C#

There are many ways to execute a function in another thread. Here we discuss the use of the BeginInvoke method of delegate. The advantage of this method is that the function is called in another thread, and there is no need to spend too much. The

Thread Synchronization is inevitable when writing multi-threaded programs. What is thread synchronization? For example, if A company has A variable that records the salary count of someone T = 100, there are two supervisors A and B (that is, the

C # three methods for determining null strings:String a = "";1. if (a = "")2. if (a = String. Empty)3. if (a. Length = 0)The three methods are equivalent, so which method has the highest performance? I will illustrate the problem with an

 Chapter 1 C ++'s learning finally started, and I was very excited in my heart. in the previous chapter, I learned to define some variables and then made some simple operations on these variables, and some of these simple operations are associated

In the object-oriented "Closed encapsulation" development principle, we always advocate encapsulating independent functions in a class! However, from Visual Studio 2005 development, the system provides a branch-class development method that has been

The previous section describes how to use GetTickCount () to control time slice switching. However, MS. net framework also provides the PerformanceCounter object to obtain various performance data of system resources. With this PerformanceCounter

  Today I wrote a tool to convert object classes to XML, and convert XML to corresponding object classes.   The Code is as follows:   XML Conversion class   Using System; Using System. Collections. Generic; Using System. Linq; Using System.

  When sending multi-value cookies, you can use the following method to set multi-value cookies.   C # code System. Net. HttpWebRequest r = System. Net. HttpWebRequest. Create ("http://www.mengxianhui.com: 8081/B. aspx") as System. Net.

In some cases, we often need to simulate browser operations, such as simulated voting, simulated clicks, or Web game plug-ins. The encapsulated WebClient in C # can implement Http Post and Get in some scenarios where the requirements are not counted.

  C # Is a type-safe programming language (all expressions can be parsed into an instance of a certain type. In the code generated by the compiler, only operations of this type are executed ), compared with non-type security languages, the

  When talking about threads, we should be familiar with them. Similar to him, there is also a Process concept ). First, familiarize yourself with their concepts and relationships. What is a process? When a program starts to run, it is a process,

  Static void Main () { String path = @ "D: \ Practise \ IO \ Compress ";   String deCompressPath = @ "D: \ Practise \ IO \ DeCompress ";   DirectoryInfo dir = new DirectoryInfo (path ); Foreach (FileInfo fi in dir. GetFiles ()) { Compress (fi

  When I developed a small log program and saved the log file to HTML, operations on the file are inevitable. I wrote a file operation class HtmlOption for all HTML operations.   Using System;   Using System. Collections. Generic;   Using System.

During Winform development, some configuration information is inevitably written to the APP. in the CONFIG file, after the program is generated, the APP. CONFIG is changed to A file with the program name + CONFIG. For example, if the program name is

C # asynchronous operations are often used during development. In particular, many IO-related accesses under Windows phone and Silverlight are asynchronous.Standard Asynchronous methods are usually a pair of methods for in [Invoke] and End [Invoke],

Although AcitecX is an old and classic application technology, AcitecX is still so practical in today's ever-changing technological developments. Without it, you cannot find a more suitable technology to replace it. This is not the case. Recently,
