Google Search Engine Tool

Hi!
I need a internet (google) search tool that provides a list of URL´s based on multiple keywords - up to 50! A friend of mine already sent me a script, but I am not able to use it. Please have a look and send me your proposal. Thanks! Here the script I have:

using System;

using System.Collections.Generic;

using System.Net;

using HtmlAgilityPack;

namespace SearchUrl

{

class Program

{

static void Main(string[] args)

{

Console.WriteLine("Enter keywords!");

string KeyWord = Console.ReadLine();

List results = new List 0)

{

hrefValue = hrefValue.Substring(0, index);

results.Add(hrefValue.Replace("/url?q=", ""));

}

}

}

foreach (string r in results)

{

Console.WriteLine($"Result link: {r}");

}

Console.ReadLine();

}

}

}

Hope this can help!
