# How to: Open a Message Box
|
|
This example shows how to open a message box.
|
|
|
|
## Example
|
|
A message box is a prefabricated modal dialog box for displaying information to users. A message box is opened by calling the static <xref:System.Windows.MessageBox.Show%2A> method of the <xref:System.Windows.MessageBox> class. When <xref:System.Windows.MessageBox.Show%2A> is called, the message is passed using a string parameter. Several overloads of <xref:System.Windows.MessageBox.Show%2A> allow you to configure how a message box will appear (see <xref:System.Windows.MessageBox>).
