entrust Delegate
        C# Medium Delegate Corresponding to C The pointer in , But it's different C A pointer in can point to a method , It can also point to variables , And you can do type conversion ,
C The pointer in is actually a memory address variable , It can operate memory directly , Through memory
Address direct access to variables , Direct call method .
         and C# Medium Delegate It's a strong type of , That is, when the delegate is declared, it has been specified
This variable can only point to a specific parameter , And the method of returning the value .
         Use delegate You can directly create a delegation type with any name , When the system is compiled
when , The system will automatically generate this type . You can use delegate void MyDelegate()
Method to create a delegation class , And use ILDASM.exe Observe its members . from ILDASM.exe
Can be seen in , It inherited System.MulticastDelegate class , And automatically generate BeginInvoke、EndInvoke、Invoke Three common methods .

        Invoke Method is the corresponding method used to synchronously call the delegate object , and BeginInvoke、EndInvoke Is used to call the corresponding method asynchronously .
