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:00.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
