DeviceDetector.NET 4.3.0

DeviceDetector.NET

Description

The Universal Device Detection library for .NET that parses User Agents and detects devices (desktop, tablet, mobile, tv, cars, console, etc.), clients (browsers, feed readers, media players, PIMs, ...), operating systems, brands and models. This is a port of the popular PHP device-detector library to C#. For the most part you can just follow the documentation for device-detector with no issue.

Usage

Using DeviceDetector.NET with nuget is quite easy. Just add DeviceDetector.NET to your projects requirements. And use some code like this one:

using DeviceDetectorNET;

// OPTIONAL: Set version truncation to none, so full versions will be returned
// By default only minor versions will be returned (e.g. X.Y)
// for other options see VERSION_TRUNCATION_* constants in DeviceParserAbstract class
// add using DeviceDetectorNET.Parser;
DeviceDetector.SetVersionTruncation(VersionTruncation.VERSION_TRUNCATION_NONE);

var dd = new DeviceDetector(userAgent);

// OPTIONAL: Set caching method
// By default static cache is used, which works best within one php process (memory array caching)
// To cache across requests use caching in files or memcache
// add using DeviceDetectorNET.Cache;
dd.SetCache(new DictionaryCache());

// OPTIONAL: If called, GetBot() will only return true if a bot was detected  (speeds up detection a bit)
dd.DiscardBotInformation();

// OPTIONAL: If called, bot detection will completely be skipped (bots will be detected as regular devices then)
dd.SkipBotDetection();

dd.Parse();

if(dd.IsBot()) {
	// handle bots,spiders,crawlers,...
	var botInfo = dd.GetBot();
} else {
	var clientInfo = dd.GetClient(); // holds information about browser, feed reader, media player, ...
	var osInfo = dd.GetOs();
	var device = dd.GetDeviceName();
	var brand  = dd.GetBrandName();
	var model  = dd.GetModel();
}

Instead of using the full power of DeviceDetector it might in some cases be better to use only specific parsers. If you aim to check if a given useragent is a bot and don't require any of the other information, you can directly use the bot parser.

using DeviceDetectorNET.Parser;

var botParser = new BotParser();
botParser.SetUserAgent(userAgent);

// OPTIONAL: discard bot information. Parse() will then return true instead of information
botParser.DiscardDetails = true;

var result = botParser.Parse();

if (result != null) {
    // do not do anything if a bot is detected
    return;
}

// handle non-bot requests

The default regexes directory path can be changed like this:

DeviceDetectorSettings.RegexesDirectory = @"C:\YamlRegexsFiles\";
