If you're fine with using TextBlock instead of Label(you should be!), then you can do it like this:
如果您可以使用TextBlock 而不是 Label（您应该这样做！），那么您可以这样做：
<TextBlock>
<Run Text="First Line"/>
<LineBreak/>
<Run Text="Second Line"/>
</TextBlock>
You can do this from code behind as well (not sure why you would want to though):
您也可以从后面的代码中执行此操作（但不确定为什么要这样做）：
tb.Inlines.Add(new Run("First Line"));
tb.Inlines.Add(new LineBreak());
tb.Inlines.Add(new Run("Second Line"));

I don't think that Environment.NewLineis not working in your case. Check the height of your label in XAML. When you add a Line Break then it increases the content in label and if height is not enough then you cant see that. I think you are facing this problem other wise i don't see any problem with Environment.NewLine:) Try adding height and tell me
我不认为这Environment.NewLine在你的情况下不起作用。检查 XAML 中标签的高度。当您添加换行符时，它会增加标签中的内容，如果高度不够，则您看不到。我认为您正面临这个问题，否则我认为没有任何问题Environment.NewLine:) 尝试添加高度并告诉我

Either set your max width and let the layout mechanism work out where to put your carriage return or put some \n in there
要么设置你的最大宽度，让布局机制计算在哪里放回车或放一些 \n 在那里
TextBlock tb = new TextBlock();
tb.Text = "This is a line with a carriage return";
tb.MaxWidth = 100;
tb.TextWrapping = TextWrapping.Wrap;
pan.Children.Add(tb);
in the code above, pan is just a stack panel control, you'll be adding to whatever control houses your label of course
在上面的代码中， pan 只是一个堆栈面板控件，当然，您将添加到包含您的标签的任何控件中
