Try to do less transformational actionWhat is the purpose of doing less transformational action? Obviously, it is to improve the stability of the program and improve the efficiency of the program execution.So, what are the ways of transformation?

Sometimes, it takes a random number to write a program. We can actually produce different random numbers each time we want, but the computer is not human, it needs to generate random numbers by the corresponding algorithm.1. Generate Random

Today review the C language type conversion and branching structure, C is a strong data type, and his grammar compiler is not as strict as other languages later, so we must pay attention to our own data type when using it. Type conversions are

What's the Commission? A delegate is a type-safe object that points to another method (or methods) that will be called later in the program. In layman's words, a delegate is an object that can refer to a method, and when a delegate is created,

The purpose of the extension method is to add a method to an existing type, such as the following code, which adds a method of turning into a shape for string strings.In this way, you can add some other methods to refine the code for many existing
