Question

In C#, I would like to create a function (method) that has the following behavior:

1. When called, create and show a form.
2. Wait for the user to enter or select a value on the form.
3. Return the selected value.

Is there a concise, readable way to implement this function?

Answer 1

If you are looking for dialog functionality, WPF and WinForms both support this. You simply invoke ShowDialog() on the window / form being shown. This is a blocking call, so until you close the shown dialog, you won’t return processing to the calling window.

To return values from this call, simply make properties on your Form / Window, and then inspect those after ShowDialog().
