picturebox中添加图片

 private void Form1_Load(object sender, EventArgs e)
         {
             radioButton2.Checked = true;
         }
         private void radioButton_CheckedChanged(object sender, EventArgs e)
         {
             if (radioButton2.Checked == true)
             {
                 pictureBox1.ImageLocation = @"C:\111.jpg";
             }
             else
             {
                 pictureBox1.ImageLocation = @"C:\000.jpg";
             }

         }

插入图片最简单的代码pictureBox1.ImageLocation = @"C:\111.jpg";

不同情况插入不同图片
