How to retrun a character with ascii code

How to retrun a character with ascii code?
It is useChr(65) return 'A' in VB.NET.
What is the equivalent function in C#?

Hi Ad,

char[] characters = System.Text.Encoding.ASCII.GetChars(new byte[] {65});

Yes, looks quite cumbersome and I wonder myself why there is no overload for
a single character (or was I just too lazy to dig MSDN enough? ;-)

Why not Convert.ToChar(65) ?

char c = (char) 65;

works as well, though I consider it less readable.

Hallo Oskar,

I think Convert.ToChar as well as (char)65 assume the Unicode encoding,
while the author has explicitly mentioned the ASCII one.
Yes, the character codes of the capital 'A' are the same in both of the
encodings, but this, in general, might be not true for other character codes
and other encodings.

AFAIK the first 128 Unicode characters are the same as the
ASCII characters (except an extra leading zero byte).

So as long as you don't use values above 127 nothing
can go wrong. Right?

For every character which has an ASCII code, it's the same in UNICODE
(expanded to 16-bits)

Interesting read on the subject of character encoding:
