单击按钮[复制]时获取鼠标坐标

如果需要,可以使用自定义按钮或创建行为。还可以将属性添加到viewmodel中 public Point MousePosition{get;set;}

<local:CustomButton  Command="{Binding Model.ZoomOnImage}" MousePosition="{Binding MousePosition}">
    <Image Source="{Binding Model.ImageSource}" Stretch="Uniform" />
</local:CustomButton>

public class CustomButton : Button
{

    public Point MousePosition
    {
        get { return (Point)GetValue(MousePositionProperty); }
        set { SetValue(MousePositionProperty, value); }
    }
    // Using a DependencyProperty as the backing store for MousePosition.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty MousePositionProperty = DependencyProperty.Register("MousePosition", typeof(Point), typeof(CustomButton), new FrameworkPropertyMetadata(new Point(), FrameworkPropertyMetadataOptions.BindsTwoWayByDefault));

    protected override void OnClick()
    {
        base.OnClick();
        MousePosition = Mouse.GetPosition(this);
    }
}
