做一个技巧

 code> bool heldImage = false; 
控制currentControl = null;
private void pictureBox1_MouseDown(object sender,MouseEventArgs e)
{
heldImage = 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(heldImage&& currentControl == pictureBox2)
{
pictureBox2.Image = pictureBox1.Image;
pictureBox1.Image = null;
}
heldImage = false;
currentControl = null;
}

问题是我无法在PictureBox中找到AllowDrop属性,否则会轻松实现 DoDragDrop()

Upadated:Do a trick

    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;
    }

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