+how to C# convert value to ascii ?

[Kate77]

Hi,
Im trying to build simple encryption,
I use
char d="a"
int intASC = System.Convert. ToInt32(d);

to convert it, and play with it,
now I want to change it (d) back for the original ascii value ("a"),
how do I do that ?

Do you mean you want to convert it from the ascii value to the char value?


[CODE=cpp] char x = Convert.ToChar( intASC);[/CODE]

PS: From your code that you gave, you should recieve a compilation error.
[CODE=cpp]char d = 'a'; //d is a char not a string[/CODE]
cheers

Sorry if I was not clear,
I have the following code:

class encrypt
{
public string enkrypt(string enc)
{

char[] thechars = enc.ToCharArray ();
string tata = "";
foreach (char d in thechars)
{
int intASC = System.Convert. ToInt32(d);
tata = intASC.ToString ();
}

return (tata);

}
}

now, when I call it, I get the value in this case 97.
encrypt enc = new encrypt();
MessageBox.Show (enc.enkrypt("A "));

what I am looking for now is a function that will do the opposite of
int intASC = System.Convert. ToInt32(d);

I want to take 97 and translate it to A ,
I am sure it is simple so forgive me if it sounds like stupid question.

Thanks,
-Kate

That is going to be tough, especially with no index.
your ascii values could be from a single digit to 3 digits long
so the string 167 could be interpreted in a lot of different ways.

Guess we need to come up with something better

Consider this:

char myc = 'a';
int myint = (int)myc;
//now myint will = 97 (the ascii value)
myint++;//make myint=98;
char myreturnc= (char)myint;
//now myreturnc='b'

its working!!
thank you,
sorry for the questions,
it just seems that unlike php finding how to do the simple things in C#
is very difficult.

Hehe, but if you know java, C# can be done in your sleep.
