asp.net实现识别客户端浏览器或操作系统

1、通过 UserAgent

protected void Page_Load(object sender, EventArgs e)
  {
    //验证终端
    string agent = Request.Headers["User-Agent"];
    if (choose_net(agent))
    {
      Response.Redirect("/mobile/");
    }
  }

  //验证终端
  public bool choose_net(String userAgent)
  {
    if (userAgent.IndexOf("Noki") > -1 || // Nokia phones and emulators  
  userAgent.IndexOf("Eric") > -1 || // Ericsson WAP phones and emulators  
  userAgent.IndexOf("WapI") > -1 || // Ericsson WapIDE 2.0  
  userAgent.IndexOf("MC21") > -1 || // Ericsson MC218  
  userAgent.IndexOf("AUR") > -1 || // Ericsson R320  
  userAgent.IndexOf("R380") > -1 || // Ericsson R380  
  userAgent.IndexOf("UP.B") > -1 || // UP.Browser  
  userAgent.IndexOf("WinW") > -1 || // WinWAP browser  
  userAgent.IndexOf("UPG1") > -1 || // UP.SDK 4.0  
  userAgent.IndexOf("upsi") > -1 || //another kind of UP.Browser  
  userAgent.IndexOf("QWAP") > -1 || // unknown QWAPPER browser  
  userAgent.IndexOf("Jigs") > -1 || // unknown JigSaw browser  
  userAgent.IndexOf("Java") > -1 || // unknown Java based browser  
  userAgent.IndexOf("Alca") > -1 || // unknown Alcatel-BE3 browser (UP based)  
 
 
  userAgent.IndexOf("MITS") > -1 || // unknown Mitsubishi browser  
  userAgent.IndexOf("MOT-") > -1 || // unknown browser (UP based)  
  userAgent.IndexOf("My S") > -1 ||// unknown Ericsson devkit browser   
  userAgent.IndexOf("WAPJ") > -1 ||//Virtual WAPJAG www.wapjag.de  
  userAgent.IndexOf("fetc") > -1 ||//fetchpage.cgi Perl script from www.wapcab.de
 
  
  userAgent.IndexOf("ALAV") > -1 || //yet another unknown UP based browser  
  userAgent.IndexOf("Wapa") > -1 || //another unknown browser (Web based
 
"Wapalyzer")  
  userAgent.IndexOf("UCWEB") > -1 || //another unknown browser (Web based
 
"Wapalyzer")  
  userAgent.IndexOf("BlackBerry") > -1 || //another unknown browser (Web
 
based "Wapalyzer")   
  userAgent.IndexOf("J2ME") > -1 || //another unknown browser (Web based
 
"Wapalyzer")
  userAgent.IndexOf("Oper") > -1 ||
  userAgent.IndexOf("Android") > -1 ||
      userAgent.IndexOf("mozilla") > -1)
    {
      return true;
    }
    else
    {
      return false;
    }
  }

2.考虑asp.net mvc

里面有for mobile的模版

3.获取浏览器的属性

复制代码 代码如下:HttpBrowserCapabilities bc=Request.Browser; Response.Write("");

 4.js判断

我们再来看下如何获取PC端的客户端信息呢

/// 

/// 获取操作系统的名字
/// 
/// 
/// 
private string GetOSNameByUserAgent(string userAgent)
{
	string osVersion = "未知";
 
	if (userAgent.Contains("NT 10.0"))
	{
		osVersion = "Windows 10";
	}
	else if (userAgent.Contains("NT 6.3"))
	{
		osVersion = "Windows 8.1";
	}
	else if (userAgent.Contains("NT 6.2"))
	{
		osVersion = "Windows 8";
	}
	else if (userAgent.Contains("NT 6.1"))
	{
		osVersion = "Windows 7";
	}
	else if (userAgent.Contains("NT 6.1"))
	{
		osVersion = "Windows 7";
	}
	else if (userAgent.Contains("NT 6.0"))
	{
		osVersion = "Windows Vista/Server 2008";
	}
	else if (userAgent.Contains("NT 5.2"))
	{
		if (userAgent.Contains("64"))
			osVersion = "Windows XP";
		else
			osVersion = "Windows Server 2003";
	}
	else if (userAgent.Contains("NT 5.1"))
	{
		osVersion = "Windows XP";
	}
	else if (userAgent.Contains("NT 5"))
	{
		osVersion = "Windows 2000";
	}
	else if (userAgent.Contains("NT 4"))
	{
		osVersion = "Windows NT4";
	}
	else if (userAgent.Contains("Me"))
	{
		osVersion = "Windows Me";
	}
	else if (userAgent.Contains("98"))
	{
		osVersion = "Windows 98";
	}
	else if (userAgent.Contains("95"))
	{
		osVersion = "Windows 95";
	}
	else if (userAgent.Contains("Mac"))
	{
		osVersion = "Mac";
	}
	else if (userAgent.Contains("Unix"))
	{
		osVersion = "UNIX";
	}
	else if (userAgent.Contains("Linux"))
	{
		osVersion = "Linux";
	}
	else if (userAgent.Contains("SunOS"))
	{
		osVersion = "SunOS";
	}
	else
	{
		osVersion = HttpContext.Current.Request.Browser.Platform;
	}
	return osVersion;
}

基本上很全了，小伙伴们根据需求自由选择吧
