如何将 BlockUIContainer 中 RichTextBox 的内容保存为 RTF 文件? [英] How to save content of RichTextBox in BlockUIContainer, to RTF file?

问题描述

我使用 BlockUIContainer 制作了两个richtexbox，一个小的richtexbox 嵌套在一个大的richtextbox 中，请参阅下面的XAML 文件.

I made two richtexbox, one small richtexbox nested in a big richtextbox by using BlockUIContainer, see XAML file below.

    <RichTextBox IsDocumentEnabled="True"  x:Name="first" HorizontalAlignment="Left" Height="174" Margin="120,136,0,0" VerticalAlignment="Top" Width="254" TextChanged="first_TextChanged" MouseDoubleClick="first_MouseDoubleClick">
        <FlowDocument>
            <Paragraph>
                <Run Text="RichTextBox"/>
            </Paragraph>
            <BlockUIContainer>
                <RichTextBox IsReadOnly="True" x:Name="second"  MouseDoubleClick="second_MouseDoubleClick" Width="239" TextChanged="second_TextChanged">
                    <FlowDocument>
                        <Paragraph>
                            <Run Text="RichTextBox1"/>
                            <Run Language="en" Text="hh"/>
                        </Paragraph>
                    </FlowDocument>
                </RichTextBox>
            </BlockUIContainer>
        </FlowDocument>
    </RichTextBox>

我想将两个 Richtexbox 的内容保存在一个 RTF 文件中.通常我们可以使用 TextRange(richTextBox.Document.ContentStart, richTextBox.Document.ContentEnd)，因为现在我们已经嵌套了 Richtexbox，所以我认为 TextRange 可能无法正常工作.也许我会在richtextbox中添加一些图像，所以我想尝试二进制流，见下文.第一个"是大富文本框的名称.THE PATH 是 RTF 文件的路径.

I want contents of both richtexbox saved in a RTF file. Normally we can use TextRange(richTextBox.Document.ContentStart, richTextBox.Document.ContentEnd), since now we have nested richtexbox, so i think TextRange is probablly not working. And maybe i will add some images in the richtextbox, so I want to try binary stream, see below. "first" is the name of big richtextbox. THE PATH is the path for RTF file.

FlowDocument document = first.Document;
System.IO.Stream ms = new System.IO.MemoryStream();
System.Windows.Markup.XamlWriter.Save(document, ms);
byte[] data = new byte[ms.Length];
ms.Position = 0;
ms.Read(data, 0, data.Length);
ms.Close();
File.WriteAllBytes(THE PATH, data);

但是在保存的 RTF 文件中，当我打开它时，它显示如下，

But in the saved RTF file, when i open it, it shows like this,

<FlowDocument PagePadding="5,0,5,0" AllowDrop="True"    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"> <Paragraph>RichTextBox</Paragraph><Paragraph><Run xml:lang="en">test test test!!!</Run></Paragraph><BlockUIContainer><RichTextBox IsReadOnly="True" Name="second" Width="239"><FlowDocument PagePadding="5,0,5,0" AllowDrop="True"><Paragraph>RichTextBox1<Run xml:space="preserve"> </Run><Run xml:lang="en">hhthis is a small richtextbox</Run></Paragraph><Paragraph><Run xml:lang="en" xml:space="preserve" /></Paragraph></FlowDocument></RichTextBox></BlockUIContainer></FlowDocument>

我不想在保存的文件中看到 XAML 纯文本，我希望它像普通的 Word 文档一样显示，见下文.大概还可以看到小的richtextbox的边框线(这条边框线下面没有显示)

I don´t want to see XAML plain text in the saved file, I want it to show like a normal word document, see below. and probably also see the border line of the small richtextbox (this border line doesnot show below)

RichTextBox
test test test!!!
RichTextBox1 hhthis is a small richtextbox

我该怎么办?或者 BlockUIContainer 嵌套的 Richtextbox 不能这样显示?

What should I do? or nested richtextbox by BlockUIContainer is not possible to show like this?

推荐答案

您可以通过保存并指定格式来实现.我省略了不必要的代码，只是将 memorystream 替换为您当前拥有的代码.

You can do it by saving it and specifying the format. I omit the unnecessary code, but just replace memorystream with what you currently have.

richTextBox.SelectAll();
richTextBox.Selection.Save(new MemoryStream(), DataFormats.Rtf);

XamlWriter 将其保存为 XAML 格式

XamlWriter will save it as a XAML format
