但是，如果我只是像这样向我的按钮添加内容属性
<AAD:Warning Grid.Row="11" Grid.ColumnSpan="3" Content="Bla Bla Bla"/>
元素中的XAML是UserControl的内容。默认情况下，它包含一个按钮。您正在将按钮替换为文本，因此可以看到文本而不是按钮。你不会失去按钮的风格。你把整个按钮都弄丢了
<AAD:Warning Grid.Row="11" Grid.ColumnSpan="3" Content="Bla Bla Bla"/>
您没有做任何可能将usercontrol的内容放在按钮内的事情。如果要这样做，您需要设置UserControl的模板：该模板确定内容的显示方式（您自己的按钮模板正好演示了这一点）。像这样：
<UserControl
x:Class="AADControls.Buttons.Warning"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:local="clr-namespace:AADControls.Buttons"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300"
Content="AAD Button"

<UserControl.Resources>

<LinearGradientBrush x:Key="aad-warning-border-brush" StartPoint="0.5,0" EndPoint="0.5,1">
<GradientStop Offset="0" Color="#FFF0F200"/>
<GradientStop Offset="1" Color="#FFFF8800"/>
</LinearGradientBrush>
</UserControl.Resources>
<!-- This template contains the XAML you had for the Content. -->
<UserControl.Template>
<ControlTemplate TargetType="UserControl">
<Button

Content="{TemplateBinding Content}"

这将是usercontrol的默认内容，除非您给它一些不同的内容，否则它将显示在按钮中。例如，在这里，您将为其提供内容“blablabla”，该内容将显示在按钮中
<AAD:Warning Grid.Row="11" Grid.ColumnSpan="3" Content="Bla Bla Bla"/>
非常感谢我的朋友给我完整的答案和建议descriptions@AminAmiriDarban很乐意帮忙。
<AAD:Warning Grid.Row="11" Grid.ColumnSpan="3" Content="Bla Bla Bla"/>
