Easy way to get hex from a string in .net

Question

I want to get hex from a string like this:

Color c = new Color();
c.A = Int32.Parse("0x7F"); 

What's the right method for this ?

Answer 1

If the hex string isn't known till runtime, then something like this:

c.A = Convert.ToInt32("0x7F", 16);

Or as a literal if the value is known at compile time:

    c.A = 0x7F;

Answer 2

With the Parse method, check the overload which allows NumberStyles. Reference http://msdn.microsoft.com/en-us/library/c09yxbyt.aspx

int bla = Int32.Parse("beef", NumberStyles.HexNumber);

Answer 3

Convert.ToInt32("hexvaluestring", 16); Should be enough.
