提问by Galled
?How can I add a breakline to a text inside a tooltip in XAML?
?如何在 XAML 中的工具提示内向文本添加特征线？
I try with this:
我试试这个：
<Label Name="label4" UseLayoutRounding="False" Focusable="False" AllowDrop="False" Foreground="Black" Margin="6,44,132.027,76" ToolTipService.ShowDuration="12000">
<Label.ToolTip>
<ToolTip>
<TextBlock>Lorem ipsum dolor sit amet, consectetur adipiscing elit. </TextBlock>
<TextBlock>Suspendisse eget urna eget elit ullamcorper tincidunt. Sed nec arcu sed ante sodales </TextBlock>
<TextBlock>Pellentesque elit libero, semper ac tincidunt vitae, euismod at ligula.</TextBlock>
</ToolTip>
</Label.ToolTip>
<Label.Content>
<TextBlock TextAlignment="Right" TextWrapping="Wrap" Height="19" Width="108" >Lorem Ipsum</TextBlock>
</Label.Content>
</Label>

Another approach that I find useful is to embed 
in the tooltip. The Tooltip will then have a Linebreak at this point. For example
我认为有用的另一种方法是嵌入
到工具提示中。此时工具提示将有一个换行符。例如
ToolTip="Host name or IP address of the server. Click the 
Find Server button to help obtain the correct entry."
This allows the xaml code to be more concise, but perhaps less readable. More details at Newline in string attribute.

Wrap your items in a StackPanel, which will stack them one on top of the other
将您的项目包裹在 StackPanel 中，这会将它们堆叠在另一个之上
What you have now won't compile because ToolTips can only have 1 child object, and you are trying to add 3
您现在拥有的将无法编译，因为 ToolTips 只能有 1 个子对象，而您正在尝试添加 3
<Label Name="label4" UseLayoutRounding="False" Focusable="False" AllowDrop="False" Foreground="Black" Margin="6,44,132.027,76" ToolTipService.ShowDuration="12000">
<Label.ToolTip>
<StackPanel>
<TextBlock>Lorem ipsum dolor sit amet, consectetur adipiscing elit. </TextBlock>
<TextBlock>Suspendisse eget urna eget elit ullamcorper tincidunt. Sed nec arcu sed ante sodales </TextBlock>
<TextBlock>Pellentesque elit libero, semper ac tincidunt vitae, euismod at ligula.</TextBlock>
</StackPanel>
</Label.ToolTip>
<Label.Content>
<TextBlock TextAlignment="Right" TextWrapping="Wrap" Height="19" Width="108" >Lorem Ipsum</TextBlock>
</Label.Content>

Above answers are only for xaml code. If you want to add new line in CS code , use "Environment.Newline"
以上答案仅适用于 xaml 代码。如果要在 CS 代码中添加新行，请使用“Environment.Newline”
label1.ToolTip="Line1" + Environment.NewLine + "Line2";

You can do this :
你可以这样做 ：
<Label>
<Label.ToolTip>
<TextBlock>
Line1
<LineBreak/>
Line2
</TextBlock>
</Label.ToolTip>
</Label>

Here's a variation of the line feed approach:
这是换行方法的一种变体：
<Label.ToolTip>
<TextBlock>
<Run Text=”Line1”/>
<LineBreak/>
<Run Text=”Line2”/>
</TextBlock>
</Label.ToolTip>
The advantage of this is that each line can have its own style.
这样做的好处是每条线都可以有自己的风格。

Even though you are looking for a XAML solution - here another C# solution:
即使您正在寻找 XAML 解决方案 - 这是另一个 C# 解决方案：
If you plan by any chance to outsource your strings including tooltips to a resource file (.resx) - for example for multi language support - you can literally do line breaks in your values in this resource file e.g. with Shift+Enterand they will also occur in the view.
如果您计划有机会将您的字符串（包括工具提示）外包给资源文件 (.resx) - 例如用于多语言支持 - 您可以在此资源文件中的值中进行换行，例如使用Shift+ Enter，它们也会出现在风景。

From the code behindwith a bindingfor example.
从后面的代码与结合对的例子。
You can use this class:
你可以使用这个类：
Environment.NewLine
like this:
像这样：
labelName.Tooltip = $"line1 {Environment.NewLine} line2 {Environment.NewLine} line3";
