A signed char in C/C++ is not a 'char' in C#, it's an 'sbyte' - no cast required:

sbyte tempMask;

tempMask = 0xff;

It's just a simple initialisation of a variable tempMask in a hexadecimal system. http://en.wikipedia.org/wiki/Hexadecimal OxFF = 15*16^0+ 15*16^1 = 255 . In C# you cannot init char with int value without explicit conversion but you can write : char tempMask = (char)0xFF;, or if you really want a 8-bit integer - try byte tempMask = 0xFF;

It initializes tempMask with a byte containing value 0xFF

In C#, you can write

tempMask = (char)0xff;

or

tempMask = Convert.ToChar(0xff);
