asp.net - 为什么此JSON返回为 "Invalid JSON primitive"？

Question

以下JSON未反序列化。显然是因为保存JSON中的DECIMALS。我该如何解决？

此初始JSON来自服务器且有效:

    {
    "AppropriationAmount": 25000000, 
    "AppropriationHours": 56300, 
    "ArrThreshold": 11, 
    "ClientKey": 24, 
    "Description": 'Find and incarcerate the escaped prisoner', 
    "DirectHours": 50000, 
    "EndDate": '3/31/2011', 
    "EngineeringHours": 4000, 
    "IndirectHours": 2000, 
    "Key": 1589, 
    "Number": '0', 
    "OtherHours": 300, 
    "ProductivityCurveType": 'BurnedEarned', 
    "ProjectManager": 'Doctor Who', 
    "ProjectName": 'Prisoner ZERO', 
    "StartDate": '5/1/2010' 
    }

此后续JSON发送到服务器失败:
一旦用户编辑了表单，数据就会在客户端进行序列化并发送回去……在尝试对JSON进行反序列化时，数据(然后)失败。

    {
    "AppropriationAmount": 56300.00, 
    "AppropriationHours": 25000000.00, 
    "ArrThreshold": 11.00, 
    "ClientKey": , 
    "Description": 'Find and incarcerate the escaped prisoner', 
    "DirectHours": 50000.00, 
    "EndDate": '3/31/2011', 
    "EngineeringHours": 4000.00, 
    "IndirectHours": 2000.00, 
    "Key": 1589, 
    "Number": '0', 
    "OtherHours": 300.00, 
    "ProductivityCurveType": 'BurnedEarned', 
    "ProjectManager": 'Doctor Who', 
    "ProjectName": 'Prisoner ZERO', 
    "StartDate": '5/1/2010' 
    }

此代码引发错误:

    try
    {
        if (!String.IsNullOrEmpty(this.JSON))
        {
            serializer = new JavaScriptSerializer();
            dialog = serializer.Deserialize<ProjectDecorator>(this.JSON);
        }
    }
    catch (Exception ex)
    {
        // The message shows here
    }

引发的错误看起来像:

{"Invalid JSON primitive: ."}

ClientKey不仅没有值，而且您还冒着冒JSON有效性的危险，因为没有将键和值放在双引号("")内。

您的键确定，但是string值必须用双引号引起来。查看JSON网站，查看允许和禁止的内容。
