C＃Drag Drop to desktop，并获取目录

Question

private void Form1_MouseDown(object sender, MouseEventArgs e)
{
    string[] files = new string[] { @"C:\directory\of\file\to\copy.txt" };
    this.DoDragDrop(new DataObject(DataFormats.FileDrop,files), DragDropEffects.Copy);
} 

This is the code that i used.

Well, it works well, but want to get the directory of the copied file. How can I do this?

Answer 1

使用System.IO的静态Path类，可以提取目录的路径

Path.GetDirectoryName(@"C:\Users\JNK\Desktop\2136D.png");

Answer 2

All you got is the return value of DoDragDrop() to see if the drop actually happened. What the receiving app did with the file is something you cannot find out. Could be anything, including not copying the file at all. A random example is only opening the file in a text editor, the behavior of VS and Notepad.

Note how the example you gave only drags from the desktop, not to the desktop. Use FileBrowserDialog if you need to know where the user wants to copy a file.
