Asp.net mvc GeoJSON.NET与ASP.NET MVC中的谷歌地图

我正在尝试使用ASP.NET MVC5库创建geoJSON数据并将其加载到Google地图中，尽管我在某些地方做了一些错误的事情

使用GitHub站点上发布的示例代码，我的控制器如下所示：

public ActionResult GetGeoJson()
{
    var point = new GeoJSON.Net.Geometry.Point(
                    new GeoJSON.Net.Geometry.GeographicPosition(45.79012, 15.94107));
    var featureProperties = new Dictionary<string, object> { {"Name", "Foo"} };
    var model = new GeoJSON.Net.Feature.Feature(point, featureProperties);
    var serializedData = JsonConvert.SerializeObject(model, Formatting.Indented,
               new JsonSerializerSettings
               {
                   ContractResolver = new CamelCasePropertyNamesContractResolver(),
                   NullValueHandling = NullValueHandling.Ignore 
               });

    return Json(serializedData, JsonRequestBehavior.AllowGet);
}

一位亲戚给了我答案。我需要从更改控制器中的返回

return Json(serializedData, JsonRequestBehavior.AllowGet);

到

因为JsonResult也在序列化序列化的数据

"{\r\n  \"geometry\":
{\r\n    \"coordinates\": [\r\n      15.94107,\r\n      45.79012\r\n    ],
\r\n    \"type\": \"Point\"\r\n  },
\r\n  \"properties\": {\r\n    \"name\": \"Foo\"\r\n  },
\r\n  \"type\": \"Feature\"\r\n}"

return Json(serializedData, JsonRequestBehavior.AllowGet);

return Content(serializedData, "application/json");
