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(我虽然相同);

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？

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.为什么我无法添加内联文本Textblock并要求我使用Run？

你需要:

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