A console application or a command line interface or CLI is a method of interacting with a computer via a text terminal. Commands are entered as lines of text (that is, sequences of typed characters) from a keyboard, and output is also received as text -wikipedia.org

To create a new console application project with Visual Basic.NET, choose File - New - Project. On the next dialog that appears, select Visual Basic Projects from the Project Types treeview then select Console Application icon from the Templates listview. Fill the project detail such as name and location then hit OK. A new module named Module1 will be created after that.

Inside the newly created module, there is a Sub procedure called Main(). This is the startup object of your console application, where you write your program code.

We will create a simple VB.NET console application which may accepts CLI parameters separated by commas. Below is the line that initiated an array to hold the parameters passed to the application:

Lets say the name of your application is “myApp”. If you run it with this syntax below:

Then the arrArgs array will contains these element:

What you are going to do next with those values is up to you. Following is the Sub Main() full code you can use to test it:

That code will accept parrameters passed to the EXE then it will display the accepted parameters to the monitor.
