Here is my code:

List<string> namesList = new List<string>();
dynamic json1 = JsonConvert.DeserializeObject(data);


Now I'm stuck...
I have two problems: I have to read every name inside objects like

realms/lang/de_DE.lang


The problem is that i don't know the names and on the internet i just found how to read the values inside dynamic json objects and not how to read the name of it...

The second problem is that on another class i have to process all this data and i need the hashes too. Is it convenient to calculate the hash on the moment for every file(there are 675 files) or to pass the hashes as a return?
I already return a list converted to an array of URL's so i don't know how to return both the URL's and the HASH and then process them.
I add to the namelist the value with a foreach loop:

namesList.Add(finalurl);


And then i return this:

return namesList.ToArray();

Answer

You should create classes for deserialization like this:

public class MyClass
{
    [JsonProperty("objects")]
    public IDictionary<string, ObjectValue> Objects { get; set; }
}

public class ObjectValue
{
    [JsonProperty("hash")]
    public string Hash { get; set; }

    [JsonProperty("size")]
    public long Size { get; set; }
}

and then you can get your names like this:

MyClass json = JsonConvert.DeserializeObject<MyClass>(data);
var names = json.Objects.Keys.ToList();
var hash = json.Objects[names[0]].Hash; // Get the hash of the first item

Also don't forget to check if null and other possible errors (no data etc).
