Get Google query Json with Webbrowser C#

Question

I need to perform the following process, perform a google search and get the search information in Json format, how could I do this?

I tried to do it this way, I used Webbrowser from C# and I navigated the site www.google.com, until then it worked out, only I need to get this information as Title and Link of the results of this search, someone knows the best way to do it?

NOTE: I can’t use the google API, I need to do it by hand.

    private void btnPesquisar_Click(object sender, EventArgs e)
    {
        webBrowser.Navigate("www.google.com/search?q=" + txtPesquisa.Text);

        var document = webBrowser.Document;
    }

Answer 1

We all know that the result of webbrowser will be an HTML, so let’s go through the html getting the elements that are needed, the Divs, in the case of google, that have class 'g' indicating that it is a result of the search.

After having this element, just take the link, indicated by the tag and then we can get its properties.

Follows code:

Click:
webBrowser1.Navigate("https://www.google.com/search?num=100&q=carros");

Tip: Use the num parameter to get more results: search?num=100&q=[your search]

 private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        HtmlElementCollection divs = webBrowser1.Document.GetElementsByTagName("div");
        List<Resultados> resultados = new List<Resultados>();
        Resultados r;
        foreach (HtmlElement x in divs)
        {
            if (x.GetAttribute("className") == "g")
            {
                HtmlElement link = x.GetElementsByTagName("a")[0];
                r = new Resultados();
                r.Titulo = link.InnerText;
                r.Url = link.GetAttribute("href");
                resultados.Add(r);
            } 
        }

        int cout = resultados.Count; //Sua List com todos os resultados da pesquisa.

    }

    public class Resultados
    {
        public string Url { get; set; }
        public string Titulo { get; set; }
    }

Now json: I used the library Newtonsoft.Json

string json = "";
foreach (Resultado r in resultados)
    json+=  Newtonsoft.Json.JsonConvert.SerializeObject(r);


string seuJsonCompleto = json;
