返回带有 Request.CreateResponse 的 JsonArray

我构建了一个 ASP.NET Web API。现在，我已经将项目更新为 MVC 4 RC，但动态对象不再按预期工作。

我有这个：

var Arr = new JsonArray();
foreach (var Post in Coll)
{
    dynamic Item = new JsonObject();
    Item.Header = Post.Header;
    Item.Body = Post.Body;
    Item.Language = Post.Language;
    Arr.Add(Item);
}
return Request.CreateResponse(HttpStatusCode.OK, Arr);

我从中得到的结果是（在浏览器中）：

[{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]},{"Header":[],"Body":[],"Language":[]}]

在调试中，我得到这个：（对象Arr）

{[{"Header":"All distances","Body":"All distances are ","Language":"EN"},{"Header":...

为什么不同？

（Coll 是一个对象列表）

返回带有 Request.CreateResponse 的 JsonArray

尝试使用它

return Request.CreateResponse（HttpStatusCode.OK， Arr.ToArray（））;

这只是一个猜测，如果您可以在调试中看到它，那么当您添加到监视列表并且观察程序显示它时，您可能强制计算对象。然后。ToArray（） 也应该对你有所帮助。

我想你没有在客户端将 Arr 解析为 json 数据。在客户端 AJAX 方法中尝试此操作：

 var obj = $.parseJSON(result);

结果是从服务器返回的值。您可以获取数组的每个对象，如下所示：

        $(obj).each(function () {       
      // alert($(this).attr('Header'));  
 });

遇到了同样的问题，我已经修复了它，以这种方式插入内容：

var response = req.CreateResponse(HttpStatusCode.OK);
response.Content = new StringContent(JsonConvert.SerializeObject(MY_OBJECT, Formatting.Indented), Encoding.UTF8, "application/json");
return response;
