(C# UWP/WinRT) Loading and Parsing a JSON Array

A JSON array is JSON that begins with "[" and ends with "]". For example, this is a JSON array that contains 3 JSON objects.

[{"name":"jack"},{"name":"john"},{"name":"joe"}]

A JSON object, however, is JSON that begins with "{" and ends with "}". For example, this JSON is an object that contains an array.

{"pets":[{"name":"jack"},{"name":"john"},{"name":"joe"}]}

This example shows how loading a JSON array is different than loading a JSON object.

string strJsonArray = "[{\"name\":\"jack\"},{\"name\":\"john\"},{\"name\":\"joe\"}]";

string strJsonObject = "{\"pets\":[{\"name\":\"jack\"},{\"name\":\"john\"},{\"name\":\"joe\"}]}";

// A JSON array must be loaded using JsonArray:
Chilkat.JsonArray jsonArray = new Chilkat.JsonArray();
jsonArray.Load(strJsonArray);

// Examine the values:
int i = 0;
while (i < jsonArray.Size) {
    Chilkat.JsonObject jsonObj = jsonArray.ObjectAt(i);
    Debug.WriteLine(Convert.ToString(i) + ": " + jsonObj.StringOf("name"));

    i = i + 1;
}

// Output is:

// 	0: jack
// 	1: john
// 	2: joe

// A JSON object must be loaded using JsonObject
Chilkat.JsonObject jsonObject = new Chilkat.JsonObject();
jsonObject.Load(strJsonObject);

// Examine the values:
i = 0;
int numPets = jsonObject.SizeOfArray("pets");
while (i < numPets) {
    jsonObject.I = i;
    Debug.WriteLine(Convert.ToString(i) + ": " + jsonObject.StringOf("pets[i].name"));
    i = i + 1;
}

// Output is:

// 	0: jack
// 	1: john
// 	2: joe
