int i1 = int.parse(s1.SubString(0,2));
int i2 = int.parse(s2.SubString(0,2));

int i1 = Convert.ToInt32(s1.substring(0,2));

And the same for i2 of course, obviously not great using hard-coded index of 2, but you could specify that in some other way through user input or whatever?

Simple:

int i1 = Convert.ToInt32(s1.Substring(0, 2));
int i2 = Convert.ToInt32(s2.Substring(0, 2));

You'll have to add various checks, though (say, what happens if the length of either string is less than 2? or if they contain something other than digits?)
