How can I convert a int array to a byte array.
In an other word, I need to write a int array into a
memorystream. How can I do it?

Thanks

The easiest way is to create a BinaryWriter on top of the
MemoryStream, then iterate through the int[] and call Write for each
element.

You can also use the BitConverter class to get byte[4] from an int.

int[] ai = new int[] { 0x11223344, 0x55667788 };
byte[] ab = new byte[ Buffer.ByteLength(ai) ];
Buffer.BlockCopy( ai, 0, ab, 0, ab.Length );
