How do I run a Visual Studio C# program with command line arguments?

Question

I have a very basic Visual Studio console app:

using System;

namespace BasicApp
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(args.Length);
        }
    }
}

I can run it just fine from inside Visual Studio by clicking the green triangle "Run" button, but I also want to be able to run it from the command line and pass it some arguments. I'm a little confused by the file structure of Visual Studio projects and I don't know too much about how compiling works. What do I need to type into the command line in order to make it run?

Answer 1

If you want to run the program with command line parameters in Visual Studio, you can go to the main menu and follow below order:

1. Project
2. BasicApp Properties
3. Debug
4. Start Options
5. Command line arguments:

After inputting your command line arguments there, the arguments will be passed to Visual Studio debugger.

Please see the attached screenshot.

Answer 2

1. Under the "Build" tab, click "Build Solution".
2. Using command line, navigate to MyProject\MyProject\bin\Debug\netcoreapp3.0\.
3. From inside the netcoreapp3.0 directory, simply execute MyProject.exe from the command line.
