使用 JSON.Net 反序列化 JSON 对象

Question

我正在尝试反序列化这个 JSON 对象，然后将其插入数据库：

{
    "PresiderEmailAddress": "kyitss@gmail.com",
    "MeetingNumber": "ME021616",
    "MeetingName": " Quotation Meeting",
    "MeetingDescription": "NULL",
    "MeetingDate": "2\/16\/2016",
    "MeetingVenue": "Consular Room",
    "TimeStarted": "12:00:00",
    "TimeEnded": "13:00:00",
    "CompletionRate": 0.0,
    "Remarks": "Actions still in progress"
}

但是我的 WCF 服务总是给我这个错误

无效的 JavaScript 属性标识符字符：}。路径 ''，第 1 行，位置 19。

我在这里做错了什么？这是我的代码，顺便说一句：

public Int32 InsertMeeting(string jsonMeetingDetails)
{
    MeetingDetailsForDeserializing obj = JsonConvert.DeserializeObject<MeetingDetailsForDeserializing>(jsonMeetingDetails);

    using (SqlConnection connection = new SqlConnection(constring))
    {
        Int32 insertResult;
        SqlCommand cmd = new SqlCommand("Insert into dbo.Meeting(MeetingNumber, PresiderEmailAddress, MeetingName, MeetingDescription, MeetingDate, MeetingVenue, TimeStarted, TimeEnded,CompletionRate, Remarks) values(@MeetingNumber, @PresiderEmailAddress,@MeetingName, @MeetingDescription, @MeetingDate, @MeetingVenue, @TimeStarted, @TimeEnded, @CompletionRate, @Remarks)");
        cmd.CommandType = CommandType.Text;
        cmd.Connection = connection;
        cmd.Parameters.AddWithValue("@MeetingNumber", obj.jMeetingNumber);
        cmd.Parameters.AddWithValue("@PresiderEmailAddress", obj.jPresiderEmailAddress);
        cmd.Parameters.AddWithValue("@MeetingName", obj.jMeetingName);
        cmd.Parameters.AddWithValue("@MeetingDescription", obj.jMeetingDescription);
        cmd.Parameters.AddWithValue("@MeetingDate", obj.jMeetingDate);
        cmd.Parameters.AddWithValue("@MeetingVenue", obj.jMeetingVenue);
        cmd.Parameters.AddWithValue("@TimeStarted", obj.jTimeStarted);
        cmd.Parameters.AddWithValue("@TimeEnded", obj.jTimeEnded);
        cmd.Parameters.AddWithValue("@CompletionRate", obj.jCompletionRate);
        cmd.Parameters.AddWithValue("@Remarks", obj.jRemarks);

        connection.Open();
        insertResult = cmd.ExecuteNonQuery();
        connection.Close();

        if (insertResult == 1)
        {
            return 1;
        }
        else 
        {
            return 0;
        }
    }
}

编辑 我昨晚在寻找示例，似乎我用来反序列化对象的类与 JSON 不匹配。而且根据下面的帖子，我把它改成了这样：

[DataContract]
public class MeetingDetailsForDeserializing
{
    [DataMember(Order = 0)]
    public string jPresiderEmailAddress { get; set; }

    [DataMember(Order = 1)]
    public string jMeetingNumber { get; set; }

    [DataMember(Order = 2)]
    public string jMeetingName { get; set; }

    [DataMember(Order = 3)]
    public string jMeetingDescription { get; set; }

    [DataMember(Order = 4)]
    public string jMeetingDate { get; set; }

    [DataMember(Order = 5)]
    public string jMeetingVenue { get; set; }

    [DataMember(Order = 6)]
    public string jTimeStarted { get; set; }

    [DataMember(Order = 7)]
    public string jTimeEnded { get; set; }

    [DataMember(Order = 8)]
    public decimal jCompletionRate { get; set; }

    [DataMember(Order = 9)]
    public string jRemarks { get; set; }

}

对此：

[DataContract]
public class MeetingDetailsForDeserializing
{
    [DataMember(Order = 0)]
    public string PresiderEmailAddress { get; set; }

    [DataMember(Order = 1)]
    public string MeetingNumber { get; set; }

    [DataMember(Order = 2)]
    public string MeetingName { get; set; }

    [DataMember(Order = 3)]
    public string MeetingDescription { get; set; }

    [DataMember(Order = 4)]
    public string MeetingDate { get; set; }

    [DataMember(Order = 5)]
    public string MeetingVenue { get; set; }

    [DataMember(Order = 6)]
    public string TimeStarted { get; set; }

    [DataMember(Order = 7)]
    public string TimeEnded { get; set; }

    [DataMember(Order = 8)]
    public decimal CompletionRate { get; set; }

    [DataMember(Order = 9)]
    public string Remarks { get; set; }

}

但我仍然必须对其进行测试，看看它是否有效。顺便说一句，我如何使用 Fiddler 进行测试？

编辑好吧，当我在 Fiddler 上测试时，WCF 又给了我一个错误：

解析值时遇到意外字符：d。路径''，第 0 行，第 0 位置。

我检查了 JSON 示例。不可能有未知字符。

Answer 1

在运行时不看内容很难判断，但正如 MaxJ 所说，这可能与 MeetingDate 中的转义字符有关，因此请尝试在“2/16/2016”前面弹出一个@符号来否定它们。

Answer 2

为什么在 j 前面加上 MeetingDetailsForDeserializing 的属性？您的 json 字符串应与属性匹配。我试图模仿你所拥有的相同的 json，并且我能够成功地反序列化它。最初我期待日期错误，但这并没有发生。你能展示一下 MeetingDetailsForDeserializing 类吗？

但是，这是我尝试过的测试的快照。
JS 模型

var data1 = {
            "PresiderEmailAddress": "kyitss@gmail.com",
            "MeetingNumber": "ME021616",
            "MeetingName": " Quotation Meeting",
            "MeetingDescription": "NULL",
            "MeetingDate": "2\/16\/2016",
            "MeetingVenue": "Consular Room",
            "TimeStarted": "12:00:00",
            "TimeEnded": "13:00:00",
            "CompletionRate": 0.0,
            "Remarks": "Actions still in progress"
        };

[这是c#模型类]

 [DataContract]
public class MeetingDetailsForDeserializing
{
    [DataMember(Order = 0)]
    public string MeetingNumber { get; set; }
    [DataMember(Order = 1)]
    public string PresiderEmailAddress { get; set; }
    [DataMember(Order = 2)]
    public string MeetingName { get; set; }
    [DataMember(Order = 3)]
    public string MeetingDescription { get; set; }
    [DataMember(Order = 4)]
    public DateTime MeetingDate { get; set; }
    [DataMember(Order = 5)]
    public string MeetingVenue { get; set; }
    [DataMember(Order = 6)]
    public string TimeStarted { get; set; }
    [DataMember(Order = 7)]
    public string TimeEnded { get; set; }
    [DataMember(Order = 8)]
    public string CompletionRate { get; set; }
    [DataMember(Order = 9)]
    public string Remarks { get; set; }
}

如果我遗漏了什么，请告诉我。
