Two ways to send an HTTP request

The request has written two Tests.

public void GetResponse ()
{
StringBuilder strsource = new StringBuilder ();
Try
{
WebRequest wreq = WebRequest.Create ("http://www.dev-club.com");
WebResponse wresp = Wreq.getresponse ();

Uri Myuri = new Uri (this.l_strpageaddress);
HttpWebResponse resp;
HttpWebRequest req =
(HttpWebRequest) WebRequest.Create (Myuri);
RESP = (HttpWebResponse) req. GetResponse ();


StreamReader sr = new StreamReader (resp. GetResponseStream (), encoding.default);
String strtemp = "";

while (strtemp = Sr. ReadLine ())!= null)
{
Strsource.append (strtemp + "\ r \ n");
}

Sr. Close ();
}
catch (WebException WEBEXCP)
{
Strsource.append (Webexcp.message);
}
This.form.AddMessage (Strsource.tostring ());
}

public void Socket_getresponse ()
{


Iphostentry ipinfo = Dns.resolve (l_strserveraddress);
IPAddress IP = ipinfo. ADDRESSLIST[0];
IPEndPoint rip = new IPEndPoint (ip,80);

s = new Socket (ADDRESSFAMILY.INTERNETWORK,SOCKETTYPE.STREAM,PROTOCOLTYPE.TCP);

Try
{

This.form.AddMessage ("Connecting to" +ip. ToString ());

S.connect (RIP);

int bytesrecv = 0;
String output = "";
String temp = "";
byte[] bytes;

This.form.AddMessage ("Sending request to" +l_strpageaddress);

String Command = "Post" +l_strpageaddress+ "http/1.0\r\n";
Command + + "accept:*/*\r\n";
Command + + "accept:text/html\r\n";
Command + = "\ r \ n";

byte[] msg = Encoding.Default.GetBytes (Command);


int intsend = S.send (msg,msg. length,0);

This.form.AddMessage ("Sent" +intsend.tostring () + "bytes to server");

Todo
{
bytes = new byte[1024];
BYTESRECV = S.receive (bytes,bytes. Length,socketflags.none);
temp = Encoding.Default.GetString (BYTES,0,BYTESRECV);
This.form.AddMessage (temp);
output = temp;
}
while (bytesrecv>0);

This.form.AddMessage (output);
}
catch (Exception e)
{
This.form.AddMessage (E.message);
}
Finally
{
if (s!= null & s.connected)
{
S.shutdown (Socketshutdown.both);
S.close ();
}
}

}

Here's the result.

The difference between the two is only the first information, speed does not realize how much different
