How to convert Platform::String to char*?

by

Here is a very simple way to do this in code w/o having to worry about buffer lengths. Only use this solution if you are certain you are dealing with ASCII:

Platform::String^ fooRT = "aoeu";
std::wstring fooW(fooRT->Begin());
std::string fooA(fooW.begin(), fooW.end());
const char* charStr = fooA.c_str();

Keep in mind that in this example, the char* is on the stack and will go away once it leaves scope
