Hello,
I must present integers as a ASCII chars.
For instance for num 65 -> str1 "A".
int num = 65;
string str1 = String.Format(" {0:??}",num);
Mentioned problem cannot be solved with Encoding.ASCII. .. and others, because of the fact that I use specified "C# like" environment with only String.Format method for that.
I would be grateful for Your help.
Thanks...
