Convert Byte array to Integer 2 bytes at a time

[Chintan Shah]

I have a byte array which looks something like

01 00 02 00 73 45 69 A5

So i have to read first 2 bytes and convert it into integer to get its value.
Same for next 2 bytes and then next 4 bytes.

Here the value for first 2 bytes (01 00) is 1, next 2 bytes (02 00) is 2.

So could some one help me on this.

There are two ways you can do this:

1) Using shifting and masking.

2) Using the BitConverter: http://msdn.microsoft.com/en-us/library/bb384066.aspx

In both cases, your numbers are in the wrong order so you'd have to prepare them. The first two bytes don't make 1, they actually make 256 in the order they appear. You'd need to reverse that order to get the correct number.

If you're doing this with shifting, the result happens naturally. You can loop through the numbers (in steps of 2). Then you can OR (|) the number into a destination, shift it left by 8 (the size of a byte), then OR in the second number.

If you're doing it with a bit converter, you'll need to copy the first byte into the second element of a new byte array and the second byte into the first element of that array, then run it through the bit converter.
