GooglePlusLib .NET Client Library for Google+ API

Every once in a while you come across something useful but incomplete. Such is the case with this GooglePlus.NET library

The GooglePlus.NET library can be found here:

http://www.googleplustips.com/resources/3332-NET-Library-Google-APIs-released.aspx

Tony John, the author, says "You are welcome to use the GooglePlusLib.NET client library as you like. You can use this library to develop applications and distribute it with your applications."

The only problem is, he only provides the downloadable Assembly and no source code is to be found. That's not good enough for me, so I decompiled it, fixed up the code, added some XML documentation, and added a sample Test Console App that exercises some of the methods. The nice thing about this library is that it deserializes all the API JSON into .NET Classes which makes working with the API much cleaner. Here is some sample code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using GooglePlusLib.NET;

namespace GooglePlusAPI
{
    class Program
    {
      static  string profileId = "114085939943834183247"; // Peter Bromberg
      private static string apiKey = "";    // put your API Key here
        static void Main(string[] args)
        {
            if (apiKey.Length == 0) throw new InvalidOperationException("Requires apiKey: https://code.google.com/apis/console/b/0/");
            GooglePlusAPIHelper apiHelper = new GooglePlusAPIHelper(profileId, apiKey);

         // var people=apiHelper.SearchPeople("Peter Bromberg");
       //  var acts=   apiHelper.SearchActivities("ASP.NET");
        // var people   apiHelper.ListPeopleByActivity();
        // GPlusComments comments=    apiHelper.ListComments( string activityId);
        // GPlusACtivities activities=    apiHelper.ListActivities();
       //  GPlusPerson person=  apiHelper.GetPerson();
        // GPlusComment comment=    apiHelper.GetComment( string commentId);
       //  GPlusActivity activity=   apiHelper.GetActivity( string activityId);

GPlusActivities activities = apiHelper.ListActivities();

            int total = 0;
while (!string.IsNullOrEmpty(activities.nextPageToken))
{
  
    foreach (GPlusActivity activity in activities.items)
    {
        total += activities.items.Length;
        string titlei = activity.title;
        string plusDescription = activity.plusObject.content;
        string pubDate = activity.published.ToShortDateString();

       Console.WriteLine(pubDate );
       Console.WriteLine(titlei);
           Console.WriteLine( plusDescription);
       Console.WriteLine("===================================================================");


        if (activity.plusObject.attachments == null)
            continue;

        foreach (Attachment attachment in activity.plusObject.attachments)
         {
             if (attachment.objectType == "article")
            {
                string url = attachment.url;
                string title = attachment.displayName;
                string content = attachment.content;
            }
        }
    }

    activities = apiHelper.ListActivities(activities.nextPageToken);
    foreach (var act in activities.items)
    {
       Console.WriteLine( act.title);
    }
}

Console.WriteLine("ITEMS:" + total.ToString());
           Console.ReadLine();
        }
    }
}


This library currently covers all the methods available in the Google+ API. With this source code, you are in a position to be able to easily update it when the API is enhanced. It also provides the nextPageToken which allows you to handle paging of results. You have everything in this library that you need, for example, to build an entire web site around the Google+ API including searching for people, activities, comments, attachments (articles or images) and so on. You can get your own API key here.

You can download the full Visual Studio 2010 Solution here.
