我想点击按钮就显示picture1 再次单击就隐藏 下面的实现不了  到底代码怎么写
private bool bool_a_b = false;
private bool bool_a_b_c = false;
  private void button1_Click(object sender, EventArgs e)
        {
            if (bool_a_b == false && bool_a_b_c == false)
            {
                pictureBox1.Visible = true;
            }
            else

                if (bool_a_b == false && bool_a_b_c == true)
                {
                    pictureBox1.Visible = false ;
                }
                else
                    if (bool_a_b == true && bool_a_b_c == true)
                    {
                        pictureBox1.Visible = false;
                    }
                else

                        if (bool_a_b == true && bool_a_b_c == false)
                        {
                            pictureBox1.Visible = true;
                        }
              
        }

。。我很无语
 private void button1_Click(object sender, EventArgs e)
        {
            if (pictureBox1.Visible == true)
            {
                pictureBox1.Visible = false;
            }
            else
            {
                pictureBox1.Visible = true;
            }
        }

private void button1_Click(object sender, EventArgs e)
        {
            pictureBox1.Visible = !pictureBox1.Visible
        }

嘿嘿，你是故意的唆~你的写法确实比我好，代码简练些，可是耐读性恐怕没我的好。

老实说，我看到全是英文就不想读下去了。


取非 相信 没有高级语言 没有这个 关键字的了。。

啊
可是实现不了那功能啊
怎么回事？

用你的代码也没实现
？？？？？
怎么回事？

对不起啊
是我弄错了
你们的都可以
