有人可以建议一种有效的方法来获得＆＃34;价值＆＃34; JArray使用Newtonsoft JSON API吗？

Answer 1

这是我尝试过的，它有效。如果有人可以改进它，请随意。

private dynamic GetFirstObject(string response)
{
    dynamic firstObject = null;
    if (!String.IsNullOrEmpty(response))
    {
        JArray arrResponse = JArray.Parse(response) as JArray;
        dynamic dyResponse = arrResponse[0];
        string strValue = JsonConvert.SerializeObject(dyResponse.Value);
        JArray arrValueList = JArray.Parse(strValue);

        if (arrValueList.Count > 0)
        {
            firstObject = arrValueList[0];
        }
    }
    return firstObject;
}

Answer 2

使用DeserializeObject

var myObject = JsonConvert.DeserializeObject<List<ResponseObject>>(json);
var OrderID = myObject[0].Value[0].OrderID;

以下是您需要的课程：

public class ResponseObject
{
    public string Key { get; set; }
    public List<Value> Value { get; set; }
}

public class Value
{
    public int OrderID { get; set; }
    public int OrderItemID { get; set; }
    public int ProgramID { get; set; }
    public string ProgramName { get; set; }
    public string ProgramDescription { get; set; }
    public string ScheduleDate { get; set; }
    public string SubmitOrderRequestDate { get; set; }
    public string OrderTypeName { get; set; }
    public string OrderTypeDescription { get; set; }
    public object ProductID { get; set; }
    public object ProductName { get; set; }
    public object ProductDescription { get; set; }
    public object ProductHTMLTitle { get; set; }
    public string EditionName { get; set; }
    public int EditionID { get; set; }
    public string EditionDescription { get; set; }
    public object SpecialInstruction { get; set; }
    public string OrderDeliveryTypeName { get; set; }
    public string OrderDeliveryTypeDescription { get; set; }
    public string OrderItemStatusName { get; set; }
    public string OrderItemStatusDescription { get; set; }
    public string EditionStatus { get; set; }
    public string EditionStatusDescription { get; set; }
    public object OrderItemDeliveryStatusName { get; set; }
    public object OrderItemDeliveryStatusDescription { get; set; }
    public int OrderItemQuantity { get; set; }
    public object OrderItemDeliveryQuantityRequested { get; set; }
    public object OrderItemDeliveryID { get; set; }
    public object UploadedFlag { get; set; }
    public object AccessCode { get; set; }
    public object Created { get; set; }
    public object UseSecureBrowserFlag { get; set; }
    public string ExamName { get; set; }
    public int CohortID { get; set; }
    public string CohortName { get; set; }
    public int StudentCount { get; set; }
    public object ExamTypeProgramTypeID { get; set; }
    public int OrderItemApplicationID { get; set; }
    public object DBLockedByUserName { get; set; }
    public object AutoCodeEditionFlag { get; set; }
    public object WorkflowName { get; set; }
    public object WorkflowStatus { get; set; }
    public bool UseLastSyllabusFlag { get; set; }
    public int SyllabusID { get; set; }
    public object AssessmentTypeName { get; set; }
}
