];
Buffer.BlockCopy(uintArray, 0, byteArray, 0, uintArray.Length * 4];

This will be much more efficient than using a for loop or some similar construct. It directly copies the bytes from the first array to the second.

To convert back just do the same thing in reverse.
