您可以添加HTML ＆LT; BR /＆GT; 在你的字里行间。是这样的：

You may append HTML <br /> in between your lines. Something like:

MyLabel.Text = "SomeText asdfa asd fas df asdf" + "<br />" + "Some more text";

是的StringBuilder 您可以试试：

StringBuilder sb = new StringBuilder();
sb.AppendLine("Some text with line one");
sb.AppendLine("Some mpre text with line two");
MyLabel.Text = sb.ToString().Replace(Environment.NewLine, "<br />");
