.net - Accessing A Subarray In .net (or The Equivalent)?

I read a an array of bytes from a file I pass this to a class that then assigns various bytes from that array to various members of varying sizes.

Ideally i would like to do something like this

memberThatIsAUShort = bitconverter.ToUShort(tempArray.subArray(3,5))
memberThatIsAShort = bitconverter.ToShort(tempArray.subArray(6,8))

Instead of looping through the array, copying the bytes to new shorter array and passing them in.
