1, through useragent

protected void Page_Load (object sender, EventArgs e) {//authentication terminal string agent = request.headers["User-agent"];
    if (choose_net (agent)) {Response.Redirect ("/mobile/"); }//Verify terminal public bool Choose_net (String useragent) {if Useragent.indexof ("Noki") >-1 | |//Nokia Phone S 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.")

2. Consider asp.net mvc

With a for mobile template inside

3. Get the properties of the browser

Copy Code code 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.indexo F ("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 get the client information on the PC side.

<summary>///Get the name of the operating system///</summary>///<param name= "useragent" ></param>///<returns&
 
	Gt;</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 (")") OSVersion = "Windows XP";
	else OSVersion = "Windows Server 2003";
	else if (useragent.contains ("NT 5.1")) {osversion = "Windows XP";

	else if (useragent.contains) {osversion = "Windows 98";

	else if (Useragent.contains ("SunOS")) {osversion = "SunOS";
	else {osversion = HttpContext.Current.Request.Browser.Platform;
return osversion; }
