They are already numbers, a and b. :-)

Perhaps i can use that , if the relation between the character values and their numerical values is linear

Sergey Alexandrovich Kryukov 23-Jan-13 12:45pm

Linear, linear. You just don't explain it.

I think your idea is very helpful, the values of the letters in ascii code are sequential, many thanks my freind

Your questions are very difficult to decrypt. Looking at your other questions show a similar image.
It would help to get more useful answers if you try to pose the questions more precisely.
E.g. as Sergey already mentioned, a = 1 and b = 2 are not "characters". An you also do not answer to counter questions. Why? This is quite annoying.

Solution 3

Use int.Parse or int.TryParse, but instead of int use any numeric type you like and then see the description of these two methods in MSDN help. Depending on content of the character data, it succeeds or not. As simple as that.

I'm sorry bu this method only convert strings that represent numbers like "1" or "2" etc. Thanks for you support

You are welcome. I even think that you can accept if formally (green button).
Please understand that this is a way to go, because this method is universal, agnostic to implementation detail...

Wait a second. Who told you it "only converts..."?! Read again...

Thank you, Espen.

Solution 2

Create an enumeration for your values then look at this article, Tips about .NET Enums[^], to see how to convert from the string representation (your char) to the corresponding value (integer) and back again.
