While working on a project recently I needed to be able to determine if the user was coming to the ASP.Net site was using a mobile browser. In my particular case, the IsMobileBrowser property didn’t work so I created this code to do it for me, based on the information i gleamed from http://www.zytrax.com/tech/web/mobile_ids.html. Enjoy.

string[] arr = new string[]
{
"Windows CE",
"PlayStation Portable",
"PLAYSTATION 3",
"Symbian OS",
"SonyEricsson",
"Opera Mini",
"SIE",
"Vodafone",
"SEC",
"SAMSUNG",
"SCH",
"240x320",
"MobileExplorer",
"PalmSource",
"PalmOS",
"Smartphone",
"BlackBerry",
"iPhone"
};

foreach (string s in arr) {
if (Context.Request.UserAgent.ToLower().Contains(s.ToLower()))
Response.Redirect("/mobile.aspx");
}
