有没有一种方法可以用属性控制JsonResult的JSON输出，类似于使用XmlElementAttribute及其brethern来控制XML序列化的输出？
例如，给定以下类:
public class Foo
{
[SomeJsonSerializationAttribute("bar")]
public String Bar { get; set; }
[SomeJsonSerializationAttribute("oygevalt")]
public String Oygevalt { get; set; }
}
然后我想得到以下输出:
{ bar: '', oygevalt: '' }
As opposed to:
{ Bar: '', Oygevalt: '' }
I wanted something a bit more baked into the framework than what Jarrett suggested, so here's what I did:
JsonDataContractActionResult:
public class JsonDataContractActionResult : ActionResult
{
public JsonDataContractActionResult(Object data)
{
this.Data = data;
}
public Object Data { get; private set; }
public override void ExecuteResult(ControllerContext context)
{
var serializer = new DataContractJsonSerializer(this.Data.GetType());
String output = String.Empty;
using (var ms = new MemoryStream())
{
serializer.WriteObject(ms, this.Data);
output = Encoding.Default.GetString(ms.ToArray());
}
context.HttpContext.Response.ContentType = "application/json";
context.HttpContext.Response.Write(output);
}
}
JsonContract() method, added to my base controller class:个
public ActionResult JsonContract(Object data)
{
return new JsonDataContractActionResult(data);
}
Sample Usage:个
public ActionResult Update(String id, [Bind(Exclude="Id")] Advertiser advertiser)
{
Int32 advertiserId;
if (Int32.TryParse(id, out advertiserId))
{
// update
}
else
{
// insert
}
return JsonContract(advertiser);
}
Note:如果您正在寻找比JsonDataContractSerializer性能更好的东西，那么可以使用JSON做同样的事情.而不是网.而JSON.NET似乎没有利用DataMemberAttribute，它有自己的JsonPropertyAttribute，可以用来完成同样的事情.
