C#.NET 支持文件拖放

 

新建文本框txtSrcFname，设计其AllowDrop为true，处理DragEnter、DragDrop 事件。

 1 private void txtSrcFname_DragEnter(object sender, DragEventArgs e)
 2 {
 3     if (e.Data.GetDataPresent(DataFormats.FileDrop))
 4         e.Effect = DragDropEffects.All;
 5     else
 6         e.Effect = DragDropEffects.None;
 7 }
 8 
 9 private void txtSrcFname_DragDrop(object sender, DragEventArgs e)
10 {
11     string[] s = (string[])e.Data.GetData(DataFormats.FileDrop, false);
12     txtSrcFname.Text = "";
13     if (s.Length > 0)
14         txtSrcFname.Text = s[0];
15 }
