Convert char to int in C#

Question

I have a char in c#:

char foo = \'2\';

Now I want to get the 2 into an int. I find that Convert.ToInt32 returns the actual decimal value o

Answer 1

This will convert it to an int:

char foo = '2';
int bar = foo - '0';

This works because each character is internally represented by a number. The characters '0' to '9' are represented by consecutive numbers, so finding the difference between the characters '0' and '2' results in the number 2.
