Operator Overload1. When the subscript operator is overloaded (array symbol): cannot be overloaded as a friend function, it must be a member function of a non-static class. Why 2. Overload + +, if:int A; ++a; + + when in front, what to

Introduction:Although not how to contact vb.net, but probably for VB6 still more understanding. The former is developed on the basis of the latter. Then came into contact with the C # programming language, initially did not care too much about her

Like Class A.public class A{public void Function (ref string pcref){You have to assign a value to the pcref, even if the assignment "" canPcref = "I returned a string";}}Then, in class B, call A's method functionBefore calling, assign an initial

Events are an important feature of C #. Events mainly involve publishers, subscribers, and event handlers.It is convenient to define events by using predefined delegate types in the. NET class library. After the publisher triggers the event, the
