我正在做 JSON 解析，我有以下结果；

我必须实现的是以下 JSON 格式：

    }
]
}

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”；

有谁知道我应该怎么做？

您可以使用Order属性的[DataMember]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; }
}
