winform(C#)拖拽实现获得文件路径

private void Form1_DragDrop(object sender, DragEventArgs e)
{
string path = ((System.Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString();
MessageBox.Show(path);

}

private void Form1_DragEnter(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent(DataFormats.FileDrop))
e.Effect = DragDropEffects.Link;
else e.Effect = DragDropEffects.None;

}
