Powershell Byte array to INT

Question 1

I have a byte array with two values: 07 and DE (in hex).

What I need to do is somehow concatenate the 07DE and get the decimal value from that hex value. In this case, it is 2014.

My code:

# This line gives 11 bytes worth of information
[Byte[]] $hexbyte2 = $obj.OIDValueB

# All I need are the first two bytes (the values in this case are 07 and DE in HEX)
[Byte[]] $year = $hexbyte2[0], $hexbyte2[1]

# This line gives 11 bytes worth of information

[Byte[]] $hexbyte2 = $obj.OIDValueB

# All I need are the first two bytes (the values in this case are 07 and DE in HEX)

[Byte[]] $year = $hexbyte2[0], $hexbyte2[1]

How do I combined these to make 07DE and convert that to an int to get 2014?

Question 2

Another option is to use the .NET System.BitConvert class:

C:\PS> $bytes = [byte[]](0xDE,0x07)
C:\PS> [bitconverter]::ToInt16($bytes,0)
2014

C:\PS> $bytes = [byte[]](0xDE,0x07)

C:\PS> [bitconverter]::ToInt16($bytes,0)

2014
