Вы можете создать класс здесь http://json2csharp.com/, это очень легко.

Учитывая, что вы успешно загрузили строку json, вот код в качестве консольного приложения. Он использует json.net (https://www.nuget.org/packages/Newtonsoft.Json/7.0.1-beta2)

class Program 
    { 
     static void Main(string[] args) 
     { 
      var json = @".... json string...."; 
      var obj = JsonConvert.DeserializeObject<RootObject>(json); 
      Console.WriteLine(obj.responseData.cursor.estimatedResultCount) 
       ; 
      Console.ReadLine(); 
     } 
    } 
    public class Result 
    { 
     public string GsearchResultClass { get; set; } 
     public string unescapedUrl { get; set; } 
     public string url { get; set; } 
     public string visibleUrl { get; set; } 
     public string cacheUrl { get; set; } 
     public string title { get; set; } 
     public string titleNoFormatting { get; set; } 
     public string content { get; set; } 
    } 
    public class Page 
    { 
     public string start { get; set; } 
     public int label { get; set; } 
    } 
    public class Cursor 
    { 
     public string resultCount { get; set; } 
     public List<Page> pages { get; set; } 
     public string estimatedResultCount { get; set; } 
     public int currentPageIndex { get; set; } 
     public string moreResultsUrl { get; set; } 
     public string searchResultTime { get; set; } 
    } 
    public class ResponseData 
    { 
     public List<Result> results { get; set; } 
     public Cursor cursor { get; set; } 
    } 
    public class RootObject 
    { 
     public ResponseData responseData { get; set; } 
     public object responseDetails { get; set; } 
     public int responseStatus { get; set; } 
    }
