WPF多行TextBlock的斷行發出

Question

我有以下代碼

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

隨後的TextBlock將顯示：

This is first paragraph 
This is second paragraph 

但是，如果我有以下的（我雖然是當量）;

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

的TextBlock顯示：

This is first paragraph // but second paragraph missing 

如果我單獨拿出來斷行，然後文本斷行後，其餘不顯示。爲什麼？

我必須使用運行：

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

然後它產生正確的結果。爲什麼我無法將內聯文字添加到Textblock並要求我使用Run？

看到這個答案：What the best way to get paragraphs in a WPF textblock? (newline chars?)

您需要：

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