C # is especially good for building spider programs because it has built-in HTTP access and multithreading capabilities that are critical to spider programs. The following are the key issues to be addressed in constructing a spider program:

Making irregular forms involves the invocation of APIs and a lot of programming, which is a very complicated matter. Below we can use Borland C # Builder to easily implement an irregular form, with an example to describe its production process.
I.
In an application, there are times when users want to drag data from one control to another, which requires drag-and-drop technology.
Program Development Steps:
(1) Create a new form, add two label controls and two TextBox controls to the form,
Ref is the address of the pass parameter, out is the return value, the two have some similarities, but there are different points.
You must assign a value to a variable before you use Ref.
The Out function empties the variable, even if the
Intention
Enables multiple objects to have the opportunity to process the request, thus avoiding the coupling between the sender and the recipient of the request. Connect the objects into a chain and pass the request along this chain until an
Intention
Allows an object to change its behavior when its internal state changes. The object appears to modify its class.

Intention
Dynamically add some additional responsibilities to an object. Decorator mode is more flexible than generating subclasses in terms of adding functionality.

Intention
The use of sharing technology to effectively support a large number of fine-grained objects.
Scene
There are usually a large number of fine-grained objects in a system or framework-level software system that is relatively low-level.
Some time ago because the project needs, made a class for the sorting of the array, by the way the previous learned several sorting algorithms in C # implementation. C # Some of the mechanisms to explain the algorithm is implemented. Before reading

Train of thought: To do a network phone, basically follow the following steps
1, one side real-time recording, converts the analog signal into the digital signal;
2, the sound real-time compression;
3, through the network protocol to the

Implementation of this function in C + + is very simple, there are many classic examples can be achieved, in C # There are many problems will occur.

When learning a language, if there is no good understanding of its event handling mechanism, it is not well. I've been learning Java and C # for some time. In their plethora of similarities and even similarities, a very different event-handling
To construct an event for a class, you must declare an delegate type field with event, such as:
Puclic CALSS test{Public delegate EventHandler (object sender, EventArgs e); An event declared to be a delegate type;}
Then you specify the name of an
Classes are actually templates that create objects, each of which contains data and provides methods for processing and accessing the data. The class defines what data and functionality each object can contain, but the class itself cannot contain dat
