如何從WCF服務返回干凈的JSON？我正在嘗試從WCF服務返回一些JSON。這個服務只是從我的數據庫中返回一些內容。我可以得到數據。但是，我擔心JSON的格式。當前，返回的JSON格式如下：{"d":"[{\"Age\":35,\"FirstName\":\"Peyton\",\"LastName\":\"Manning\"},{\"Age\":31,\"FirstName\":\"Drew\",\"LastName\":\"Brees\"},{\"Age\":29,\"FirstName\":\"Tony\",\"LastName\":\"Romo\"}]"}實際上，我希望我的JSON格式盡可能清晰。我認為(我可能不正確)，相同的結果集合(用干凈的JSON表示)應該如下所示：[{"Age":35,"FirstName":"Peyton","LastName":"Manning"},{"Age":31,"FirstName":"Drew","LastName":"Brees"},{"Age":29,"FirstName":"Tony","LastName":"Romo"}]我不知道“d”是從哪里來的。我也不知道為什么要插入轉義字符。我的實體看起來如下：[DataContract]public class Person{
[DataMember]
public string FirstName { get; set; }
[DataMember]
public string LastName { get; set; }
[DataMember]
public int Age { get; set; }
public Person(string firstName, string lastName, int age)
{
this.FirstName = firstName;
this.LastName = lastName;
this.Age = age;
}}負責返回內容的服務定義為：[ServiceContract(Namespace = "")][AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]public class TestService{
[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json)]
public string GetResults()
{
List<Person> results = new List<Person>();
results.Add(new Person("Peyton", "Manning", 35));
results.Add(new Person("Drew", "Brees", 31));
results.Add(new Person("Tony", "Romo", 29));
// Serialize the results as JSON
DataContractJsonSerializer serializer = new DataContractJsonSerializer(results.GetType());
MemoryStream memoryStream = new MemoryStream();
serializer.WriteObject(memoryStream, results);
// Return the results serialized as JSON
string json = Encoding.Default.GetString(memoryStream.ToArray());
return json;
}}如何從WCF服務返回“干凈”JSON？謝謝!

List<Person>.
public List<Person> GetPlayers(){
List<Person> players = new List<Person>();
players.Add(new Person { FirstName="Peyton", LastName="Manning", Age=35 } );
players.Add(new Person { FirstName="Drew", LastName="Brees", Age=31 } );
players.Add(new Person { FirstName="Brett", LastName="Favre", Age=58 } );
return players;}[{"Age":35,"FirstName":"Peyton","LastName":"Manning"},
{"Age":31,"FirstName":"Drew","LastName":"Brees"},
{"Age":58,"FirstName":"Brett","LastName":"Favre"}][WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "players")]
