c# HttpWebRequest "POST" with Loop

I wanted do POST a WebRequest for a Browser game in a loop because the POST content contains a number. Now I have a frozen program.

Here is my Code:

String loginData = "login";

// Set Cookie 
CookieContainer cookieContainer = new CookieContainer();

// Login

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("URL");
req.CookieContainer = cookieContainer;
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] loginDataBytes = encoding.GetBytes(loginData);
req.ContentLength = loginDataBytes.Length;
Stream stream = req.GetRequestStream();
stream.Write(loginDataBytes, 0, loginDataBytes.Length);
stream.Close();
HttpWebResponse res = (HttpWebResponse)req.GetResponse();

// Start the Loop

for (int i=1; i < 10; i++)
{

    String Friendly = "frday=" + i;

    req = (HttpWebRequest)HttpWebRequest.Create("URL");
    req.CookieContainer = cookieContainer;
    req.Method = "POST";
    req.ContentType = "application/x-www-form-urlencoded";
    byte[] Fr = encoding.GetBytes(Friendly);
    req.ContentLength = Fr.Length;

    Stream stream = req.GetRequestStream();
    stream.Write(Fr, 0, Fr.Length);
    stream.Close();

    Console.WriteLine("FriendlyNr: " + i);
}

The Ouput is:

FriendlyNr: 1

And the Browsergame got only the one Post Content.

So the first run is working but the second rund did not work. The Programm freezes at 

Stream stream = req.GetRequestStream();

I want to loop 10 times. How to achieve that?

You are using the same Stream object - you need to use a new HttpRequest each time. Take a look here to see a potential solution. Make sure you are also closing the Stream object as well.

Additionally, putting the code in a using statement such as using (var requestStream = request.GetRequestStream()) will help make sure that the object is disposed of and collected appropriately.
