What is the basic structure of the C# console application

This article mainly explains "what is the basic structure of the C# console application". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought. Let's study and learn what the basic structure of the C# console application is.

Let's take a look at the example of a C# console application (ConsoleApplication1) and examine its structure. The code is as follows:

Using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication1 {class Program {static void Main (string [] args) {/ / Output text to the screen. Console.WriteLine ("The first app in Beginning C # Programming!"); Console.ReadKey ();}

You can immediately see that all the grammatical elements discussed in the previous section are here. There are semicolons, curly braces, comments, and appropriate indentation.

For now, the most important part of the code is as follows:

Static void Main (string [] args) {/ / Output text to the screen. Console.WriteLine ("The first app in Beginning C # Programming!"); Console.ReadKey ();}

When you run the C# console application, you run this code, or more accurately, the block of code in curly braces. As mentioned earlier, comment lines do nothing and include them only for brevity. The other two lines of code output some text in the console window and wait for a response. But at present, we do not need to care about its specific mechanism.

Note here how to implement code highlighting, which, while important for Windows applications, is a very useful feature. To achieve this, you need to use the # region and # endregion keywords to define the beginning and end of areas of code that can be expanded and contracted. For example, you can modify the generated code for ConsoleApplication1, as follows:

# region Using directives using System; using System.Collections.Generic; using System.Text; # endregion

Note:

Any keyword that starts with # is actually a preprocessing instruction and is not strictly a C # keyword. Except for the # region and # endregion keywords described here, the other keywords are quite complex and professional in usage.
