MessageBox

System. Windows .Forms (system. windows .forms.dll)

class

This class provides a simple means to display a modal pop-up box with a title, message, and icon, and obtain some basic Yes/No, OK/Cancel information from the user . It is essentially a wrapper around the Win32 MessageBox() method.

You can Show() a message, which returns the DialogResult indicating which button the end user clicked. When showing the message, you can specify the title and body text, the MessageBoxButtons to show (and which button is the MessageBoxDefaultButton ), the MessageBoxIcon , and some MessageBoxOptions that deal with right-to-left mode, multiple desktop alignment, and alignment.

Don't forget that popping up a message box is highly intrusive , forcibly interrupting a users workflow. You might consider ErrorProvider , or even a ToolTip , as a better way of notifying the user of problems.
