如何将 WPF 富文本框转换为字符串 [英] How to get a WPF rich textbox into a string

问题描述

我看到了如何在 WPF 富文本框"https://msdn.microsoft.com/en-us/library/system.windows.controls.richtextbox.aspx" rel="noreferrer">RichTextBox 类.

I saw how to set a WPF rich text box in RichTextBox Class.

但我喜欢像以前一样将其文本保存到数据库中，在 Windows 窗体.

Yet I like to save its text to the database like I used to, in Windows Forms.

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

我该怎么做?

推荐答案

在 MSDN 底部 RichTextBox 参考有一个链接到 如何从 RichTextBox 中提取文本内容

At the bottom of the MSDN RichTextBox reference there's a link to How to Extract the Text Content from a RichTextBox

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;
}
