How to set user agent property in WebRequest

[Hadi Hadizadeh]

Hi,

I am using the following MQL5 code to fetch data from a web service:

   string cookie=NULL,headers;
   char   post[],result[];
   string referer = NULL;
   string url="http://www.test.com";
   int res=WebRequest("GET",url,cookie,referer,500,post,0,result,headers);

However, I need to specify the user agent property in the header of the request. How can we do that? In know in C# we can do so as follows:

using System;  
using System.IO;  
using System.Net;  
using System.Text;  
  
namespace Examples.System.Net  
{  
    public class WebRequestGetExample  
    {  
        public static void Main ()  
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.test.com");
            request.UserAgent = "Mozilla / 5.0(Windows NT 10.0; Win64; x64) AppleWebKit / 537.36(KHTML, like Gecko) Chrome / 70.0.3538.77 Safari / 537.36";
            request.Headers.Add(HttpRequestHeader.Accept, "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
            request.Headers.Add(HttpRequestHeader.AcceptLanguage, "de-DE");

            using (var response = (HttpWebResponse)(request.GetResponse()))
            {
                                
            }
        }  
    }
}
