In c# you can read data from webpages by HttpWebRequest. See code below:

string html = string.Empty;
string url = @"https://www.sololearn.com";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.AutomaticDecompression = DecompressionMethods.GZip;

using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
using (Stream stream = response.GetResponseStream())
using (StreamReader reader = new StreamReader(stream))
{
html = reader.ReadToEnd();
}

Console.WriteLine(html);
