1. avoid locking public objects. If the instance can be accessed by the public, the lock (this) problem occurs. If there is a class myclass, this class has a method that uses lock (this) to achieve mutual exclusion: 1 Public Class myclass 2

Identify the location of the largest element in the array using the rule and grouping policy. The problem itself is simple, and there are many more efficient implementation methods,This article aims to introduce the idea of Rule delivery and rule

A small feature, which has already been implemented. I used it in a project. I think it is necessary to record it and write it down. Code Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--> /*

Recently, static classes have encapsulated many things, so there are many studies on static classes. The following is the conclusion. Static variables are a public variable memory, which may conflict with each other.If it is a static method, it

First Note: posted on Mr. Li Jianzhong's website www.lijianzhong.com to encourage you to learn more. I received a letter from a recent C # training student. Although the student lacks skills in the past, he has a strong learning base and is

CLR via C # is a classic textbook about CLR. It has always been intended to read well, but has never been read. At the end of last year, I finally made up my mind to buy a paper CLR via C #. On New Year's Day, I went to my home to study in closed

To understand the C # garbage collection mechanism, let's first talk about the CLR (Common Language Runtime when a common language is running). It is a runtime environment like a Java Virtual Machine. Its core functions include memory

In this blog post, it may be difficult to say something. I was prepared to update it the day before yesterday, but I have been unable to find a proper statement for repeated consideration, I may not understand it very well. Therefore, in this blog

About two years of. Net experience, one year of BMC experience, as an electronic professional, is still in mind for C and C ++. Recently, when the project is idle, check windows programming and windows via C/C ++, and use C ++ to create and

1.Event principle: Before explaining the principles of an event, let's take an example as follows: 1. Start Vs and create a winform ApplicationProgramIn the form window, create a button. When you click this button, the message "you clicked me!"

It's just a little trick. Ajax has become an inevitable idea when it comes to calling the background C # method in front-end Js.Only the implementation details use Ajax 1.0 or ajaxpro.In fact, without Ajax, we can also easily use js to call the

In the preface, you should have a little understanding of the importance of delegation and events. Although we can still be vague, from my vernacular series, I will make these concepts easy to understand. First, let's talk about delegation first.
