Call another app with parameters in C#

Question

Hello. I would like to start a new app in C#, but I would like to pass a variable to this app. How should I start the app with the variable, or how should the app receive the variable? Thank you.

Answer 1

You cant start another app from your app.

The only way would be to have the user start both apps and pass data between them via a file.

Nigel's close.

You cannot directly start another app from your app, but you can launch a URI and have it open in the default handler for that URI. You can leverage this by having your app define a custom protocol which accepts the arguments you want to pass.

The caveats are that the user gets to choose the default handler, so your app cannot depend on launching a specific app, and your app won't pass certification if it has a strong dependency on an external app.
