这是我在WCF服务中返回JSON的方法。
[OperationContract]
[WebInvoke(Method = "GET",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "json")]
Container GetClinicInfo();
[DataContract]
public class Container
{
[DataMember]
public string displayFieldName { get; set; }
[DataMember]
public FieldAliases alias { get; set; }
[DataMember]
public string geometryType { get; set; }
[DataMember]
public SpatialReference wkids { get; set; }
[DataMember]
public fieldContainer field { get; set; }
[DataMember]
public Features feature { get; set; }
[DataContract]
public class Container
{
[DataMember]
public string displayFieldName { get; set; }
[DataMember]
public FieldAliases alias { get; set; }
[DataMember]
public string geometryType { get; set; }
[DataMember]
public SpatialReference wkids { get; set; }
[DataMember]
public fieldContainer field { get; set; }
[DataMember]
public Features feature { get; set; }
public Container(string display,FieldAliases aliases,string type,SpatialReference spatial,fieldContainer container, Features fea)
{
displayFieldName = display;
alias = aliases;
geometryType = type;
wkids = spatial;
field = container;
feature = fea;
}
现在，JSON正在按字母顺序解析"Container";

有人知道我应该怎么做吗?
您可以使用[DataMember]属性的Order属性来定义字段序列化的顺序:
[DataContract]
public class Container
{
[DataMember(Order = 1)]
public string displayFieldName { get; set; }
[DataMember(Order = 2)]
public FieldAliases fieldAliases { get; set; }
[DataMember(Order = 3)]
public string geometryType { get; set; }
[DataMember(Order = 4)]
public SpatialReference spatialReference { get; set; }
[DataMember(Order = 5)]
public fieldContainer fields { get; set; }
[DataMember(Order = 6)]
public Features features { get; set; }
}
