C# 如何从谷歌地图地理编码json数据中读取城市、州、国家

我正在使用.NETMVC3和谷歌地图v3。我想在action中进行地理编码。这就是将一个有效地址传递给谷歌，并获取城市、州和国家的信息。在使用C的操作中，您将如何做到这一点

    [HttpPost]
    public ActionResult getLocation(string pincode)
    {
        string url = "http://maps.googleapis.com/maps/api/geocode/json?
         sensor=true&address=";
        var data="";
        dynamic googleResults = new Uri(url + 
         pincode).GetDynamicJsonObject();
        foreach (var result in googleResults.results)
        {

            data= "[" + result.geometry.location.lat + "," + 
         result.geometry.location.lng + "] " + result.formatted_address;
        }
        return Json("Successful" + data, JsonRequestBehavior.AllowGet);
    }

这是我从谷歌地理编码中获得的json数据，我想从地址、组件类型、行政区、级别、国家/地区中读取城市、州和国家/地区

         "types" : [ "postal_code" ]
      }
   ],
   "status" : "OK"
}

你也可以这样使用

data=["result"]["address_components"]["type"]["administrative_level_2"][your value];
data2=["result"]["address_components"]["type"]["administrative_level_1"][your value];

结果是json的第一个数组

如果只设置了一个单一的数据变量，为什么要使用foreach？为什么要在这个字符串前面加上返回JsonSuccessful+数据的前缀，这可能会创建无效的结果？因为我希望在ajax成功方法中返回此数据，为什么不只返回JsongoogleResults、JsonRequestBehavior.AllowGet；？然后你可以得到JSON字符串并在客户端处理它。是的，我也可以这样做，但无论我是在服务器端处理数据然后发送，还是先在客户端发送数据然后处理，都是一样的。我的问题是如何读城市，州和国家分开，而不是读格式化的地址谢谢@Mark Schultheis的建议

I solved this problem by sending json data to client side like this
 var data = "";
            dynamic googleResults = new Uri(url + pincode).GetDynamicJsonObject();
            var status = googleResults.status;
            foreach (var result in googleResults.results)
            {
                              data += result;
            }
            return Json(data, "application/json",Encoding.UTF8, JsonRequestBehavior.AllowGet);


and then process this data in javascript ,code given below

 data = JSON.parse(result);

                for(var i=0;i<data.address_components.length;i++)
                {

                    if(data.address_components[i].types[0]=="administrative_area_level_2")
                    {
                        alert("City:" + data.address_components[i].long_name);
                        document.getElementById("pin_city").value = data.address_components[i].long_name;
                    }
                    if (data.address_components[i].types[0] == "administrative_area_level_1") {
                        alert("State:" + data.address_components[i].long_name);
                        document.getElementById("pin_state").value = data.address_components[i].long_name;
                    }
                    if (data.address_components[i].types[0] == "country") {
                        alert("Country:" + data.address_components[i].long_name);
                    }
