c# - How to continue executing code after calling ShowDialog()

Question

the Form.ShowDialog() method causes the code to be halted until the newly called form is closed. I need the code to continue running after the ShowDialog() method is called. I googled and read about using backgroundworker? But that is the first time i have heard of that and never used it before.

Form2 form2this = new Form2();
form2this.ShowDialog();
MessageBox.Show("Something");

This code gets executed after clicking a button, how can i still call ShowDialog to prevent the user from interacting with the main form but still allowing the main form to continue with its work?

Sorry if its been discussed but everything i found seems extremely difficult to perform such a simple task. I am actually surprised its not included in the SHowDialog method. for instance ShowDialog().Continue would be cool.

• If you just want the code to continue on instead of blocking until the popup is closed consider using Show instead of ShowDialog.

• If you have some action that you want to have the parent form doing while the child form is up, then yes, it could be appropriate to use a BackgroundWorker (or just manually starting a new Thread/Task). It would be helpful to know more about what that task is though. If you need to interact with the main form, or the child form, then that seems like trouble to me; if you just need to do some background task with no UI interaction then this is the right line of thought.

• Another possibility is that what you want to do really just should be something done in the child form, rather than the parent form.
