Just sorted out-functions for converting Chinese characters to PinYin abbreviations (C #)I found it on csdn and did not find a complete conversion function. I have sorted it out on the basis of my predecessors. The following projects may be used.

Using the webbrowser control is really convenient to implement, but it is less flexible than sending packets in a direct group. For a web game of the Three Kingdoms, webbrowser can theoretically achieve the desired function if it is used well (I

  I always believe that for a beginner, the technical trend in the IT field cannot catch up with and cannot catch up with it. I often see my DDMM throwing away textbooks and selling expensive big numbers such as C # and VB. Net, which makes me very

Origin and order This past weekend is very meaningful to me. First, I got a copy of "God throw the dice?" on Friday. A popular science book about quantum theory, which has been seen from Friday night, has been touched by the inconvenience of many

Till now, we have been using the simple = value assignment operator. In fact, there are other value assignment operators, and they are all very useful. Except the = Operator, all other value assignment operators work in a similar way. Like =,

In applications, we may need to implement shortcut keys such as Ctrl + C copy and Ctrl + V paste. This article briefly introduces its implementation and provides an implementation class. (1) create a class file named HotKey. cs. The Code is as

People who have studied mathematics know that Gaussian elimination method is used to solve linear equations. The algorithm is very simple, but the process is very complicated, this is why I cannot find a free and correct Gaussian elimination method

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 Management,

Understanding heap and stack is helpful for understanding memory management, garbage collection, errors and exceptions, debugging and logs in. NET. The garbage collection mechanism frees programmers from complicated memory management. Although the

We often use WebBrowser to perform automated tasks during web testing. In some web pages, IFrame is used to nest other pages. These pages may not be under the same domain name. In this case, cross-domain issues may occur and the IFrame elements

The bitwise operation is used to implement addition, that is, the computer performs binary operations. A 32-bit CPU can only represent the number within 32 bits. Here we use the one-digit addition, the following code does not consider carry. Copy
