Found this in some code I've been maintaining/expanding. Quite clever.

Picture an array of bytes in binary

00000111 11100000 00000000 00000000

Now picture an Int32 in Binary
00000000000000000000000000000000

To grab a Little Endian Integer (16 bits) out of the array.

Take the second array element
11100000

Assign it to the Int32 variable
00000000000000000000000011100000

Bit shift it up by 8
00000000000000001110000000000000

Now OR it with the first Array element - could also just add.
<pre>
00000000000000001110000000000000
or 00000000000000000000000000000111
= 00000000000000001110000000000111
</pre>
