C# Open Graph Example

The following C# .NET example shows how a user might use Opengraph.io to get a website’s title, description, and icon given a URL. This example makes use of .NET system libraries and NewtonSoft’s popular JSON.NET library to retrieve and parse results from the OpenGraph.io API. The need to gather information like this is very common when creating an application that posts content onto social media sites such as Facebook (see screenshot to the right) or Linkedin where the user wants to control how the link is displayed.
