我在调用多个URI时遇到问题，目前它的工作方式是当前形式，但是如果网站无法访问（不存在），则会打破其他需要它的调用，只需忽略并继续。这是由一个发布方法构建的，但现在需求已经改变。
我对线程的经验不多，但这是我创建线程所做的。
private void makethread(string Url, string useproxy, string xml)
{
//Parameters given put into list and passed with Thread.
var urls = new List<string>() { Url, useproxy, xml };
//Create thread
Thread t1 = new Thread(new ParameterizedThreadStart(HttpPost));
t1.Start(urls);
}
public void SetUrls()
{
String Url;
int count = 1;
string xml = CreateXML();
string useproxy = "(none)";
do
{
Url = objIniFile.GetString("Post", count.ToString(), "(none)");
useproxy = objIniFile.GetString("Post", count.ToString() + "Proxy", "(none)").ToUpper() ;
if (Url != "(none)")
{
// HttpPost(Url, xml , useproxy);
makethread(Url , useproxy , xml);
}
count++;
}
while (Url != "(none)");
}
SetUrls抓取URL并且是否需要使用代理并将其传递给上面的make thread方法，该方法传递xml，uri＆amp;代理作为HTTP Post的对象。
public void HttpPost(object urls)
{
string url= "none";
string xml= "none";
string useproxy = "none";
int count = 0;
//Splits Object to list and populate variables
foreach (var item in urls as List<string>)
{
if (count == 0) { url = item; }
if (count == 1) { useproxy = item; }
if (count == 2) { xml = item; }
count++;
}
string vystup = null;
string proxy = ProxyAddress;
string postData = xml;
//--------------
try
{
HttpRequestCachePolicy policy = new HttpRequestCachePolicy(HttpRequestCacheLevel.NoCacheNoStore);
HttpWebRequest.DefaultCachePolicy = policy;
byte[] buffer = Encoding.UTF8.GetBytes(postData);
//Initialisation
HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create(url);
//method is post
if (useproxy == "ON")
{
WebProxy myProxy = new WebProxy();
// Create a new Uri object.
Uri newUri = new Uri(proxy);
// Associate the new Uri object to the myProxy object.
myProxy.Address = newUri;
WebReq.Proxy = myProxy;
}
WebReq.KeepAlive = false;
WebReq.Method = "POST";
WebReq.ContentType = "application/x-www-form-urlencoded";
//The length of the buffer
WebReq.ContentLength = buffer.Length;
Stream PostData = WebReq.GetRequestStream();
//write, and close.
PostData.Write(buffer, 0, buffer.Length);
PostData.Close();
//Get the response handle
HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
//Let's show some information about the response
Console.WriteLine(WebResp.StatusCode);
Console.WriteLine(WebResp.Server);
//Do not worry about response!.
//read the response (the string), and output it.
Stream Answer = WebResp.GetResponseStream();
StreamReader _Answer = new StreamReader(Answer);
vystup = _Answer.ReadToEnd();
// MessageLog("Finished Posting " + DateTime.Now, "INFO");
if (vystup != "OK")
{
}
}
catch (WebException ex)
{
Console.WriteLine(ex);
}
}

如果我有2个工作网址，则可以使用。如果我尝试3个网址（其中第二个无效）第一个将完成，但另一个不会，即使第二个线程因超时退出！
我认为我没有正确使用线程，但我看不到任何帮助将被欣赏。
谢谢。
