ua_parser C# Library

This is the CSharp implementation of ua-parser. You can find the latest binaries on NuGet here.

Build status

The implementation uses the shared regex patterns and overrides from regexes.yaml (found in uap-core). The assembly embeds the latest regex patterns (enabled through a git submodule) which are loaded into the default parser. You can create a parser with more updated regex patterns by using the static methods on Parser to pass in specific patterns in yaml format.

Build and Run Tests:

Make sure you pull down the submodules that includes the yaml files (otherwise you won't be able to compile):

git submodule update --init --recursive

You can then build and run the tests by invoking the build.bat script


Update the embedded regexes

To pull the latest regexes into the project:

cd uap-core
git pull origin master


  using UAParser;


  string uaString = "Mozilla/5.0 (iPhone; CPU iPhone OS 5_1_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B206 Safari/7534.48.3";

  // get a parser with the embedded regex patterns
  var uaParser = Parser.GetDefault();

  // get a parser using externally supplied yaml definitions
  // var uaParser = Parser.FromYaml(yamlString);

  ClientInfo c = uaParser.Parse(uaString);

  Console.WriteLine(c.UserAgent.Family); // => "Mobile Safari"
  Console.WriteLine(c.UserAgent.Major);  // => "5"
  Console.WriteLine(c.UserAgent.Minor);  // => "1"

  Console.WriteLine(c.OS.Family);        // => "iOS"
  Console.WriteLine(c.OS.Major);         // => "5"
  Console.WriteLine(c.OS.Minor);         // => "1"

  Console.WriteLine(c.Device.Family);    // => "iPhone"
