Wie man Stadt, Staat, Land von Google Karte Geocoding JSON Daten lesen

Question

Ich benutze .net MVC 3 und Google Maps v3. Ich möchte Geocoding in einer Aktion durchführen. Das ist eine gültige Adresse an Google und die Stadt, Staat und Land zurück zu bekommen. Wie würden Sie dies in einer Aktion mit C# tun?

[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); 
    } 

dies json Daten, die ich von Google Geocoding, von dem ich aus address_components Stadt, Staat und Land lesen, will ich immer auch Arten administrative_area_level_2, administrative_area_level_1, Land

    "results" : [

Answer 1

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); 
        } 

       } 

Answer 2

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

möglich verwendet wie folgt

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

Ergebnis ist 1. Array von JSON
