how to make google map coordinates request more precise/accurate with c# winform?

Question

Im building a winform project using Google maps api. im sending an address and i get the address coordinates as a result. However, im not getting the most accurate results... here is my code:

using System.Net;
using System.Runtime.Serialization.Json;

namespace WinForm_Project
{
   class GoogleMaps
   {
       public static GeoResponse GetGeoCodedResults(string address) and uses google maps to retrieve the address's coordinates. 
       {
           string url = string.Format("http://maps.google.com/maps/api/geocode/json?address={0}&region=dk&sensor=false",HttpUtility.UrlEncode(address));
           var request = (HttpWebRequest)HttpWebRequest.Create(url);
           request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip,deflate");
           request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
           DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(GeoResponse));
           var res = (GeoResponse)serializer.ReadObject(request.GetResponse().GetResponseStream());
           return res;
       }
   }
}

this part works just fine. (just to be clear - my winform app does not contain a google map) i noticed when i type an address on google maps's website i get certain coordinates - but the coordinates (Latitude, longitude) become more accurate when i zoom-in...

is there a way to change the request\\code to get from google a more accurate results? such as Max zoom-in will display on google maps.

Thanks

Using Google's JSON option, your result will contain something like this.

...
"geometry" : {
        "bounds" : {
           "northeast" : {
              "lat" : 40.91525559999999,
              "lng" : -73.70027209999999
           },
           "southwest" : {
              "lat" : 40.495908,
              "lng" : -74.2590879
           }
        },
        "location" : {
           "lat" : 40.7143528,
           "lng" : -74.00597309999999
...

The exact 'point' will be under results-->geometry-->location. However, if your query is an area, say New York City, then you will get a bounding box for that area (results-->geometry-->bounds). If that's the case, the exact location given would probably be the center of that area or a commonly accepted point.
