In Delphi, there is a function StrToInt() that converts a string to an integer value; there is also IntToStr(), which does the reverse. These functions doesn't appear to be part of Oxygene, and I can't find a reference to something that can do that. How can it be done?

2Delphi Prism is a compiler. It does not contain a library like Delphi win32 does. When using Delphi Prism you can use the full range of .Net classes and methods in the .Net library. It is the same library that C# and VB.Net uses. You might want to read about the subject in C# books or on http://msdn.microsoft.com/en-us/library/ms229335.aspx – Lars Truijens Nov 09 '09 at 21:33

@Lars - That's not entirely accurate. Delphi Prism ships with a handful of DB connectivity components and design tools. So its not just a compiler. – Kenneth Cochran Jul 27 '10 at 16:56

You can use the Int32.Parse function
try this
function StrToInt(S: String): Integer;
begin
Result:=Int32.Parse(S);
end;
.Parse is pretty richly supported for multiple types.

3You can also use Int32.TryParse(S, out intVariable) which returns a boolean indicating whether parsing the string into an integer was successful. – Sebastian P.R. Gingter Nov 11 '09 at 16:49

RRUZ has the correct answer, but if you can't say good-bye to all the functions and classes you where used to in Delphi win32 you could take a look at ShineOn. It's an open source library written in Delphi Prism to port Delphi win32 functions and classes to .Net. Not surprisingly it also contains IntToStr and StrToInt.
