Question

我正在尝试反序列化此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：}。路径''，第1行，第19位。

我在这里做错了什么？这是我的代码，顺便说一下：

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;
        }
    }
}

修改我昨晚正在寻找示例，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，我改变了它：

[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; }

}

到此：

[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; }

}

但我必须测试它，看看它是否有效。顺便说一句，我怎么能用Fiddler测试呢？

编辑好吧，当我在Fiddler上测试时，WCF给了我另一个错误：

解析值时遇到意外的字符：d。路径''，第0行，第0位。

我检查了JSON示例。没有办法会有未知的角色。

Answer 1

在运行时没有看到内容的情况下很难分辨，但正如MaxJ提到的那样，它可能与MeetingDate中的转义字符有关，所以请尝试在“2016年2月16日”前面弹出一个@符号来否定它们。 / p>

Answer 2

为什么用你的MeetingDetailsForDeserializing属性作为前缀j？你的json字符串应该与属性匹配。我试图模仿你拥有的同样的json，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？

然而，这是我试过的测试的快照。
JS模型

＆＃13;

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"
        };

＆＃13;

[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; }
}
