Arguments to String::Format

[Kevin Burton]

I have the following code:

Trace::WriteLine(String::Format(S"{0} {1} {2} {3}",
Marshal:trToStringAnsi(s->Line1),
Marshal:trToStringAnsi(s->Line2),
Marshal:trToStringAnsi(s->Line3),
Marshal:trToStringAnsi(s->Line4)));

But the compiler complains that there is no overload for
String::Format that takes 5 arguments. With C# this is
rather simple. I am not sure how to proceed with C++. Any
suggestions?

Thank you.

Kevin

The C# compiler knowns the ParamArrayAttribute and therefor can convert the
4 parameters to an array.
The managed C++ does not know (or cannot handle) this attribute, therefor
you have to do it by hand.
Maybe in a next version the managed C++ compiler is also a little bit more
intelligent...

Do you need a memory-leak finder ?
