Use useragent to determine smart phones (devices, Android, and iOS)

Recently, I have been upgrading my company's mobile phone site and made a touch-screen version dedicated. after doing so, I tried to use the agent to determine the corresponding smartphone device and then jumped to the new mobile phone site.

After unremitting efforts, I finally collected the agent of comprehensive smart devices, and then wroteProgram, DirectlyCodeHope to help you

 

 ///  <Summary>  
  ///  Determine whether the agent is a smartphone
  ///  </Summary>  
  ///  <Returns> </returns>  
     Public   Static   Bool Checkagent ()
{
 Bool Flag = False ;

 String Agent = httpcontext. Current. Request. useragent;
 String [] KEYWORDS = { "  Android  " , "  IPhone " , "  IPod  " , "  IPad  " , "  Windows Phone  " , "  Mqqbrowser  " };

 //  Exclude Windows Desktop 
              If (! Agent. Contains ( "  Windows NT  " ) | (Agent. Contains ( "  Windows NT  " ) & Agent. Contains ( "  Compatible; MSIE: 9.0;  " )))
{
 //  Exclude Apple Desktop  
                 If (! Agent. Contains ( "  Windows NT  " )&&! Agent. Contains ( "  Macintosh  " ))
{
 Foreach ( String Item In Keywords)
{
 If (Agent. Contains (item ))
{
Flag = True ;
 Break ;
}
}
}
}

 Return Flag;
}

Code explanation:

1 .! Agent. Contains ("Windows NT ")&&! Agent. Contains ("Macintosh") exclude windows and Apple desktop systems

2. "android", "iPhone", "iPod", "iPad", "Windows Phone", and "mqqbrowser" are keywords used to judge the agent of a smart device.

3. The mqqbrowser is the QQ mobile phone browser. The agent of the QQ mobile phone is special, so it is determined separately.

 

The following are some of the agents that we have collected. It is difficult to find so many smart devices:
