It's like this: How to convert from System::String* to Char* in Visual C++

System::String ^ str = "Hello world\n";

//method 1
pin_ptr str1 = PtrToStringChars(str);
wprintf(str1);  

//method 2
char* str2 = (char*)Marshal::StringToHGlobalAnsi(str).ToPointer();
printf(str2);
Marshal::FreeHGlobal((IntPtr)str2);

//method 3
CString str3(str); 
wprintf(str3);

//method 4
#if _MSC_VER > 1499 // Visual C++ 2008 only
marshal_context ^ context = gcnew marshal_context();
const char* str4 = context->marshal_as(str);
puts(str4);
delete context;
#endif
