Question

Trying to execute search on Facebook for pages

    if (sq.ObjectType.Equals("page"))
    {
        searchPath = "/search";

        req.q = sq.Query;
        req.type = sq.ObjectType;

    }

    dynamic results = FBClient_.Get(req);

And I can’t figure out how to parse results.
I cant just simple loop through them.

and I can’t see the structure either since it’s dynamic object
Somewhere down the line it has this structure:

{
   "data": [
      {
         "name": "Platform-3",
         "category": "Health/medical/pharmacy",
         "id": "362034114769"
      },
      {
         "name": "Platform Expos",
         "category": "Product/service",
         "id": "521000451259682"
      },
      {
         "name": "eXo Platform",
         "category": "Software",
         "id": "152603664817327"
      },
      {
         "name": "Platform 28",
         "category": "Bar",
         "id": "104411956289378"
      },
}

but how to get it I’m not sure. How do I convert it into readable format?

Answer 1

Here are some mappings.

objects => IDictionary<string, object> or IDictionary<string, dynamic>
arrays => IList<object> or IList<dynamic>
number => long if whole number, double if have decimal values
string => string
boolean => bool

So in your case you could do this.

dynamic result = fb.Get("...")
foreach(var data in result.data) {
    var name = data.name;
    var category = data.category;
    var id = data.id
}

Since result.data is dynamic which is actually IList<object> you can use foreach on it. You could also try this too.

dynamic result = fb.Get("...")
IList<dynamic> data = result.data;
foreach(var d in data) {
    string name = d.name;
    string category = d.category;
    string id = d.id
}

Or you strongly typed.

public class SearchResults {
    public IList<SearchResult> data { get; set;}
}

public class SearchResult {
    public string id { get; set; }
    public string name { get; set; }
    public string category { get; set; }
}

var result = fb.Get<SearchResults>(...)

If you want to follow C# naming standards use DataContract and DataMember.

[DataContract]
public class SearchResults {
    [DataMember(Name = "data")]
    public IList<SearchResult> Data { get; set;}
}

[DataContract]
public class SearchResult {
    [DataMember(Name = "id")]
    public string Id { get; set; }

    [DataMember(Name = "Name")]
    public string Name { get; set; }

    [DataMember(Name = "Category")]
    public string Category { get; set; }
}
