Question

我是C＃的初学者。我试图使用以下xaml：

在我的可视化C＃WPF应用程序中为我的按钮设置一些属性

<Grid>
    <Button Panel.ZIndex="1" Content="Button" Height="37" HorizontalAlignment="Stretch"
            Margin="378,12,38,262" Name="button1" VerticalAlignment="Stretch" Width="87" >
        <Button.Resources>
            <Style x:Key="buttonStyle">
                <Setter Property="Button.Background" Value="Gray"/>
                <Setter Property="Button.Foreground" Value="White"/>
                <Setter Property="Button.FontFamily" Value="Comic Sans MS"/>
            </Style>
        </Button.Resources>
    </Button>

    <Image Margin="0,0,0,0" Name="image1">
        <Image.Source>
            <BitmapImage UriSource="images.jpg"></BitmapImage>
        </Image.Source>
    </Image>
</Grid>

但Button.Resource对按钮的样式没有影响。任何人都可以告诉我这个问题

Answer 1

替换

<Button Panel.ZIndex="1" Content="Button" Height="37" HorizontalAlignment="Stretch"
        Margin="378,12,38,262" Name="button1" VerticalAlignment="Stretch" Width

与

<Button Style="{DynamicResource buttonStyle}" Panel.ZIndex="1"
Content="Button" Margin ="169,84,34,0" Name="button1" Height="23"
VerticalAlignment="Top">

Answer 2

您创建了明确的Button样式，但不要在任何地方使用它。您可以直接针对按钮

设置这些值

<Button ... Background="Gray" Foreground="White" FontFamily="Comic Sans MS"/>

或者，如果您想要创建明确的Style，则需要在Button

上使用它

<Grid>
    <Grid.Resources>
       <Style x:Key="buttonStyle" TargetType="{x:Type Button}">
           <Setter Property="Background" Value="Gray"/>
           <Setter Property="Foreground" Value="White"/>
           <Setter Property="FontFamily" Value="Comic Sans MS"/>
       </Style>
    </Grid.Resources>
    <Button ... Style="{StaticResource buttonStyle}"/>
</Grid>

或者您可以创建隐式样式，它将自动应用于当前可视树中的子Button控件

<Grid>
    <Grid.Resources>
       <Style TargetType="{x:Type Button}">
           <Setter Property="Background" Value="Gray"/>
           <Setter Property="Foreground" Value="White"/>
           <Setter Property="FontFamily" Value="Comic Sans MS"/>
       </Style>
    </Grid.Resources>
    <Button .../>
</Grid>

或仅为Style

创建Button

<Button>
   <Button.Style>
      <Style TargetType="{x:Type Button}">
         <Setter Property="Background" Value="Gray"/>
         <Setter Property="Foreground" Value="White"/>
         <Setter Property="FontFamily" Value="Comic Sans MS"/>
      </Style>
   </Button.Style>
</Button>

Answer 3

  <Window.Resources>
        <Style x:Key="ButtonStyle1" 
               TargetType="{x:Type Button}">
            <Setter Property="Button.Background" Value="Gray"/>
            <Setter Property="Button.Foreground" Value="White"/>
            <Setter Property="Button.FontFamily" Value="Comic Sans MS"/>
        </Style>
    </Window.Resources>
    <Grid>
        <Button Panel.ZIndex="1" Content="Button" Height="37" HorizontalAlignment="Stretch"
            Margin="378,12,38,262" Name="button1" VerticalAlignment="Stretch" Style="{StaticResource ButtonStyle1}" Width="87" >
        </Button>
        <Image Margin="0,0,0,0" Name="image1">
        </Image>
    </Grid>

Answer 4

你可以这样写：

        <Button Panel.ZIndex="1" Content="Button" Height="37" HorizontalAlignment="Stretch" 
            Margin="378,12,38,262" x:Name="button1" 
            VerticalAlignment="Stretch" Width="87" 
            Background="Gray" Foreground="White" FontFamily="Comic Sans MS" />
