WPF Multiline TextBlock LineBreak问题

Question

我有以下代码

txtBlock1.Inlines.Add("This is first paragraph \n This is second paragraph");

然后TextBlock将显示：

This is first paragraph
This is second paragraph

但是，如果我有以下（我相同）;

txtBlock1.Inlines.Add("This is first paragraph");
txtBlock1.Inlines.Add("\n");
txtBlock1.Inlines.Add("This is second paragraph");

TextBlock显示：

This is first paragraph // but second paragraph missing

如果我将换行分开，则换行后的其余文本不会显示。为什么呢？

我必须使用run：

Run run1 = new Run();
run1.Text = "First Paragraph";
run1.Text += "\n";
run1.Text += "Second Paragraph";
txtBlock1.Inlines.Add(run1); 

然后它正确地产生结果。为什么我无法将内嵌文字添加到Textblock并要求我使用Run？

请参阅此答案：What the best way to get paragraphs in a WPF textblock? (newline chars?)

你需要：

txtBlock1.Inlines.Add("This is first paragraph");
txtBlock1.Inlines.Add(new LineBreak());
txtBlock1.Inlines.Add("This is second paragraph");
