内存不足$_GET

我正在创建一个多线程的random.org数字getter来实现我的c# IRC bot。我的问题是，它占用了相当大的内存。我想是WebClient课。我不喜欢它如何使用~5,000K内存只是为了连接到url，并读取第一行并输出数字。

有更轻松的方法吗?

class Program
    {
        static void Main(string[] args)
        {
            for (int i = 0; i < 4; i++)
            {
                Thread More = new Thread(GetRandomNum);
                More.Start();
            }
        }
        public static void GetRandomNum()
        {
            string number;
            for (int i = 0; i < 100; i++)
            {
                using (WebClient client = new WebClient())
                {
                    number = client.DownloadString("http://www.random.org/integers/?num=1&min=1&max=100&col=1&base=10&format=plain&rnd=new");
                }
                Console.WriteLine(number.Trim());
            }
        }
    }

WebRequest request = WebRequest.Create ("http://www.random.org/integers/?num=1&min=1&max=100&col=1&base=10&format=plain&rnd=new");
// If required by the server, set the credentials.
// Get the response.
HttpWebResponse response = (HttpWebResponse)request.GetResponse ();
// Display the status.
// Get the stream containing content returned by the server.
Stream dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Cleanup the streams and the response.
reader.Close ();
dataStream.Close ();
response.Close ();
