int->String:

AsString(x)

BTW, AsString is the "standard" function, it is implemented for many types. Moreover, templated

operator<<(String&, T)

and

operator<<(Stream&, T)

are implemented to use AsString, so in most cases, when putting things together, you do not need to care and just put any type on the right side of "<<":

String r; // or e.g. FileOut r;
int i;
Date d;
r << "The number is: " << i << " and the date is: " << d;

String->int:

Well, you can use c library atoi for simple cases. If you are about to have Null option for the empty string, you can use StrIntValue function.

However, in most cases, this is the part of wider text parsing code and that domain is completely ruled by CParser - simple, but extremely useful lexical parser.
