How do I show a Save As dialog in WPF?

Question

I have a requirement in WPF/C# to click on a button, gather some data and then put it in a text file that the user can download to their machine. I can get the first half of this, but how do you prompt a user with a "Save As" dialog box? The file itself will be a simple text file.

Both answers thus far link to the Silverlight SaveFileDialogclass; the WPF variant is quite a bit different and differing namespace.

Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog(); dlg.FileName = "Document"; // Default file name dlg.DefaultExt = ".text"; // Default file extension dlg.Filter = "Text documents (.txt)|*.txt"; // Filter files by extension  // Show save file dialog box Nullable<bool> result = dlg.ShowDialog();  // Process save file dialog box results if (result == true) {     // Save document     string filename = dlg.FileName; }
