google-search-results-dotnet 1.3.0

Google/Bing/Baidu Search Result in Dotnet / CSharp / .Net

This Dotnet package is meant to scrape and parse Google or Bing or Baidu results using SerpApi.

This extension is in development. But the code can be re-use for production because the API is already stable.

The following services are provided:

• Search API
• Location API - not implemented
• Search Archive API - not implemented
• Account API - not implemented

Serp API provides a script builder to get you started quickly.

Feel free to fork this repository to add more backends.

Installation

To install the package.

dotnet add package google-search-results-dotnet --version 1.2.0

More commands available at https://www.nuget.org/packages/google-search-results-dotnet

Quick start

Let's run a search on Google.

using System;
using SerpApi;
using System.Net.Http;
using Newtonsoft.Json.Linq;
using System.Collections;
using System.Collections.Generic;
using System.Threading.Tasks;
using System.Text.RegularExpressions;

namespace Baidu
{
  class Program
  {

    static void Main(string[] args)
    {
      // secret api key from https://serpapi.com/dashboard
      String apiKey = "";

      // Localized search for Coffee shop in Austin Texas
      Hashtable ht = new Hashtable();
      ht.Add("location", "Austin, Texas, United States");
      ht.Add("q", "Coffee");
      ht.Add("hl", "en");
      ht.Add("google_domain", "google.com");

      try
      {
        BaiduSearchResultsClient client = new BaiduSearchResultsClient(ht, apiKey);

        Console.WriteLine("Search coffee in Austin, Texas on Google [1 credit]");
        JObject data = client.GetJson();
        Console.WriteLine("local coffee shop");
        JArray coffeeShops = (JArray)data["local_results"];
        foreach (JObject coffeeShop in coffeeShops)
        {
          Console.WriteLine("Found: " + coffeeShop["title"]);
        }
        Console.WriteLine("organic result coffee shop");
        coffeeShops = (JArray)data["organic_results"];
        foreach (JObject coffeeShop in coffeeShops)
        {
          Console.WriteLine("Found: " + coffeeShop["title"]);
        }

        string id = (string)((JObject)data["search_metadata"])["id"];
        Console.WriteLine("Search from the archive: " + id + ". [0 credit]");
        JObject archivedSearch = client.GetSearchArchiveJson(id);
        foreach (JObject coffeeShop in (JArray)archivedSearch["organic_results"])
        {
          Console.WriteLine("Found: " + coffeeShop["title"]);
        }

        //  Get account information
        Console.WriteLine("Account information: [0 credit]");
        JObject account = client.GetAccount();
        Dictionary<string, string> dictObj = account.ToObject<Dictionary<string, string>>();
        foreach (string key in dictObj.Keys)
        {
          Console.WriteLine(key + " = " + dictObj[key]);
        }
      }
      catch (SerpApiClientException ex)
      {
        Console.WriteLine("Exception:");
        Console.WriteLine(ex.ToString());
      }
    }
  }
}

This example displays the top 3 coffee shop in Austin Texas found in the local_results. Then it displays all 10 coffee shop found in the regular google search named: organic_results.

Bing search engine

client =  new BingSearchResultsClient(parameter, apiKey);

A full example is available here. https://github.com/serpapi/google-search-results-dotnet/blob/master/example/bing/

Baidu search engine

client =  new BaiduSearchResultsClient(parameter, apiKey);

A full example is available here. https://github.com/serpapi/google-search-results-dotnet/blob/master/example/baidu/
