c# - 错误反序列化类型的对象......预期来自命名空间 '......' 的结束元素 ''。从命名空间 'item' 找到元素 ''

Question

当我反序列化我的 jsonstring 时，我收到错误消息

 There was an error deserializing the object of type RecordInfo. End element 'Warning' from namespace '' expected. Found element 'item' from namespace ''.

这是我的 JsonString

public const string jsonString = @" 
        {
            ""RequestId"":514106,
            ""Warning"":[],
            ""CustomerData"": {
                ""Email"":""abc@abc.com"",
                ""FullName"":""OrTguOfE"",
                ""OrderData"":[]
            }
        }";

数据契约

[DataContract]
    public class RecordInfo
    {
        [DataMember(Name = "RequestId")]
        public string RequestId { get; set; }

        [DataMember(Name = "Warning")]
        public string Warning { get; set; }

        [DataMember(Name = "CustomerData")]
        public CustomerData CustomerData { get; set; }
    }
 [DataContract]
    public class CustomerData
    {
        [DataMember(Name = "Email")]
        public string RequestId { get; set; }

        [DataMember(Name = "FullName")]
        public string FullName  { get; set; }

        [DataMember(Name = "OrderData")]
        public OrderData[]  OrderData { get; set; }
    }
[DataContract]
    public class OrderData
    {
        [DataMember(Name = "OrderId")]
        public string OrderId { get; set; }

        [DataMember(Name = "SourceId")]
        public string SourceId { get; set; }

        [DataMember(Name = "SourceData")]
        public SourceData[] SourceData { get; set; }
    }

    [DataContract]
    public class SourceData
    {
        [DataMember(Name = "SourceDescription")]
        public string SourceDescription { get; set; }

        [DataMember(Name = "ProductName")]
        public string ProductName { get; set; }
    }
}

这是我用的解串器

private static T Deserialize<T>(string jsonString)
    {
        using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(jsonString)))
        {
            var serializer = new DataContractJsonSerializer(typeof(T));
            return (T)serializer.ReadObject(ms);
        }
    }

当我反序列化上面的 jsonstring 时，我收到错误消息

 There was an error deserializing the object of type RecordInfo. End element 'Warning' from namespace '' expected. Found element 'item' from namespace ''.

有什么解决这个错误的建议吗？

设置IsRequired = false，例如:

[DataMember(Name = "RequestId", IsRequired = false)]

MSDN 来源:DataMemberAttribute.IsRequired Property

Gets or sets a value that instructs the serialization engine that the member must be present when reading or deserializing.
