How to deserialize a pseudo-json array into c#


I might be silly, but I'm stuck on this one.

I'm coding in c# and attempting to parse a JSON string into an object. The problem is that the string contains a data-field which I call a pseudo-array. It isn't a real array, because it is missing the []'s....

I really don't want to create an object with 500 properties just to cater for what I assume to be a bug in the API's JSON response - but how on earth do I deserialize this into c# objects?

Below is the sample JSON from the API's documentation page. (I don't own the API - so I can't change the JSON)

Any advice will be appreciated. Thanks k

Solution

  • The data property of your JSON object is an associative array. You need to access each element by the appropriate key (in this case a numeric string)

    // convert from a String into a JObject
    var data = JObject.Parse(json);
    
    // access single property
    Response.Write(data["data"]["71489"]);
    Response.Write(data["data"]["140141"]);
    
    // iterate all properties
    foreach (JProperty prop in data["data"])
    {
        Response.Write(prop.Name + ": " + prop.Value);
    
        // Also possible to access things like:
        // - prop.Value["air_by_date"]
        // - prop.Value["cache"]["banner"]
        // - prop.Value["cache"]["poster"]
        // - prop.Value["language"]
    }
