Tips (7): Agent & event, and Agent

Proxy delegate:

Object reference points to a specific type of object.

The proxy points to a specific type of method.

Proxy Step 4:

 

Class Program

{

// Define the frist proxy

Public delegate void first (int I );

// Main function, main Entry

Static void Main (string [] args)

{

// Create a first-type reference

First MyDelegate = null;

// Create a proxy reference pointing to the show Method

MyDelegate + = new first (show );

// Call the show method through proxy reference

MyDelegate (666 );

Console. ReadKey ();

}

// Show Method

Public static void show (int I)

{

Console. WriteLine (I. ToString ());

}

}

Class Program

{

// Define the frist proxy

Public delegate void first (int I );

// Main function, main Entry

Static void Main (string [] args)

{

// Create a first-type reference

First MyDelegate = null;

// Create a proxy reference pointing to the show Method

MyDelegate + = new first (show );

// Call the show method through proxy reference

Diao( 666, MyDelegate );

Console. ReadKey ();

}

// Show Method

Public static void show (int I)

{

Console. WriteLine (I. ToString ());

}

//

Public static void diao (int I, first dele)

{

Dele (I );

}

}

 

Event:

// Define the EventDelegate proxy

Public delegate void EventDelegate ();

Class Program

{

// Main function, main Entry

Static void Main (string [] args)

{

// Instantiate ClockTimer

ClockTimer clockTimer = new ClockTimer ();

// Add the OnClockTimer method to MyEvent

ClockTimer. MyEvent + = new EventDelegate (OnClockTimer );

// Execute the show method of the clickTimer object

ClockTimer. show ();

Console. ReadLine ();

}

// Acceptance Method

Public static void OnClockTimer ()

{

Console. WriteLine ("receive clock event ");

}

}

// Event generation class

Public class ClockTimer

{

// Define an event)

Public event EventDelegate MyEvent;

// Event Generation Method

Public void show ()

{

For (int I = 0; I <1000; I ++)

{

// Generate an event

MyEvent ();

// Sleep for 1 second

Thread. Sleep (1000); // System. Threading;

}

}

}

Masters, the above is my understanding of event and delegate. If something is wrong, please help me to point it out. Thank you!
