写了两个测试了一下,自己看看吧
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");
do
{
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();
}
}
}
下面是结果

两者只相差头信息而已,速度体会不出多大的差别
