如何在Powershell中将rtf文件加载到WPF RichTextBox

Question

Anyone know hoe I can load an rtf file to a wpf RichTextBox?

In Windows.Forms I would do this

RichTextFile.Loadfile(c:\myfile.rtf) 

but I don't know how to achieve the same in WPF!

Thanks,

Ben

Not sure about PowerShell, but the RichTextBox has a Document property that you use can load a RTF file.
Here is sample, plus some good sites that helped me:

• Some tricks for working with WPF's RichTextBox
• WPF RichTextBox
• WPF RichTextBox: How To Load, Edit and Save Rich Text Format

Here is the XAML:

<StackPanel>
    <RichTextBox Height="200" x:Name="rtb"/>
    <Button Content="Load" Click="Button_Click" Width="50" />
</StackPanel>

Here is the button click event to load the RTF:

public partial class MainView : Window
{
  public MainView()
  {
     InitializeComponent();
  }

  private void Button_Click(object sender, RoutedEventArgs e)
  {
     TextRange textRange;
     System.IO.FileStream fileStream;

     if (System.IO.File.Exists("Document.rtf"))
     {
        textRange = new TextRange(rtb.Document.ContentStart, rtb.Document.ContentEnd);
        using (fileStream = new System.IO.FileStream("Document.rtf", System.IO.FileMode.OpenOrCreate))
        {
           textRange.Load(fileStream, System.Windows.DataFormats.Rtf);
        }
     }
  }
}
