HEX Operations in C#

[RobLefevre]

I ran into this ridiculous problem while working on a checksum problem.

I currently have a string containing the HEX values of a checksum.
Is there any way in .net to perform AND operations on two HEX values?

I need to AND my result with 7F.

Does the bitwise "and" operator not work for you?

i am converting my complete values to binary values then i am applying my logic there .

Hope may help you too.

Int.Parse() can be overloaded to accept HEX values
(e.g. int.Parse("2A") will give you 42)
You can typecast to a byte do your AND operations like that?

You cant do?

int x;
x = 0x7F & 0xA;

In this case x would be 137 or in hex 89 or in binary 10001001?

You can, but if you have a string like this "A3 D7 22 3E FA" you would need some sort of automated system.
