    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        press(20);
        if (Console.CapsLock)
        {
            TextBox1.Text = "C灯开启";
        }
        else
        {
            TextBox1.Text = "C灯关闭";
        }

    }
    protected void Button3_Click(object sender, EventArgs e)
    {
        press(145);
        if (ScrollLock == false)
        {
            TextBox3.Text = "S灯开启";
        }
        else
        {
            TextBox3.Text = "S灯关闭";
        }
    }

    protected void Button2_Click(object sender, EventArgs e)
    {
        press(144);
        if (Console.NumberLock)
        {
            TextBox2.Text = "N灯开启";
        }
        else
        {
            TextBox2.Text = "N灯关闭";
        }
    }

}

在vs中使用iis experss调试时button是正常执行的，但是换成本地iis或者发布到iis上就失效了，页面可以打开但是并不执行。

解决方案

端口号对么？要不关闭防火墙试试看

解决方案二：

权限不一样，iis experss以administrator身份运行的，iis网站一般以匿名用户（guest）身份运行，你去配置iis网站以管理员身份运行，或者user32.dll加上guest组用户读取运行权限
