Geolocation is a great way to put relevant content to your web visitors and it is a technology that can be used in almost any application you can think of.
In this tutorial, we use the IP2Location.io IP Geolocation API to lookup geolocation information from the visitor’s IP address. Instead of loading the full database, you can also lookup IP address via our API.
Below are the sample codes written in C# to query and display user’s geolocation information.
