在Winform中实现拖放的功能

首先程序要从管理员权限启动

 

 

然后把控件的AllowDrop属性设为True

 

 

然后添加2个事件

 

  private void listBox1_DragDrop(object sender, DragEventArgs e)

        {

            if (e.Data.GetDataPresent(DataFormats.FileDrop))

            {

                string[] MyFiles = (string[])(e.Data.GetData(DataFormats.FileDrop));

                foreach (string t in MyFiles)

                {

                    listBox1.Items.Add(t);

                }

            }

        }

 

        private void listBox1_DragEnter(object sender, DragEventArgs e)

        {

            if (e.Data.GetDataPresent(DataFormats.FileDrop))

            {

                e.Effect = DragDropEffects.All;

            }

        }
