Custom Like using Facebook C# API

I'm using Facebook C# API and I want to create a custom "Like" action, allowing the user to like objects outside of Facebook.

The user will be allowed to "Like" a custom object, like an Apple or a Book, and the app has to post this information in the user timeline.

I've tried

dynamic res = fb.Post("me/og.likes", new
                    {
                        message = "My first like  post using Facebook SDK for .NET"
                    });

But this gives me the following FacebookApiException exception

(Exception - #1611072) The action you're trying to publish is invalid because it does not specify any reference objects. At least one of the following properties must be specified: object.

But if I try

dynamic res = fb.Post("me/og.likes", new
                    {
                        object="http://samples.ogp.me/226075010839791"
                    });

it doesn't even compile, since object is a reserved word on C#.

What should I do? Is it possible?

Solution

Try escape using @:

dynamic res = fb.Post("me/og.likes", new
                    {
                        @object="http://samples.ogp.me/226075010839791"
                    });

EDIT: For other special characters you should be able to use a dictionary instead of a anonymous typed object:

var postInfo = new Dictionary<string, object>();
postInfo.Add("fb:explicitly_shared", "your data");

dynamic res = fb.Post("me/og.likes", postInfo);
