一鍵處理程序中的StackPanel多個按鈕

Question

我有下面的XAML：

<GroupBox x:Name="GroupBoxInworp" IsEnabled="True" Header="Inworp" HorizontalAlignment="Stretch" Margin="10,120,10,0" VerticalAlignment="Top" VerticalContentAlignment="Stretch"> 
     <StackPanel x:Name="StackPanelInworp" Button.Click="button_Click"> 
      <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0"> 
       <Button x:Name="btnTweeEuro" Margin="10" MinWidth="220" Content="2" Click="btnTweeEuro_Click"></Button> 
       <Button x:Name="btnEenEuro" Margin="10" MinWidth="220" Content="1" Click="btnEenEuro_Click"></Button> 
      </StackPanel> 
      <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0"> 
       <Button x:Name="btnVijftigEurocent" Margin="10" MinWidth="100" Content="50" Click="btnVijftigEurocent_Click"></Button> 
       <Button x:Name="btnTwintigEurocent" Margin="10" MinWidth="100" Content="20" Click="btnTwintigEurocent_Click"></Button> 
       <Button x:Name="btnTienEurocent" Margin="10" MinWidth="100" Content="10" Click="btnTienEurocent_Click"></Button> 
       <Button x:Name="btnVijfEurocent" Margin="10" MinWidth="100" Content="5" Click="btnVijfEurocent_Click"></Button> 
      </StackPanel> 
      <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="5"> 
       <Label Content="Huidige inworp:" MinWidth="160"></Label> 
       <Label x:Name="lblHuidigeInworp" Content="" MinWidth="300" HorizontalContentAlignment="Right"></Label> 
      </StackPanel> 
     </StackPanel> 
    </GroupBox> 

我有以下代碼：

private void GeldClick(decimal Inworp) 
    { 
     TotaalInworp += Inworp; 
     lblHuidigeInworp.Content = String.Format("€ {0}", TotaalInworp); 
    } 

    private void btnTweeEuro_Click(object sender, RoutedEventArgs e) 
    { 
     GeldClick(2.00M); 
    } 

    private void btnEenEuro_Click(object sender, RoutedEventArgs e) 
    { 
     GeldClick(1.00M); 
    } 

    private void btnVijftigEurocent_Click(object sender, RoutedEventArgs e) 
    { 
     GeldClick(0.50M); 
    } 

    private void btnTwintigEurocent_Click(object sender, RoutedEventArgs e) 
    { 
     GeldClick(0.20M); 
    } 

    private void btnTienEurocent_Click(object sender, RoutedEventArgs e) 
    { 
     GeldClick(0.10M); 
    } 

    private void btnVijfEurocent_Click(object sender, RoutedEventArgs e) 
    { 
     GeldClick(0.05M); 
    } 

我想創建一個用於或所有點擊事件一個處理程序開關。

處理程序會像

StackPanelInworp.AddHandler(Button.ClickEvent, new RoutedEventHandler(button_Click)); 

我也想創建一個類，其中我可以將事件處理程序與用於或交換機。有6個按鈕。

這是如何實現的？另外，它關係到小數，所以我認爲切換是不可能的？

我想出了這一點： 的XAML

<StackPanel x:Name="StackPanelInworp"> 
      <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0"> 
       <Button x:Name="btnTweeEuro" Margin="10" MinWidth="220" Content="2" Click="btnGeld_Click"></Button> 
       <Button x:Name="btnEenEuro" Margin="10" MinWidth="220" Content="1" Click="btnGeld_Click"></Button> 
      </StackPanel> 
      <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0"> 
       <Button x:Name="btnVijftigEurocent" Margin="10" MinWidth="100" Content="50" Click="btnGeld_Click"></Button> 
       <Button x:Name="btnTwintigEurocent" Margin="10" MinWidth="100" Content="20" Click="btnGeld_Click"></Button> 
       <Button x:Name="btnTienEurocent" Margin="10" MinWidth="100" Content="10" Click="btnGeld_Click"></Button> 
       <Button x:Name="btnVijfEurocent" Margin="10" MinWidth="100" Content="5" Click="btnGeld_Click"></Button> 
      </StackPanel> 
      <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="5"> 
       <Label Content="Huidige inworp:" MinWidth="160"></Label> 
       <Label x:Name="lblHuidigeInworp" Content="" MinWidth="300" HorizontalContentAlignment="Right"></Label> 
      </StackPanel> 
     </StackPanel> 

代碼：

//Methode voor uitvoeren van alle click events mbt Geld 
    private void GeldClick(decimal Inworp) 
    { 
     TotaalInworp += Inworp; 
     lblHuidigeInworp.Content = String.Format("€ {0}", TotaalInworp); 
    } 

    //Enkel click event voor alle knoppen mbt Drank 
    private void btnGeld_Click(object sender, EventArgs e) 
    { 
     Button btn = sender as Button; 
     switch (btn.Content.ToString()) 
     { 
      case "2": 
       GeldClick(2.00M); 
       break; 
      case "1": 
       GeldClick(1.00M); 
       break; 
      case "50": 
       GeldClick(0.50M); 
       break; 
      case "20": 
       GeldClick(0.20M); 
       break; 
      case "10": 
       GeldClick(0.10M); 
       break; 
      case "5": 
       GeldClick(0.05M); 
       break; 
     } 
    } 

任何人都知道的改進？想要與按鈕的stackpanelname一起工作，但不知道如何...
