以下是Help的範例,但是只針對某一個Item而已,小弟需要複選的, 不知該如何去做... 請幫幫我吧..謝謝.. private void listBox1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) { // Determines which item was selected. ListBox lb =( (ListBox)sender); Point pt = new Point(e.X,e.Y); int index = lb.IndexFromPoint(pt); // Starts a drag-and-drop operation with that item. if(index>=0) { lb.DoDragDrop(lb.Items[index].ToString(), DragDropEffects.Link); } } private void richTextBox1_DragEnter(object sender, DragEventArgs e) { // If the data is text, copy the data to the RichTextBox control. if(e.Data.GetDataPresent("Text")) e.Effect = DragDropEffects.Copy; } private void richTextBox1_DragDrop(object sender, DragEventArgs e) { // Loads the file into the control. richTextBox1.LoadFile((String)e.Data.GetData("Text"), System.Windows.Forms.RichTextBoxStreamType.RichText); } 他是再滑鼠點下去選取某一個Item,但是我是需要多個Item複選,所以在 e.Data.GetData 中,他用 e.Data.GetData("Text") 是取一個文字的值, 那我要取 SelectItems 的 Object, 該怎麼做呢 ??? 請幫幫我吧..謝謝..
