Command Line Arguments in C#

Article

In C# we can define two types of classes, one that has a Main() method and another without a Main() method. When we define a class with a Main() method, it is the entry point of our executable program for the application. The second type of class is used to build a class library for building application features.

1. Create a Console Application

Go to "File" -> "New" -> "Project...". The "New Project" window will appear, as in:

Click on the "OK" button and create a project with a solution.

2. Main Method

The Main() method is an entry point for execution program. Each execution program contains at least one Main() method. In our project default a Program class creates in Program.cs file.

3. Create Executable Program

The following Program is an executable program that is showing arguments on command.

using System;
namespace CommandLineApplication
{
    class Program
    {
  static void Main(string[] args)
        {
            for (int i = 0; i < args.Length; i++)
            {
                Console.WriteLine("Arguments Values are {0}", args[i]);
            }
            Console.Read();
        }
    }
}
