wpf - 如何将 WPF 富文本框转换为字符串

Question

我看到了如何设置 WPF RichTextBox Class 中的富文本框.

然而我喜欢像以前一样将它的文本保存到数据库中，在 Windows Forms .

string myData = richTextBox.Text;
dbSave(myData);

我该怎么做？

MSDN底部RichTextBox引用有指向 How to Extract the Text Content from a RichTextBox 的链接

它看起来像这样:

public string RichTextBoxExample()
{
    RichTextBox myRichTextBox = new RichTextBox();

    // Create a FlowDocument to contain content for the RichTextBox.
    FlowDocument myFlowDoc = new FlowDocument();

    // Add initial content to the RichTextBox.
    myRichTextBox.Document = myFlowDoc;

    // Let's pretend the RichTextBox gets content magically ... 

    TextRange textRange = new TextRange(
        // TextPointer to the start of content in the RichTextBox.
        myRichTextBox.Document.ContentStart, 
        // TextPointer to the end of content in the RichTextBox.
        myRichTextBox.Document.ContentEnd
    );

    // The Text property on a TextRange object returns a string
    // representing the plain text content of the TextRange.
    return textRange.Text;
}
