Send Multiple Posts At A Time

Question

I am using a SQL Query to select data from my database and storing the returned results in a Dictionary<string, string> I then use a foreach loop and Server.UrlEncode to create a Querystring like such

foreach (var onetwo in privatedictionary) 
    dataToPost = onetwo.Key+"="+Server.UrlEncode(onetwo.Value)+"&";

then once the data has been compiled into dataToPost I use HttpWebRequest to send the data

HttpWebRequest wbrq = (HttpWebRequest)WebRequest.Create("www.sitetohit.com");
{
  using (StreamWriter sw = new StreamWriter(wbrq.GetRequestStream()))
  {
    sw.Write(dataToPost);
  }
}

What is a way using Visual Studio 2015 to send multiple Posts at once?

Answer 1

There are multiple ways, the best that I experienced are bellows:

Parallel.ForEach(privatedictionary, (dataToPost) =>
        {
            HttpWebRequest wbrq = (HttpWebRequest)WebRequest.Create("www.sitetohit.com");
            {
                using (StreamWriter sw = new StreamWriter(wbrq.GetRequestStream()))
                {
                    sw.Write(dataToPost);
                }
            }
        });

Or:

foreach (var dataToPost in privatedictionary)
        {
            Task.Run(async () =>
            {
                Foo foo = new Foo();
                await foo.BarAsync(dataToPost);
            });
        }

  //Asynchronous Handling
  public class Foo
{
    public async Task BarAsync(string dataToPost)
    {
        HttpWebRequest wbrq = (HttpWebRequest)WebRequest.Create("www.sitetohit.com");
        {
            using (StreamWriter sw = new StreamWriter(wbrq.GetRequestStream()))
            {
                await sw.WriteAsync(dataToPost);
            }
        }
    }
}

You can use this:

Parallel.ForEach(privatedictionary, (onetwo) =>
        {
            var dataToPost = onetwo.Key + "=" + Server.UrlEncode(onetwo.Value) + "&";
            HttpWebRequest wbrq = (HttpWebRequest)WebRequest.Create("www.sitetohit.com");
            {
                using (StreamWriter sw = new StreamWriter(wbrq.GetRequestStream()))
                {
                    sw.Write(dataToPost);
                }
            }
        });
