Question

I read on the facebook documentation (here) that you can force a rescrape of your object to update it on a user’s timeline.

Updating Objects

When modifying Open Graph objects, you will need to tell Facebook’s
scraper to rescrape your page to pull in the updated information.
There are a couple different ways to have your object re-scraped.

More automated by using the “scrape=true” POST parameter. Make a POST
call to https://graph.facebook.com/?id={id}&scrape=true where {id} is
the object id or the url of the object. The response is a JSON object
with the data scraped for the url.

So how wold you go about this using the C# SDK?

Thanks in advance,
Chad

EDIT: I tried the following as a quick and dirty test:

        Dim fbData As FacebookSDKInterface = New FacebookSDKInterface()
        Dim fb As Facebook.FacebookClient = New Facebook.FacebookClient(fbData.FacebookAccessToken)

        Dim fbURL As String = NavigateURL() & "?ID=" & GetPathFromDyno(e.Keys(0))

        Dim dicFBPostParams As New Dictionary(Of String, String)
        dicFBPostParams.Add("id", fbURL)
        dicFBPostParams.Add("scrape", "true")


        fb.Post(dicFBPostParams)

But I got this error:

System.Reflection.TargetParameterCountException: Parameter count mismatch. at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) at System.Reflection.RuntimePropertyInfo.GetValue(Object obj, BindingFlags invokeAttr, Binder binder, Object[] index, CultureInfo culture) at System.Reflection.RuntimePropertyInfo.GetValue(Object obj, Object[] index) at Facebook.FacebookClient.ToDictionary(Object parameters, IDictionary`2& mediaObjects, IDictionary`2& mediaStreams) at Facebook.FacebookClient.PrepareRequest(HttpMethod httpMethod, String path, Object parameters, Type resultType, Stream& input, Boolean& containsEtag, IList`1& batchEtags) at Facebook.FacebookClient.Api(HttpMethod httpMethod, String path, Object parameters, Type resultType) at Facebook.FacebookClient.Post(String path, Object parameters) at Facebook.FacebookClient.Post(Object parameters) at Incite.Modules.TheDynoRoom.MyGarage.dtlDyno_ItemUpdated(Object sender, DetailsViewUpdatedEventArgs e) in C:\Users\Chad\Documents\Incite Systems\Development\Web Sites\DNN_Dyno\DesktopModules\Incite\The Dyno Room\Controls\MyGarage.ascx.vb:line 1156
