Question

我的C＃WPF应用程序中有一个函数（Method）。我想从几个图像控件中使用此方法。

WPF代码

 <Image x:Name="cardMPOne" HorizontalAlignment="Center" MouseDown="moveCard"  Height="220" Margin="-300,20,0,0" VerticalAlignment="Top"  Width="100"/>

C SHARP

private void moveCard(object sender, MouseButtonEventArgs e)
    {

        ThicknessAnimation move = new ThicknessAnimation();
        move.From = new Thickness(sender.Margin.Left, sender.Margin.Top, 0, 0);
        move.To = new Thickness(250, 250, 0, 0);
        move.Duration = new Duration(TimeSpan.FromSeconds(0.25));
        sender.BeginAnimation(MarginProperty, move);

    }

我希望这种方法能够适用于每一个被击中并调用它的图像。

我也尝试了这个

    private void moveCard(Image sender, MouseButtonEventArgs e){

        ThicknessAnimation move = new ThicknessAnimation();
        move.From = new Thickness(sender.Margin.Left, sender.Margin.Top, 0, 0);
        move.To = new Thickness(250, 250, 0, 0);
        move.Duration = new Duration(TimeSpan.FromSeconds(0.25));
        sender.BeginAnimation(MarginProperty, move);

    }

正常情况下没有显示错误。但是跑的时候。没有显示过载错误。但是当我使用MouseDown =“moveCard（cardMPOne）”时，XAML视图显示错误。令人困惑该怎么做。任何人的帮助表示赞赏..在此先感谢..

你不能从xaml提供这样的参数。而是将处理程序更新为：

private void moveCard(object sender, MouseButtonEventArgs e)
    {

        Image image = sender as Image;
        if(image ! =null)
        {
          ThicknessAnimation move = new ThicknessAnimation();
          move.From = new Thickness(image.Margin.Left, image.Margin.Top, 0, 0);
          move.To = new Thickness(250, 250, 0, 0);
          move.Duration = new Duration(TimeSpan.FromSeconds(0.25));
          image .BeginAnimation(MarginProperty, move);

       }
     }

如何从XAMLl视图向Csharp Wpf Application中的方法传递值？
