Question

如果用户的浏览器兼容性已启用，则需要向用户显示您的浏览器兼容性已打开的消息。

我在google上搜索了很多但是没有找到合适的答案。

我试过下面的代码但是HttpContext.Current.Request.UserAgent总是包含MSIE 7.0

string isOn = string.Empty;

if (HttpContext.Current.Request.UserAgent.IndexOf("MSIE 7.0") > -1)
{
 isOn  = "IE8 Compatibility View";`   

    }
    else
    {
    isOn  = "IE8";
    }

}

您可以尝试这样

if (Request.Browser.Type.ToUpper().Contains("IE"))
{
    if (Request.Browser.MajorVersion  < 7)
    { 
        //Show the message here
    }
    ...
}
else if (Request.Browser.Type.Contains("Firefox")) 
{
   //code to show message
}
else if (Request.Browser.Type.Contains("Chrome")) 
{
   //code to show message
}

另请检查 MSDN ，它有自己的方式来检测浏览器

查询浏览器属性，其中包含HttpBrowserCapabilities 宾语。此对象从浏览器或客户端设备获取信息在HTTP请求期间，告诉您的应用程序的类型和级别支持浏览器或客户端设备优惠。反过来的对象使用强类型公开有关浏览器功能的信息属性和通用名称 - 值字典。

private void Button1_Click(object sender, System.EventArgs e)
{
    System.Web.HttpBrowserCapabilities browser = Request.Browser;
    string s = "Browser Capabilities\n"
        + "Type = "                    + browser.Type + "\n"
        + "Name = "                    + browser.Browser + "\n"
        + "Version = "                 + browser.Version + "\n"
        + "Major Version = "           + browser.MajorVersion + "\n"
        + "Minor Version = "           + browser.MinorVersion + "\n"
        + "Platform = "                + browser.Platform + "\n"
        + "Is Beta = "                 + browser.Beta + "\n"
        + "Is Crawler = "              + browser.Crawler + "\n"
        + "Is AOL = "                  + browser.AOL + "\n"
        + "Is Win16 = "                + browser.Win16 + "\n"
        + "Is Win32 = "                + browser.Win32 + "\n"
        + "Supports Frames = "         + browser.Frames + "\n"
        + "Supports Tables = "         + browser.Tables + "\n"
        + "Supports Cookies = "        + browser.Cookies + "\n"
        + "Supports VBScript = "       + browser.VBScript + "\n"
        + "Supports JavaScript = "     + 
            browser.EcmaScriptVersion.ToString() + "\n"
        + "Supports Java Applets = "   + browser.JavaApplets + "\n"
        + "Supports ActiveX Controls = " + browser.ActiveXControls 
              + "\n"
        + "Supports JavaScript Version = " +
            browser["JavaScriptVersion"] + "\n";

    TextBox1.Text = s;
}

如何使用asp.net知道兼容性是打开还是关闭（c＃）
