C# 具有相同事件的文本框的继承

我需要创建10个或更多具有相同事件和逻辑的文本框， 不是复制粘贴，而是选择创建一次，然后从中继承？ 例如，name1将从name继承

<TextBox x:Name="Name" AcceptsReturn="True" AllowDrop="True"
         PreviewDragEnter="DropText_PreviewDragEnter"
         PreviewDrop="DropText_PreviewDrop"
         SelectionChanged="listbox_SelectionChanged"
         HorizontalAlignment="Left" Height="25" TextWrapping="Wrap"
         VerticalAlignment="Top" Width="150" Grid.Column="4" Margin="0,50,0,0" 
         Grid.Row="2" />

<TextBox x:Name="name1" AcceptsReturn="True" AllowDrop="True"
         PreviewDragEnter="DropText_PreviewDragEnter"
         PreviewDrop="DropText_PreviewDrop"
         SelectionChanged="listbox_SelectionChanged"
         HorizontalAlignment="Left" Height="25" TextWrapping="Wrap"
         VerticalAlignment="Top" Width="150" Grid.Column="4" Margin="0,50,0,0"
         Grid.Row="2" />

正如HighCore在评论中提到的，

ItemsControl

可能对您有所帮助

创建一个ItemsControl，并将itemstemplate设置为包含文本框。（创建ObjectDataProvider以返回所需的文本框数量）

然后，您可以使用Style来声明那个里的公共属性和事件，只需拥有引用该样式的TextBox的多个实例

<Grid>
   <Grid.Resources>
      <Style TargetType="TextBox">
          <Setter Property="AcceptsReturn" Value="True"/>
          <Setter Property="AllowDrop" Value="True"/>
          <Setter Property="HorizontalAlignment" Value="Left"/>
          <Setter Property="Height" Value="25"/>
          <Setter Property="Width" Value="150"/>
          <Setter Property="TextWrapping" Value="Wrap"/>
          <Setter Property="VerticalAlignment" Value="Top"/>
          <Setter Property="Margin" Value="0,50,0,0"/>
          <EventSetter Event="PreviewDragEnter"
                       Handler="DropText_PreviewDragEnter"/>
          <EventSetter Event="PreviewDrop"
                       Handler="DropText_PreviewDrop"/>
          <EventSetter Event="SelectionChanged"
                       Handler="listbox_SelectionChanged"/>
       </Style>
   </Grid.Resources>

   <TextBox x:Name="Name"/>
   <TextBox x:Name="Name1"/>
    ......
   <TextBox x:Name="Name15"/>
</Grid>

......

注意，我没有在样式上设置

x:Key

，因此默认情况下它将应用于网格中的所有文本框。如果您不希望设置

x:Key

并将其用于所有文本框。

您可以创建文本框的控件模板作为资源。将资源标记为x:Shared=False

<Grid.Resources>
   <ControlTemplate TargetType="TextBox" x:Key="TxtBoxTemplate" x:Shared="False">
<Grid.Resources>

在textbox的其他实例上使用此模板

    <TextBox x:Name="name1" Grid.Row="0" Template="{StaticResource TxtBoxTemplate}"/>
    <TextBox x:Name="name2" Grid.Row="1" Template="{StaticResource TxtBoxTemplate}"/>
    <TextBox x:Name="name3" Grid.Row="2" Template="{StaticResource TxtBoxTemplate}"/>

<Grid>

            <ControlTemplate TargetType="TextBox" x:Key="TxtBoxTemplate" x:Shared="False">

                AcceptsReturn="True"
                AllowDrop="True" 
                PreviewDragEnter="DropText_PreviewDragEnter"

#第一种方法：创建一个名为customTextbox.cs的类，并记录textbox的属性和事件

public class customTextbox:TextBox
{
   public customTextbox():base()
   {
       this.AcceptsReturn = true;
       this.AllowDrop = true;
       this.HorizontalAlignment = System.Windows.HorizontalAlignment.Left; 
       //set your remaining propreties
       this.PreviewDragEnter +=customTextbox_PreviewDragEnter;
       this.PreviewDragLeave +=customTextbox_PreviewDragLeave;
       this.SelectionChanged += customTextbox_SelectionChanged;         
   }

   void customTextbox_SelectionChanged(object sender, System.Windows.RoutedEventArgs e)
   {
       //code here
   }
   private void customTextbox_PreviewDragLeave(object sender, System.Windows.DragEventArgs e)
   {
       //code here
   }

   private void customTextbox_PreviewDragEnter(object sender, System.Windows.DragEventArgs e)
   {
      //code here 
   }     
}

在xaml中

<Window x:Class="WpfApplication3.MainWindow"
