//参考如下代码
private void textBox1_DragDrop(object sender, DragEventArgs e)
{
Array vFiles = (System.Array)e.Data.GetData(DataFormats.FileDrop);
foreach (object vFile in vFiles)
{
((TextBox)sender).AppendText(vFile.ToString() + "\r\n ");
}
}

private void ListDragTarget_DragDrop(object sender, System.Windows.Forms.DragEventArgs e)
{
// Ensure that the list item index is contained in the data.
if (e.Data.GetDataPresent(typeof(System.String))) {

Object item = (object)e.Data.GetData(typeof(System.String));

// Perform drag-and-drop, depending upon the effect.
if (e.Effect == DragDropEffects.Copy ||
e.Effect == DragDropEffects.Move) {

// Insert the item.
if (indexOfItemUnderMouseToDrop != ListBox.NoMatches)
ListDragTarget.Items.Insert(indexOfItemUnderMouseToDrop, item);
else
ListDragTarget.Items.Add(item);

}
}
// Reset the label text.
DropLocationLabel.Text = "None";
}
