Question

Here is the code I am using to get Facebook friend list, the class

public class FBUser
{
    public long Id { get; set; }
    public string Username { get; set; }
    public string Name { get; set; }
    public string Link { get; set; }
    public string Picture { get; set; }

    // empty constructor
    public FBUser()
    { }
}

the list class

public class FbFriendList
{
    public WcdyList<FBUser> Data { get; set; }
}

and here is the method I am using to get the friend list:

try
{   
    FacebookClient client = new FacebookClient(accesstoken);
        FbFriendList myfriends = client.Get<FbFriendList>("me/friends?fields=id,name,username,picture,link");

        if (myfriends.Data.Count > 0) return myfriends.Data;
        else return null;
}
catch (Exception ex) { }

myfriends is returning the data object null, can you please tell me what I am doing wrong here?

Answer 1

You can use code like this to get the friends info

FacebookClient client = new FacebookClient(accesstoken);
dynamic result = app.Get("me/friends?fields=id,name,username,picture,link");

Now you can map the resulting data to your custom classes…

Update:
Seems like you using Data instead of data (you should stick to original names of fields in response)

public class FbFriendList {
  public WcdyList<FBUser> data { get; set; }
}

Update2:
You can loop over the list to get friends details like this:

foreach (dynamic friend in result.data) {
  string friendId = friend.id;
  string friendName = friend.name;
  // etc...
}

Or like this if you not yet on .net4:

var resultData = (IList<object>)result.data;
foreach (var friendObj in resultData) {
  var friend = (IDictionary<string, object>)friendObj;
  string friendId = friend["id"];
  string friendName = friend["name"];
  // etc...
}
