In this example, the code begins by checking to see if any arguments were passed to the Main function if none were, the user is notified and the Main function is exited.ДЄfter making sure that we have an argument to process, the application prints a title out to the screen, two variables are then created and initialized one will contain the value passed into the Main function as an argument, the second will contain the value obtained by squaring the orginal value. display indication of invalid input from command lineД¬onsole.WriteLine( Environment.NewLine + 'Invalid Input' + SquaredValue = orginalValue * orginalValue Д¬onvert.ToString(orginalValue) + ' Squared = ' + Convert.ToString(squaredValue) + OrginalValue = int.Parse(args.ToString()) //first argument only The code used to perform these actions is as follows:Д¬onsole.WriteLine( 'No arguments submitted') Д¬onsole.WriteLine( 'Squared Argument' + Environment.NewLine) In this example, an integer value is passed to the Main function the application will attempt to process the first argument in the list by squaring the value submitted and then displaying that value in the console. In the sample, the application is set up to process the first argument in the argument list any additional arguments passed in are simply ignored.

You may, however, process anything passed as an argument, not just file paths. If you wanted to do something like open and process a file on initialization, you may wish to allow the application to accept a file path as an argument and process the associated file when the application is started. The Main function accepts a string array as an argument list and you may either ignore or process any or all of the list as you see fit.

Command line arguments are processed in the Main function of the application and it does not matter whether or not the application is a Windows application or a console mode application. The first example, SingleCLA, demonstrates an approach to processing a single command line argument.

All examples were written using Visual Studio 2005 and are in C# the same code could also be used in earlier versions of Visual Studio.Д¬ode Example 1: Processing Single Command Line Arguments. You may open and examine each of the projects if you wish, however, the code is quite simple and will be described in the following sections of this document. A console mode application that processes a variable number of arguments in a manner consistent with processing a key-value pair. A console mode application that processes multiple command line arguments A console mode application that processes a single command line argument There are three example projects included with this article the examples include: Processing Multiple Command Line Arguments The additional examples provided illustrate approaches to processing single arguments and processing a variable number of arguments.ДЇigure 1. The example provided illustrates processing a variable number or command line arguments and further describes an approach to processing arguments using a key-value pair for each item processed. This article describes an approach to processing multiple command line arguments.
