解决方案

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（）

I'm trying to drag and drop one picture box into another picture box. please help me! thanks Best Regards

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()
