using <mscorlib.dll>

using namespace System;
using namespace System::IO;

int main() {
    // Make a reference to a directory.
    DirectoryInfo* di = new DirectoryInfo(S"c:\\");

    // Get a reference to each file in that directory.
    FileInfo* fiArr[] = di->GetFiles();

    // Display the names of the files.
    Collections::IEnumerator* myEnum = fiArr->GetEnumerator();
    while (myEnum->MoveNext()) {
        FileInfo* fri = __try_cast<FileInfo*>(myEnum->Current);
        Console::WriteLine(fri->Name);
    }
}

versucht jedoch scheint dies unter MFC nicht zu funktionieren.
Diese drei Zeilen geben einen Fehler beim Compilieren:
