更新:做个小把戏

    bool holdsImage = false;
    Control currentControl = null;
    private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
    {
        holdsImage = true;           
    }

    private void pictureBox2_MouseEnter(object sender, EventArgs e)
    {
        currentControl = pictureBox2;
    }

    private void pictureBox2_MouseLeave(object sender, EventArgs e)
    {
        currentControl = null;
    }

    private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
    {
        if (holdsImage && currentControl==pictureBox2)
        {
            pictureBox2.Image = pictureBox1.Image;
            pictureBox1.Image = null;
        }
        holdsImage = false;
        currentControl = null;
    }

问题是我无法在 PictureBox 中找到 AllowDrop 属性,否则 DoDragDrop()

Problem is that I am unable to find AllowDrop property in PictureBox else it will be easy to implement by DoDragDrop()
