Set RTF text into WPF RichTextBox control
提问by Andrija
I have this RTF text:
我有这个 RTF 文本：
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Arial;}}
{\colortbl ;\red0\green0\blue0;\red255\green0\blue0;}
\viewkind4\uc1\pard\qc\cf1\fs16 test \b bold \cf2\b0\i italic\cf0\i0\fs17
\par }
How to set this text into WPF RichTextBox?
如何将此文本设置为WPF RichTextBox？
Solution:
解决方案：
public void SetRTFText(string text)
{
MemoryStream stream = new MemoryStream(ASCIIEncoding.Default.GetBytes(text));
this.mainRTB.Selection.Load(stream, DataFormats.Rtf);
}

Do you really have to start with a string?
你真的必须从一个字符串开始吗？
One method to load RTF is this:
加载 RTF 的一种方法是：
rtfBox.Selection.Load(myStream, DataFormats.Rtf);
You probably should call SelectAll() before that if you want to replace existing text.
如果您想替换现有文本，您可能应该在此之前调用 SelectAll()。
So, worst case, you'll have to write your string to a MemoryStream and then feed that stream to the Load() method. Don't forget to Position=0 in between.
因此，最坏的情况是，您必须将字符串写入 MemoryStream，然后将该流提供给 Load() 方法。不要忘记在两者之间设置 Position=0。
But I'm waiting to see somebody to come up with something more elegant.
但我在等着看有人想出更优雅的东西。

Edit: This answer assumes WinForms instead of WPF.
编辑：此答案假定 WinForms 而不是 WPF。
Simply use RichTextBox.Rtf:
只需使用 RichTextBox.Rtf：
string rtf = @"{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Arial;}} {\colortbl ;\red0\green0\blue0;\red255\green0\blue0;} \viewkind4\uc1\pard\qc\cf1\fs16 test \b bold \cf2\b0\i italic\cf0\i0\fs17 \par } ";
richTextBox1.Rtf = rtf;

I wrote a really slick solution by extending the RichTextBox class to allow Binding to an actual rich text file.
我通过扩展 RichTextBox 类来允许绑定到实际的富文本文件，从而编写了一个非常巧妙的解决方案。

Loading a RichTextBox from an RTF file using binding or a RichTextFile control
回答by P.Brian.Mackey
Create an Extension method
创建扩展方法
public static void SetRtf(this RichTextBox rtb, string document)
{
var documentBytes = Encoding.UTF8.GetBytes(document);
using (var reader = new MemoryStream(documentBytes))
{
reader.Position = 0;
rtb.SelectAll();
rtb.Selection.Load(reader, DataFormats.Rtf);
}
}
Then you can do WinForm-esque style
然后你可以做WinForm-esque风格
richTextBox1.SetRtf(rtf);
richTextBox1.SetRtf(rtf);

It's working fine
