(C#) Understanding JSON Array vs JSON ObjectThis example explains the difference between a JSON Array and a JSON Object. A JSON Array begins with "[" and ends with "]", whereas a JSON Object begins with "{" and ends with "}". Elements contained in a JSON array are accessed by index, whereas elements in a JSON object are typically accessed by name (but can also be accessed by index).
// A JSON array should be loaded into a Chilkat JSON array, // whereas a JSON object should be loaded into a Chilkat JSON object. // A JSON array may contain objects, and a JSON object may contains arrays, but // it is the top-level (outermost) element that defines whether the JSON // document is an array or an object. // An array begins and ends with "[" ... "]" // An object begins and ends with "{" ... "}" // For example, an array containing 2 objects: string strJsonArray = "[ { \"name\": \"Bill\" }, { \"name\": \"Ted\" } ]"; // Load it into a JSON array. Chilkat.JsonArray jsonA = new Chilkat.JsonArray(); bool success = jsonA.Load(strJsonArray); Debug.WriteLine("number of array elements: " + Convert.ToString(jsonA.Size)); // This is an object containing an array: string strJsonObj = "{ \"characters\": [ \"Bill\", \"Ted\" ] }"; // Load it into a JSON object. Chilkat.JsonObject jsonO = new Chilkat.JsonObject(); success = jsonO.Load(strJsonObj); Debug.WriteLine("number of object members: " + Convert.ToString(jsonO.Size)); |
