(C# UWP/WinRT) JSON: Array of Objects

Here we have a JSON object that contains an array, where each element in the array is a JSON object. This example demonstrates how to access the objects contained within an array.

{ 
  "employees":[
    {"firstName":"John", "lastName":"Doe"},
    {"firstName":"Anna", "lastName":"Smith"},
    {"firstName":"Peter","lastName":"Jones"}
  ]
}

Chilkat.JsonObject json = new Chilkat.JsonObject();

// This is the above JSON with whitespace chars removed (SPACE, TAB, CR, and LF chars).
// The presence of whitespace chars for pretty-printing makes no difference to the Load
// method. 
string jsonStr = "{\"employees\":[{\"firstName\":\"John\", \"lastName\":\"Doe\"},{\"firstName\":\"Anna\", \"lastName\":\"Smith\"},{\"firstName\":\"Peter\",\"lastName\":\"Jones\"}]}";

bool success = json.Load(jsonStr);
if (success != true) {
    Debug.WriteLine(json.LastErrorText);
    return;
}

// Get the "employees" array.
Chilkat.JsonArray employees = json.ArrayOf("employees");
if (json.LastMethodSuccess == false) {
    Debug.WriteLine("employees member not found.");
    return;
}

// Iterate over each employee, getting the JSON object at each index.
int numEmployees = employees.Size;
int i = 0;
while (i < numEmployees) {

    Chilkat.JsonObject empObj = employees.ObjectAt(i);

    Debug.WriteLine("employee[" + Convert.ToString(i) + "] = " + empObj.StringOf("firstName") + " " + empObj.StringOf("lastName"));

    i = i + 1;
}
