Asp.net identifies client browsers or operating systems, and asp.net clients

Asp.net identifies client browsers or operating systems, and asp.net clients

1. Use UserAgent

Protected void Page_Load (object sender, EventArgs e) {// verification terminal string agent = Request. headers ["User-Agent"]; if (choose_net (agent) {Response. redirect ("/mobile/") ;}/// verification terminal 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.wapja.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 ("agent")>-1 | // another unknown browser (Web based "Wapalyzer") userAgent. indexOf ("plugin")>-1 | userAgent. indexOf ("Android")>-1 | userAgent. indexOf ("mozilla")>-1) {return true;} else {return false ;}}

2. Consider asp.net mvc

There is a template for mobile.

3. Get the browser attributes

Copy codeThe Code is as follows: HttpBrowserCapabilities bc = Request. browser; Response. write ("<script language = 'javascript '> alert ('" + bc. browser + "'); </script> ");

4. js judgment

<Script type = "text/javascript"> var bro = navigator. userAgent; // alert (bro); // alert (bro. indexOf ("Windows Phone"); // iPad browser navigator. userAgent (including iPad) if (bro. indexOf ("NetFront")> 0 | bro. indexOf ("UCWEB")> 0 | bro. indexOf ("iPhone")> 0 | bro. indexOf ("Windows CE")> 0 | bro. indexOf ("MIDP-2.0")> 0 | bro. indexOf ("Android")> 0 | bro. indexOf ("Opera Mini")> 0 | bro. indexOf ("SymbianOS")> 0 | bro. indexOf ("Windows Phone")> 0) {window. open ("Wap1/Index. aspx "," _ top ");} // else if (bro. indexOf ("Windows NT")> 0) {// window. open ("NewWeb/default.html", "_ top"); //} else {window. open ("NewWeb/default.html", "_ top") ;}</script>

Let's take a look at how to obtain client information on the PC end.

/// <Summary> /// obtain the operating system name /// </summary> /// <param name = "userAgent"> </param> // <returns> </returns> private string GetOSNameByUserAgent (string userAgent) {string osVersion = "unknown"; 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"; elseosVersion = "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 ;}

Basically, it's quite complete. Let's make your choice based on your needs.
