问题描述

in Form1

public PictureBox pic
       {
           get
           {
               return pictureBox1;
           }
       }

Form2中的
，

in Form2,

private void button5_Click(object sender, EventArgs e)
      {
          getpic();
      }


      private void getpic()
      {
          Form1 frm = new Form1();
          frm.pic.Visible = true;
      }

我尝试过：



我尝试过上面的代码。我没有得到任何错误，但它没有给出所需的输出。同样基于测试结果我需要从form2加载图像（如果传递 - tickmark.jpg，如果失败 - Xmark.jpg）。请告诉我如何实现结果。

What I have tried:

I have tried with the above code. I am not getting any error but also it doesn't gives the desired output. Also based upon the test result i need to load the image from form2 (if pass - tickmark.jpg,if fail - Xmark.jpg). Please let me know how to achieve the result.
