                PictureBox2.MouseClick += form_MouseClick;
    
                PictureBox3.MouseClick += form_MouseClick;

            }
    		
    	private void frmRightClick_Disposed(object sender, EventArgs e)
            {
                folderBrowser.ShowDialog();
                string filepath = folderBrowser.SelectedPath;
                Image im = PictureBox1.Image;
                var obj = new Random();
                SaveImage(im, filepath + "\\" + obj.Next() + ".png");
            }
    		
    		private void SaveImage(Image im, string destPath)
            {
                im.Save(destPath, System.Drawing.Imaging.ImageFormat.Png);
            }

我的尝试：



我尝试使用发件人

What I have tried:

I tried using the sender

private void frmRightClick_Disposed(object sender, EventArgs e)
            {
                folderBrowser.ShowDialog();
                string filepath = folderBrowser.SelectedPath;
                Image im = PictureBox1.Image;
                var obj = new Random();
                SaveImage(im, filepath + "\\" + obj.Next() + ".png");
            }

推荐答案

事件处理程序的 sender 参数是出于这个原因：

The sender parameter of the event handler is there for just that reason:

private void form_MouseClick(object sender, EventArgs e)
    {
    PictureBox pb = sender as PictureBox;
    if (pb != null)
        {
        folderBrowser.ShowDialog();
        string filepath = folderBrowser.SelectedPath;
        Image im = pb.Image;
        var obj = new Random();
        SaveImage(im, filepath + "\\" + obj.Next() + ".png");
        }
    }
