What's Covered

This tutorial illustrates how to return a match for a Device Id. It shows how to first get the Device Id from a match, then get a match for that Device Id and return the value of the IsMobile property. This can be useful to look at devices that have already been matched at a previous date.

Code and Explanation

Match for device id example of using 51Degrees device detection. The example shows how to:

  1. Set the data set for the 51Degrees detector

    string fileName = args[0];
    DataSet dataSet = StreamFactory.Create(fileName, false);

  • Instantiate the 51Degrees device detection provider with these settings

    Provider provider = new Provider(dataSet);
  • Produce a match for a single device id

    match = provider.MatchForDeviceId(deviceId);
  • Extract the value of the IsMobile property

    IsMobile = match["IsMobile"].ToString();
    This tutorial assumes you are building this from within the 51Degrees Visual Studio solution. Running the executable produced inside Visual Studio will ensure all the command line arguments are preset correctly. If you are running outside of Visual Studio, make sure to add the path to a 51Degrees data file as an argument.

  • Summary

    In this tutorial you have seen how to use the detector to retrieve the IsMobile property for a pre-defined Device ID string. The example can easily be modified to retrieve the value of any other property. Premium and Enterprise data files provide considerably more properties such as IsCrawler , PriceBand , HardwareVendor and ScreenInchesWidth . For a full list of properties and the data files they exist in please see the Property Dictionary .
