问题描述

void img_Hold(object sender, System.Windows.Input.GestureEventArgs e)
        {
            BuildMenu();

            //var img = (Image)sender;

            //WriteableBitmap wb1 = new WriteableBitmap((BitmapSource)img.Source);

            //CompareImg(wb1, datacoll);
        }

        private void BuildMenu()
        {
            ContextMenu mainmenu = new ContextMenu();
            MenuItem delmenu = new MenuItem() { Header = "Delete", Tag = "Delete" };
            delmenu.Click += new RoutedEventHandler(delmenu_Click);
            mainmenu.Items.Add(delmenu);
            ContextMenuService.SetContextMenu(this.Photo_Pan, mainmenu);
        }

        void delmenu_Click(object sender, RoutedEventArgs e)
        {
            
        }

大家好，以上是我的代码的摘要，我希望能够从delmenu_Click事件访问img_hold事件的发件人对象.任何想法我会怎么做..谢谢

推荐答案

这几乎不需要解释！

This hardly needs an explanation!

void img_Hold(object sender, System.Windows.Input.GestureEventArgs e)
        {
            SenderObject = sender;
            BuildMenu();
 
            //var img = (Image)sender;

            //WriteableBitmap wb1 = new WriteableBitmap((BitmapSource)img.Source);

            //CompareImg(wb1, datacoll);
        }
 
        private object SenderObject;
 
        void delmenu_Click(object sender, RoutedEventArgs e)
        {
            if(SenderObject != null)
            {
            }
        }
