Take you to create your first C program (recommended Collection)

Knowing about console applications is usually knowing C# The first step in the application , It is a similar DOS The program of input and output in the interface of , It's learning C# The basic syntax of the program is the most convenient program .

Next, let's introduce how to create a console application .

Creating a console application is very simple , Choose in turn “ file ” One “ newly build ” One “ project ” command , The dialog box as shown in the following figure will pop up .

Choose among them “ Console Application ” Options , And set a name for the project 、 Location and solution name , single click “ determine ” Button to create a console application , The effect is shown below .
Note that the solution name is not necessarily the same as the project name , Multiple projects are allowed in the same solution .

As can be seen from the interface shown in the figure above, a new interface named Solution Solutions for , And in this solution, we created a project named Test Console application for .

stay Test The application contains a file called Program.cs Class files , The code in this file is shown in the figure below .

In this code, the 11 Go to the first place 13 Line is Main Method ,Main Method is a special method , And there can only be one in each class , Just write the code to Main In the method , After the project runs Main The code in the method will execute .

Apply on the console The method of outputting content in the console interface of the program is as follows .

Console.Write(); // Output content to the console interface without line break
Console.WriteLine(); // Line feed output content to the console interface
Now use the console application to output to the console “ first C# Program ” and “ This is a console application ”, The code for the implementation is as follows .

namespace test
{
    
    class Program
    {
    
        static void Main(string[] args)
        {
    
            Console.WriteLine(" first  C#  Program ");
            Console.WriteLine(" This is the first console program ");
        }
    }
}

Press Ctrl+F5 Key combinations run programs , The effect is shown below .
