问题描述

如何以拖放方式将文件加载到表单?

How can I load files to a form in drag and drop way?

哪个活动会上映? (dragdrop,我是对的:) :)

Which event will appearence? ( dragdrop, am i right? :) )

我应该使用哪个组件? (试图使用面板,但没有发生任何事情:()

Which component should I use? (trying to use panel, but nothing happens:( )

在拖动它以形成后,如何确定文件和其他属性的名称?

And how to determine name of file and others properties after drag'n'dropping it to form?

谢谢!

代码

   private void panel1_DragEnter(object sender, DragEventsArgs e){
        if (e.Data.GetDataPresent(DataFormats.Text)){
              e.Effect = DragDropEffects.Move;
              MessageBox.Show(e.Data.GetData(DataFormats.Text).toString());
        }
        if (e.Data.GetDataPresent(DataFormats.FileDrop)){

        }
   }

okey,这项工作。

okey, this work.

但是文件怎么样?我如何获得文件的全名,它的.extension?

but how about files? how can I get fullname of file and it's .extension?

而这只是 dragEnter action
如果我尝试在dragdrop操作中做类似的事情,它不起作用:\
(以释放模式运行)

and this only dragEnter action. If i trying make something similar in dragdrop action, it does't work:\ ( running in Release-mode )

推荐答案

此代码将l oop遍历并打印拖到窗口中的所有文件的全名(包括扩展名):

This code will loop through and print the full names (including extensions) of all the files dragged into your window:

if (e.Data.GetDataPresent(DataFormats.FileDrop))
{
      string[] files = (string[])e.Data.GetData(DataFormats.FileDrop);
      foreach (string filePath in files) 
      {
          Console.WriteLine(filePath);
      }
}
