根据网上源码综合的使用代理的投票程序，几个问题解决不了，讨论下

[oneby]

程序可以运行，也可以投票。问题：在网上找的代理ip大多报错，不知是ip不能用，还是代码的问题？投票的速度很慢，不知怎么解决？欢迎讨论，争取今天解决

private void button1_Click(object sender, System.EventArgs e)
{
try
{//代理服务的ip和端口放在poll.txt文件中
StreamReader s = File.OpenText("poll.txt");
string read = null;
while((read = s.ReadLine()) != null)
{
poll(read);//读取每一行代理ip的数据，开始投票
}
s.Close();
}
catch(Exception ex)
{
MessageBox.Show(ex.Message,"Error");
}

private void poll(string p)
{
try
{
byte[]temp = Encoding.ASCII.GetBytes("此处是提交的数据");
HttpWebRequest hwr = (HttpWebRequest)WebRequest.Create("此处是数据提交的地址");
hwr.Method = "POST";
hwr.ContentType="application/x-www-form-urlencoded";
hwr.ContentLength = temp.Length;
WebProxy wp = new WebProxy(p,true);
hwr.Proxy = wp;

Stream newStream=hwr.GetRequestStream();
// Send the data.
newStream.Write(temp,0,temp.Length);
newStream.Close();
HttpWebResponse myResponse=(HttpWebResponse)hwr.GetResponse();
StreamReader reader = new StreamReader(myResponse.GetResponseStream(),Encoding.Default);
string content = reader.ReadToEnd();

if(content.IndexOf("不接受重复投票")< 0)
{
count ++;
}
}
catch(Exception ex)
