For XML, I think everyone knows it well. I don't need to bother to describe what it is. I think XML will surely shine in the future of Web development, XML is a scalable markup language, which allows enterprises to develop their own data formats,

C # users often ask two questions: "Why should I write additional code to use features built in Windows? Why can't I complete this task for me without relevant content in the framework ?" When the Framework Team built their. NET part, they evaluated

String is the most basic data type in a variety of programming languages. It has been overwhelmed by other classes for a long time and is often disassociated (Substring, Split), torn (Join )... Now the string is about to turn over and make a

In development, we often encounter thread examples. If a background operation is time-consuming, we can start a thread to execute that time-consuming operation, and the program continues to execute. In some cases, synchronization and collaboration
