WPF中ControlTemplate和DataTemplate的区别

Answer 1

下面代码很好的解释了它们之间的区别：

<Window x:Class="WPFTestMe.Window12"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window12" Height="300" Width="300">
<Window.Resources>
<DataTemplate x:Key="ButtonContentTemplate">
<StackPanel Orientation="Horizontal" Background="Red">
<Grid Height="8" Width="8" >
<Path HorizontalAlignment="Stretch"
Margin="0,0,1.8,1.8"
VerticalAlignment="Stretch" Stretch="Fill" Stroke="#FF000000"
Data="M0.5,5.7 L0.5,0.5 L5.7,0.5"/>
<Path HorizontalAlignment="Stretch"
Margin="2,3,0,0"
VerticalAlignment="Stretch" Stretch="Fill" Stroke="#FFFFFFFF"
Data="M3.2,7.5 L7.5,7.5 L7.5,3.5"/>
<Path HorizontalAlignment="Stretch"
Margin="1.2,1.4,0.7,0.7"
VerticalAlignment="Stretch" Fill="#FFFFFFFF" Stretch="Fill" Stroke="#FF000000"
Data="M2.5,2.5 L7.5,7.5"/>
<Path HorizontalAlignment="Stretch"
Margin="1.7,2.0,1,1"
VerticalAlignment="Stretch" Stretch="Fill" Stroke="#FF000000"
Data="M3,7.5 L7.5,7.5 L7.5,3.5"/>
<Path HorizontalAlignment="Stretch"
Margin="1,1,1,1"
VerticalAlignment="Stretch" Stretch="Fill" Stroke="#FFFFFFFF"
Data="M1.5,6.5 L1.5,1 L6.5,1.5"/>
</Grid>
<ContentPresenter Content="{Binding}"/>
</StackPanel>
</DataTemplate>
<ControlTemplate TargetType="Button" x:Key="ButtonControlTemplate">
<Grid>
<Ellipse Fill="{TemplateBinding Background}"/>
<ContentPresenter HorizontalAlignment="Center"
VerticalAlignment="Center"/>
</Grid>
</ControlTemplate>
</Window.Resources>
<StackPanel>
<Button ContentTemplate="{StaticResource ButtonContentTemplate}" Content="1"/>
<Button Template="{StaticResource ButtonControlTemplate}" ContentTemplate="{StaticResource ButtonContentTemplate}" Content="2"/>
<Button Template="{StaticResource ButtonControlTemplate}" ContentTemplate="{StaticResource ButtonContentTemplate}" Content="3"/>
</StackPanel>
</Window>
