Which code segment should you use?
You write the following code segment to call a function from the Win32 Application Programming Interface (API) by using platform invoke.
string personName = “N?el”;
string msg = “welcome ” + personName + “to club”!;
bool rc = User32API.MessageBox(0, msg, personName, 0); You need to define a method prototype that can best marshal the string data.
