Question

Is there a way to reply to the user’s wall comments using the Facebook C# SDK? I’m using following code for wall posting:

var fb = new FacebookClient(facebookOAuthResult.AccessToken);
dynamic parameters = new ExpandoObject();
parameters.message = "test";
dynamic postresult = fb.Post("me/feed", parameters);

I hope I’m understanding this question correctly. I’m assuming this is the use case:

1. User posts a status update(the ID of this post is “12345”)
2. User’s friend writes a comment for that status update
3. User writes on a comment on the status update made in Step.1

try  
{  
    String statusUpdateID = "12345";  
    fb.Post(String.Format("/{0}/comments", statusUpdateID), parameters);  
}  
catch (FacebookOAuthException e)  
{  
    //this exception is thrown if your comment fails to post  
}

That should do it! Of course, make sure that statusUpdateID is set to the actual ID of the message you want to comment on.

Also, you do NOT need to store the return value of ‘fb.Post(),’ it is the ID of the comment you just made.
