如何将命令行开关添加到 VB.NET WinForms 应用程序（从 CMD 运行时）？

Question

I am creating a GUI-based application (VB.NET); I want it to have switches (such as -s , -r , -a , etc.) when run from the command line and not display the GUI.

I have already tried a plethora of methods, but they do not work, even the ones from Microsoft themselves.

Please help me. I have been researching for a day now.

Answer 1

Set your startup form to .visible = false .

Then in the Form_Load event:

' Loop through the passed arguments
For Each argument As String In My.Application.CommandLineArgs

 ' Do stuff. i.e.:

 if argument = "-s" then
    ' Do something
 End if

 if argument = "-r" then
    ' Do something
 End if

 if argument = "-a" then
    ' Make the form visible
    Me.Visible = True
 End if

Next

Also, if you're planning to never use the GUI, just make a console app instead of a winforms app.
