C# UWP中两个rtf的合并

我有两个字符串（RTF），我必须以某种方式合并-在两个字符串之间插入新行-以显示在UWP中的RichEditBox中。我读过一个变通方法，其中通过使用两个RichTextBox控件来合并这两个控件，但在UWP中，这并不是一个真正的选项（我也不能在两个RichEditBox控件中显示两个RTF）。有没有其他方法，不使用第三方库？

在使用时，我们可以利用 和。以下是一个简单的示例：

var rtf1 = @"{\rtf1{\fonttbl{\f0 Verdana;}{\f1 Arial;}{\f2 Verdana;}{\f3 Calibri;}}{\colortbl;\red255\green255\blue255;\red255\green0\blue0;}\f0\cf2 This is red text marked by Verdana font.\par}";

// Sets rtf1 as the content of the document
editor.Document.SetText(Windows.UI.Text.TextSetOptions.FormatRtf, rtf1);

// Get a new text range for the active story of the document.
var range = editor.Document.GetRange(0, rtf1.Length);

// Collapses the text range into a degenerate point at the end of the range for inserting.
range.Collapse(false);

var rtf2 = @"{\rtf1{\fonttbl{\f0 Times New Roman;}}{\colortbl;\red255\green255\blue255;\red0\green0\blue255;}\f0\cf2 This is blue text marked by Times New Roman font.\par}";

// Inserts rtf2
range.SetText(Windows.UI.Text.TextSetOptions.FormatRtf, rtf2);

//var newrtf = string.Empty;
//editor.Document.GetText(Windows.UI.Text.TextGetOptions.FormatRtf, out newrtf);

//System.Diagnostics.Debug.WriteLine(newrtf);

这将把rtf2合并到rtf1的末尾，并自动创建一个新的有效RTF。您可以使用检索新的RTF。
