这是一个用WINFORM中实现的用于拖放操作和文件复制小功能，现在共享出来！下面的代码没有打入注释，加入了一个ListBox，当文件拖放上来后，将内容显示在里面
private void lstFilePath_DragEnter(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent(DataFormats.FileDrop))
{
e.Effect = DragDropEffects.Link;
}
else
{
e.Effect = DragDropEffects.None;
}
}
private void lstFilePath_DragDrop(object sender, DragEventArgs e)
{
foreach (string strPath in (string[])e.Data.GetData(DataFormats.FileDrop))
{
lstFilePath.Items.Add(strPath);
}
}
将整个窗体代码都复制下来，是一个复制的小程序，将拖放到LISTBOX里的文件复制到文本框里指定的位置,里面用到了一个外部控件，可以使用普通的button替换之
