Asp.net DataContract名称属性不适用于Json序列化程序

我正在构建一个只支持JSON的WepApi，我有一个返回列表的控制器。 我用Datacontract/Datamember属性修饰了列表，如下所示：

[DataContract(Name = "Files", Namespace = "http://schemas.example.com")]
    public class FileDesc
    {
       [DataMember(Name = "MyFileName")]
       public string Name { get; set; }
       [DataMember(Name = "MyFilePath")]
       public string Path { get; set; }
       [DataMember(Name = "MyFileSize")]
       public long? Size { get; set; }
       public FileDesc(string n, string p, long? s)
       {
           Name = n;
           Path = p;
           Size = s;
       }
   }

// Response
List<FileDesc> FileList  = new List<FileDesc>();
foreach (MultipartFileData file in provider.FileData)
{
  FileList.Add(new FileDesc(file.Headers.ContentDisposition.FileName, file.LocalFileName , file.Headers.ContentDisposition.Size ));
}
return FileList;

public class Response
{
    [DataMember(Name = "Files")]
    List<FileDesc> FileList { get; set; }
}

{
    "Files": 
    [
        {
            "myFileName": "\"ArduinoUNO.png\"",
            "myFilePath": "c:\\images\\ArduinoUNO.png",
            "myFileSize": null
        }
    ]
}

在我的控制器中，我返回如下列表：

[DataContract(Name = "Files", Namespace = "http://schemas.example.com")]
    public class FileDesc
    {
       [DataMember(Name = "MyFileName")]
       public string Name { get; set; }
       [DataMember(Name = "MyFilePath")]
       public string Path { get; set; }
       [DataMember(Name = "MyFileSize")]
       public long? Size { get; set; }
       public FileDesc(string n, string p, long? s)
       {
           Name = n;
           Path = p;
           Size = s;
       }
   }

// Response
List<FileDesc> FileList  = new List<FileDesc>();
foreach (MultipartFileData file in provider.FileData)
{
  FileList.Add(new FileDesc(file.Headers.ContentDisposition.FileName, file.LocalFileName , file.Headers.ContentDisposition.Size ));
}
return FileList;

public class Response
{
    [DataMember(Name = "Files")]
    List<FileDesc> FileList { get; set; }
}

{
    "Files": 
    [
        {
            "myFileName": "\"ArduinoUNO.png\"",
            "myFilePath": "c:\\images\\ArduinoUNO.png",
            "myFileSize": null
        }
    ]
}

要强制仅输出JSON，我已删除Global.asax上的xml格式化程序：

//Only JSON
var formatters = GlobalConfiguration.Configuration.Formatters;
formatters.Remove(formatters.XmlFormatter);

提前感谢

数组本身在JSON中没有名称。如果希望列表中有名称，则需要具有命名属性的外部对象来保存列表

大概是这样的：

[DataContract(Name = "Files", Namespace = "http://schemas.example.com")]
    public class FileDesc
    {
       [DataMember(Name = "MyFileName")]
       public string Name { get; set; }
       [DataMember(Name = "MyFilePath")]
       public string Path { get; set; }
       [DataMember(Name = "MyFileSize")]
       public long? Size { get; set; }
       public FileDesc(string n, string p, long? s)
       {
           Name = n;
           Path = p;
           Size = s;
       }
   }

// Response
List<FileDesc> FileList  = new List<FileDesc>();
foreach (MultipartFileData file in provider.FileData)
{
  FileList.Add(new FileDesc(file.Headers.ContentDisposition.FileName, file.LocalFileName , file.Headers.ContentDisposition.Size ));
}
return FileList;

public class Response
{
    [DataMember(Name = "Files")]
    List<FileDesc> FileList { get; set; }
}

{
    "Files": 
    [
        {
            "myFileName": "\"ArduinoUNO.png\"",
            "myFilePath": "c:\\images\\ArduinoUNO.png",
            "myFileSize": null
        }
    ]
}

谢谢你，这就是我要找的。我刚刚开始使用JSON。
