.NET數據合同

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

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

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

     [DataMember(Name = "nodescount")] 
     public long Nodescount { get; set; } 

     [DataMember(Name = "nodes")] 
     public IEnumerable<Node> Nodes { get; set; } 
    } 

WCF其餘呼叫

 [WebGet(UriTemplate = "/abc/nodes", 
    RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, 
    BodyStyle = WebMessageBodyStyle.Wrapped)] 
    void GetNodeTree(, 
    [MessageParameter(Name = "allnodes")] 
    out Node[] items);
