Mvc4 WebApi 返回 格式

一般 WebApi 是根据客户端请求 类型进行对应的返回格式

    function getAll() {
        $.ajax({
            url: "http://localhost:37980/api/Test/Show/3",
            type: 'GET',
            dataType: "json",
            success: function (data) {
                var s = "";
                $.each(data, function (i, val) {
                    s += val.Name;
                });

                $("#modes").html(s);

            }
        }).fail(
             function (xhr, textStatus, err) {
                 alert('Error: ' + err);
             });
    }

就会返回 json格式

如果想固定请求成json格式

在TestController.cs

         [HttpGet]
        public HttpResponseMessage Show(int id)
        {
            Test p = TestBLL.GeTest(id);
          
            return ToJson(JsonConvert.SerializeObject(p));
           

        }

         private HttpResponseMessage ToJson(string jsonData)
        {
            HttpResponseMessage result = new HttpResponseMessage
            {
                Content = new StringContent(jsonData, Encoding.GetEncoding("UTF-8"), "application/json")
            };
            return result;

        }
