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

Has anyone considered using int.Parse() and int.TryParse() like this

int bar = int.Parse(foo.ToString());

Even better like this

int bar;
if (!int.TryParse(foo.ToString(), out bar))
{
    //Do something to correct the problem
}

It's a lot safer and less error prone

Answer 2

The real way is:

int theNameOfYourInt = (int).Char.GetNumericValue(theNameOfYourChar);

"theNameOfYourInt" - the int you want your char to be transformed to.

"theNameOfYourChar" - The Char you want to be used so it will be transformed into an int.

Leave everything else be.
