我想知道如何拖放文件夹并获取其名称。我已经知道如何使用文件,但我不确定如何修改它以便能够拖动文件夹。这是删除文件时触发的事件代码:
private void checkedListBox_DragDrop(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent(DataFormats.FileDrop))
{
// NB: I'm only interested in the first file, even if there were
// multiple files dropped
string fileName = ((string[])e.Data.GetData(DataFormats.FileDrop))[0];
}
}
答案 0 :(得分:6)
您可以测试路径是否为文件夹,并在DragEnter
handler中,有条件地更改Effect
:
void Target_DragEnter(object sender, DragEventArgs e)
{
DragDropEffects effects = DragDropEffects.None;
if (e.Data.GetDataPresent(DataFormats.FileDrop))
{
var path = ((string[])e.Data.GetData(DataFormats.FileDrop))[0];
if (Directory.Exists(path))
effects = DragDropEffects.Copy;
}
e.Effect = effects;
}
