WPF后台动态生成右键菜单

 #region 循环生成右键菜单
        private ContextMenu ContextMenus(Dictionary<string, RoutedEventHandler> list)
        {
            ContextMenu cm = new ContextMenu();
            Style style = (Style)this.FindResource("ContextMenu"); //定义前台显示模板
            cm.Style = style;
                foreach (var dc in list)
                {
                    MenuItem menu = new MenuItem();
                    menu.Style = (Style)this.FindResource("JjxyMenuItem");
                    menu.Header = dc.Key;
                    menu.Click += dc.Value;
                    cm.Items.Add(menu);
                }

            return cm;
        }
        #endregion

需要右键菜单的地方使用：

Dictionary<string, RoutedEventHandler> dist = new Dictionary<string, RoutedEventHandler>();
            //添加右键菜单项，包括名称和事件
            dist.Add("添加", add_Click);
            dist.Add("修改", edit_Click);
            dist.Add("删除", del_Click);
            dist.Add("导出", putout_Click);
            dgrid.ContextMenu = ContextMenus(dist);

添加即可，dgrid为DataGrid实例对象，使用字典，string为菜单名，RoutedEventHandler为菜单事件。
