[TUT] Passing Arguments To A Console Application - ubbelol - Jun 18, 2010

Hey, i've had a few requests on making a tutorial on how to pass arguments on a VB.NET/C# console application so here we go:

It's actually ALOT more simple than it might sound, all you have to do is creating an string array that splits the arguments inputted.

Alright so here's the full code:

Code 
Sub Main()

  Dim strArray() As String = Command.Split("-")

  If Not strArray.Length < 1 Then

    For i = 0 To strArray.Length - 1

    Console.WriteLine(strArray(i).Trim())

    Next

  End If

  Console.ReadLine()

    End Sub

Now lets break it down into lines

The first line:

Code 
Dim strArray() As String = Command.Split("-")

What that does is basically split the input that users type in by the char "-". You can change the char to whatever you want your args to be splitted with, example if you use "/" as a split char you enter args like:

Code 
C:\path.exe /arg1 /arg2 /arg3

The second line:

Code 
If Not strArray.Length < 1 Then

This simply tells the program to only execute the following code IF the strArray length (amouns of args inputted) is not less 1.

On to third:

Code 
For i = 0 To strArray.Length - 1

Here we create a loop wich goes from 0 to the length of strArrays length (amouns of args inputted) and for each argument we execute the following code:

Code 
Console.WriteLine(strArray(i).Trim())

This outputs the current argument in strArray, strArray(0) would be "arg1" and strArray(1) would be "arg2" etc, i think you get the point.

The Trim() command removes any spaces in the start and end of the current argument so you won't get arguments like " arg1 " wich can be hard to use later on in the program.

And the last

Code 
Console.ReadLine

Simply waits for the user to input anything, this is just to pause the window and not making it close instantly.

Heres a little video example of the console in action:
