Are you a .NET developer looking for a .NET CLient library to develop cool applications using Google+ data? Here is a .NET library, developed using C#. You can download the .NET Library from here and use it to develop applications.

We are excited to announce the release of GooglePlusLib, a .NET library for Google+ APIs.

Google announced the version 1 of Google+ APIs couple of days ago. As usual, Google released the APIs along with a couple of client libraries, including .NET client library. However, the client libraries released by Google have some learning curve since the usage is not in the native .NET programming style.

Here is a .NET client library we developed for Google+ APIs. They are very easy to use in your applications.


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.

Download GooglePlusLib.NET client library

You can download the GooglePlusLib.NET from here.

How to use the GooglePlusLib.NET?

Our .NET client library is very easy to use in your .NET applications. See the sample code below, which demonstrates how to consume the current version (V. 1) of Google+ APIs:

string profileId = "Use a valid Google+ profile id here";
string apiKey = "Use a valid Google API Key here";
// You can get an API Key here:

GooglePlusAPIHelper apiHelper = new GooglePlusAPIHelper(profileId, apiKey);

GPlusActivities activities = apiHelper.ListActivities("eJx9Uj1IAzEUfglXeuASxbWQRX");

GPlusActivity activity = apiHelper.GetActivity("z13rvzzy2lmtj3p0a22md1c4nyrdufrxv04");

GPlusActivities activities2 = apiHelper.SearchActivities("Windows 8");

GPlusPerson person = apiHelper.GetPerson();

GPlusPeople people = apiHelper.SearchPeople("windows 8 club");

GPlusComments people2 = apiHelper.ListComments("z120yhh54qrbsn5tr22rtjbiqr3mh1qp504");

GPlusComment comment = apiHelper.GetComment("2HOqDyvQVCrbz47vK_w9nSrRYnS");

C# Sample code to iterate through the Google+ API result set

Here is some sample code that demonstrate how to navigate through the result set and fetch next subsequent set of records from Google+

GooglePlusAPIHelper apiHelper = new GooglePlusAPIHelper(profileId, apiKey]);

GPlusActivities activities = apiHelper.ListActivities();

while (!string.IsNullOrEmpty(activities.nextPageToken))
foreach (GPlusActivity activity in activities.items)
string plusDescription = activity.plusObject.content;

if (activity.plusObject.attachments == null)

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);

As Google continues to develop and release more APIs, we will be updating our client library.
