How to get hexadecimal number of a char?

Question

I have to develop a Windows Mobile C# app to compare chars and get the ascii code

This is my pseudocode:

    public void getAscii(char c) 
    {
        int ascii_n = c.GetAscii(); //or something that gives me the hexadec number
        //You know; a=97, b=98...

        if (ascii_n > 12 && ascii_n < 23)
        { 
            //code lines
        }
        else if (ascii_n > 24 && ascii_n < 55)
        {
            //more code lines
        }
    }

Any idea about how can I do it??

What do you want to do with non-ASCII characters, that is, Unicode characters? — John Saunders, Mar 24 '14 at 23:53
Just so you know, this functionality is already available in the framework in the form of `Char.IsUpper`, `Char.IsLower` and `Char.IsDigit`. — User 12345678, Mar 25 '14 at 00:04

You don't need an hex representation of a char, just a conversion to an integer could be enough

char c = '\n';
int ascii_n = (int)c;
Console.WriteLine(ascii_n);   // = 10

also for char higher than 255

char c = '∙';
int a = (int)c;
Console.WriteLine(a);   // = 8729

Aren't both examples technically Unicode? Just that ASCII has the same values as Unicode? – User 12345678 Mar 25 '14 at 00:01
Yes they are both unicode, it is just to show that it works also for values higher than 255 – Steve Mar 25 '14 at 00:02
