In the past, the singleton used in the project has always been the simplest C # method. It is Thread Safe, and only one instance can be used in multiple threads. The Code is as follows: Public sealed class Singleton{Public static readonly Singleton

Question: there are multiple assessment results on one page, such as courtesy, expression skills, telephone control, listening skills, and emotional control. If you don't want to assess, there are multiple assessment criteria, such: such as rating,

Some people will encounter some small problems during the interview. Although these problems are small, they can display your past work conditions and the status of programming.The following example shows how to remove duplicates from arrays. If you

First run the Code: [Csharp]Public partial class MainWindow: Window{Public MainWindow (){InitializeComponent ();Thread t = new Thread (new ParameterizedThreadStart (threadTest ));T. Start (@ "C: \ Users \ Public \ Pictures \ Sample Pictures \

The question is simple. For example, there are two sets. List listA = new List {"a", "B", "c", "d", "e "};List listB = new List {"a", "B", "f "}; You need to find the elements that exist in listA and do not exist in listB. Method 1: List B =

/// /// Find the node whose Text is nodeText from the child node of the specified Node/// /// Text value of the node to be searched /// query all child nodes of kNode /// Private TreeNode FindNode (string nodeText, TreeNode kNode){Foreach

Some time ago, I have been analyzing the case about dynamic, but there are only some vague concepts about dynamic and DLR. I have recently studied this part well and I am a little bit confused.What is dynamic and what is Dynamic Language

Object copy is often used in programming. The following provides a method for object deep copy, which is quite good. [Csharp]Public object Copy (this object obj){Object targetDeepCopyObj;Type targetType = obj. GetType ();// Value TypeIf (targetType.

Overview and conceptsC # supports code execution in parallel through multiple threads. A thread has its own execution path and can run concurrently with other threads. A c # program starts with a single thread. This single thread is automatically

Program shutdown is very exquisite. If the processing is not good, the software will be turned on and off continuously. When the software is started several times, the program will crash. Or program exit is slow. Details determine the success or

Recently, during the development project, you need to obtain the IP address area used for statistical analysis. After some materials, I wrote a test program and quickly completed this function. Now, let's share my implementation methods. If you have
