How to display a message box in C# as system modal?

Question

How to display a message box in C# as system modal, something like vbModal in Visual Basic 6?

Answer 1

Are you talking about message boxes, or standard forms? If you're talking about standard forms, the easiest .NET equivalent of vbModal is the ShowDialog method of System.Windows.Forms.Form. So, rather than the old

myForm.Show vbModal

you use

myForm.ShowDialog();

or

myForm.ShowDialog(myFormOwner);

This halts execution at the ShowDialog line just like the old vbModal used to.
