The indexer allows you to easily use the Array (or set) members in the class: Using system; Class myclass {private float [] FS = new float [3] {1.1f, 2.2f, 3.3f};/* attribute */Public int length {get {return FS. length ;}set {FS = new float

I have always wanted to learn plug-in programming. The main reason is that my current customer needs are changing. If I integrate all the functions into an execution file, it is inconvenient to modify and upgrade, to use plug-in programming, you

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/--> /*

I was not prepared to study C # at first, but after graduation, I was scraped over by the financial tsunami. I remember that I started to look for a job before graduation. Fortunately, I didn't know anything about it, and I was very diligent, so I

1. fromhtml indicates the HTML color string of the fromhtml to be restored, and the fromhtml is dimmed.Public static color fromhtml (string htmlcolor ); Use: system. Drawing. Color c = system. Drawing. colortranslator. fromhtml ("# c37e00 "); 2.

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

// Calculate the number of weeks of the year based on the year Public Static Int Getweekcountofyear ( Int Stryear){Datetime firstday = datetime. parse (stryear. tostring () + " -01-01 " ); Int Weekoffirstday = convert. toint32 (firstday.

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

First of all, I would like to explain that although there is such a bad mentality (such as a Chinese technical book), Chinese technicians still like to share and teach others, my personal feelings are the opposite of those of my friends I saw in the

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

The lock keyword can be used to ensureCodeThe block is running without being interrupted by other threads. This is achieved by obtaining mutex locks for a given object during the code block operation. First, define the account class as follows:
