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

  1. Instantiate the 51Degrees device detection provider. 

    										
provider = FiftyOneDegreesPatternV3.NewProvider(dataFile)
  2. Produce a match for a single device id 

    										
match = provider.GetMatchForDeviceId(deviceId)
  3. Extract the value of the IsMobile property 

    										
match.GetValue("IsMobile")
This example assumes you have the 51Degrees Go API installed correctly.

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 .
