如何从JSON文件反序列化NewtenSoft中的子节点

Question

我读了一个JSON文件，请参阅下面的当前格式。反序列化按预期工作。现在，客户向我提供了另一个格式略有不同的文件。该应用程序将来必须适应这两种格式。 在当前格式中，我基本上读取了值复制字段，我必须基本上以新格式执行相同操作。在新格式中，复制字段位于名为Assays的新节点内。我不确定如何读取子节点。

**Current Format**
    "Orders": [
            {
                "Rack": "0015",
                "SampleType": "Calibrator",
                "Position": 1,
                                                    "CalMaterialLotNumber" : "08559LF00",
                                                    "CalMaterialExpirationDate" : "07-31-2012",
                                                    "LevelName" : "Cal 1",
                "AssayNumber": 149,
                        "AssayVersion": 5,

                "Replicate": 3,
                                    "Track": 1,
                        "Lane": 1,

                "ReagentSerialNumber": 65000,
                "


    **New Format**

处理JSON文件的方法

public static KeyValuePair<bool, int> CyclesCompleted(string fileName)
    {
        int cyclesCompleted = 0;
        JavaScriptSerializer ser = jss();
        bool isValid = true;
        try
        {
            //Run Newtonsoft JSON deserializer
            var deserialized = JsonConvert.DeserializeObject<CategoryTypeColl>(LoadTextFromFile(fileName));
            CategoryTypeColl ctl = deserialized;

            //CategoryTypeColl ctl = ser.Deserialize<CategoryTypeColl>(LoadTextFromFile(fileName));

            if (ctl != null)
            {
                List<CategoryType> collection = (from item in ctl.MCCOrders
                                                 select item).ToList();

                foreach (var replicates in collection)
                {
                    cyclesCompleted = cyclesCompleted + replicates.Replicate;
                }
            }
        }
        catch
        {
            isValid = false;
        }
        return new KeyValuePair<bool, int>(isValid, cyclesCompleted);
    }
