Mediator Mode (mediator): Uses a Mediation object to encapsulate a series of object interactions. The mediator makes the objects do not need to explicitly interact with the reference, which makes the coupling loose, and can independently change the

Observer Mode (OBSERVER): Defines a one-to-many dependency that allows multiple observer objects to listen to a principal object at the same time. This subject object notifies all observer objects when the state changes, enabling them to

Abstract Factory: Provides an interface to create a series of related or interdependent objects without specifying their specific classes. Pattern implementation: [Code]//create productaclass producta{public:virtual void Show () = 0;}; Class

Adapter mode (Adapter): Transforms the interface of one class into another interface that the customer wants. The adapter mode makes it possible for those classes that would otherwise not work together because of incompatible interfaces to work

Memo Mode (Memento): captures the internal state of an object without compromising encapsulation, and saves the state outside that object. The object can then be restored to its previously saved state. Pattern implementation: [Code]struct

Enjoy meta mode (Flyweight): Use sharing technology to effectively support a large number of fine-grained objects. Four role classes: Flyweight: The superclass or interface of all the specific classes of the class, through which the flyweight can

Factory method Mode (Factory): Defines an interface for creating an object that allows subclasses to instantiate which class, and the factory method defers the instantiation of a class to its subclasses. The difference from a simple factory: The

Appearance mode (facade): Provides a consistent interface for a set of interfaces in a subsystem that defines a high-level interface that makes this subsystem easier to use. Two major roles: Appearance class facade: Know which subsystem classes

The transformation of the JSON string into a C # object is implemented here using the Atrribute method. Because of functional limitations, this version is only for JSON strings, such as "response": "Hello", "id": 21231513, "result": +, "msg": "OK.";

public void ProcessRequest (HttpContext context) { string elxstr = " 111222 "; Context. Response.Clear (); Context. Response.Buffer = true; Context. Response.appendheader ("Content-disposition", "attachment;filename=" +

This example describes a C # implementation of a method that exports data to Word or Excel. Share to everyone for your reference. Specific as follows void Outtoword () {if (DataGridView1.Rows.Count >= 1) {String tempstr = ""; Stream MyStream;

Code: public void ProcessRequest (HttpContext context) {context. Response.ContentType = "Image/jpeg";//Create a bitmap and give the width of the specified border using (Image img=new Bitmap (80,25)) {//Create painter object, draw string using in

Because the work needs to study the JS Ajax, the following is the result. There are three main parts: First, JS part of the Friendship notice in the JS section of the $ ("#btn_login") in the return false; This can prevent the rotation of the server

Ajaxloadprogressform.aspx: loading ... Getgridviewbyconditionform.aspx: protected void Page_Load (object sender, EventArgs e) {if (request["id"]! = null) {SqlConnection conn=null; SqlCommand cmd = null; SqlDataAdapter adapter = null;

Whether it is jquery or Ajax in today's discussion has been very backward, there is a lot of information on the Internet, but still a lot of novices are very confused. This article is the simplest way for beginners to demonstrate how to use jquery

C # Study Notes 3, 1.Although not necessary, we generally recommend that you put each class in its own file and name the file with the class name, you can easily find the code that defines a specific class.   2.If you do not add an access token for
