This article mainly introduces what the general structure of the C# program is, and it has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article.

A C # program consists of one or more files. Each file contains zero or more namespaces. A namespace contains classes, structures, interfaces, enumerations, delegates, and other types or other namespaces. The following example is a C# program backbone that contains all of these elements.

/ / A skeleton of a C# programusing System;// Your program starts here:Console.WriteLine ("Hello world!"); namespace YourNamespace {class YourClass {} struct YourStruct {} interface IYourInterface {} delegate int YourDelegate (); enum YourEnum {} namespace YourNestedNamespace {struct YourStruct {}}

The previous example uses the top-level statement as the entry point for the program. This feature has been added in C# 9. Before C # 9, the entry point was a static method called Main

As shown in the following example:

/ / A skeleton of a C# programusing System;namespace YourNamespace {class YourClass {} struct YourStruct {} interface IYourInterface {} delegate int YourDelegate (); enum YourEnum {} namespace YourNestedNamespace {struct YourStruct {} class Program {static void Main (string [] args) {/ / Your program starts here... Console.WriteLine ("Hello world!");} Thank you for reading this article carefully. I hope the article "what is the general structure of C# programs" shared by the editor will be helpful to you. At the same time, I hope you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
