Reading Command line arguments in VB.NET

I will show you how to make a program which reads the Command line arguments from a program, it's pretty easy if you know how to do it

First we declares a ReadOnlyCollection to store the value from our commandline.

Code:

        Dim CommandLineArgs As System.Collections.ObjectModel.ReadOnlyCollection(Of String) = My.Application.CommandLineArgs

The to get them one by one it's just to refer to its index, in the example below a messagebox will pop up with the arguments one by one.

Code:

        For i As Integer = 0 To CommandLineArgs.Count - 1
            MessageBox.Show(CommandLineArgs(i))
        Next

This was actually all the code but before publishing you need to remember to uncheck the "use .deploy file extension" checkbox:

Now after publishing you will get the .exe file. If you create a shortcut to this .exe file you can add command line arguments to it as shown in the image below:

Our program can now read these argument and one messagebox showing "Argument1" will be shown and then one showing "Argument2".

That was it. Hope you liked it
