Question

rt，
最好给个完整的例子。

Answer 1

label啊我拖label1到label2上，label2就显示label1的text值

Answer 2

哦 这个简单这个是互换LABEL的TEXT
设置Label.AllowDrop = true; 
 private void label2_DragEnter(object sender, DragEventArgs e)
        {
            if (m_Drop)
            {               
                e.Effect = DragDropEffects.All;
            }
        }        private void label2_DragDrop(object sender, DragEventArgs e)
        {
            Label _Label = (Label)sender;
            string _StarText = e.Data.GetData("Text").ToString();            
            m_Label.Text = _Label.Text;
            _Label.Text = _StarText;
            m_Drop = false;
        }        private bool m_Drop = false;
        private Label m_Label;
        private void label2_MouseDown(object sender, MouseEventArgs e)
        {
            m_Drop = true;
        }        private void label2_MouseMove(object sender, MouseEventArgs e)
        {
            if (m_Drop)
            {
                m_Label = (Label)sender;
                Point _MousePoint = this.PointToClient(Cursor.Position);
                Control _Control = this.GetChildAtPoint(_MousePoint);
                if (_Control is Label)
                {
                    _Control.DoDragDrop(m_Label.Text, DragDropEffects.All);
                }
            }
        }
