Basic idea: An array is the most commonly used data structure that is stored continuously in memory, can be statically initialized (int a[2]={1,2}), and can be dynamically initialized with malloc ().The difficulty is that when the array is deleted

1. A delegate is a type-safe callback function that takes a method as a method parameter. Delegates can register multiple methods; A delegate is a MulticastDelegate class that can be assigned by = assignment, + = Add methods (object methods and

A delegate in C # is similar to a special pointer in C + +: A pointer to a function. By defining pointers to functions, we have the flexibility to invoke multiple functions in a program, assuming that the return type and parameter list of these
