HTTP POST using web service

Question

I have been doing some Google searches and only getting partial successful on this topic. I was wondering if someone could suggest an example of doing an HTTP POST using C# to send XML to HTTP service.

I have a asmx web service that extracts data from database and I save that data to XML document. Now I have to send that XML document using SOAP protocol to HTTP service.

I have this part of code for connectig to service

WebRequest myReq = WebRequest.Create("https://WEB_URL");
 System.Net.ServicePointManager.CertificatePolicy = new CertificatePolicyClass();

                string username = "SOMETHING";
                string password = "ELSE";
                string usernamePassword = username + ":" + password;
                CredentialCache mycache = new CredentialCache();
                mycache.Add(new Uri("https://WEB_URL"), "Basic", new  NetworkCredential(username, password));
                myReq.Credentials = mycache;
                myReq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(usernamePassword)));

                WebResponse wr = myReq.GetResponse();
                Stream receiveStream = wr.GetResponseStream();
                StreamReader reader = new StreamReader(receiveStream, Encoding.UTF8);
                string content = reader.ReadToEnd();

So does anybody have a code to send XML document to http service, this part I don't know how to write, I don't know am I on the write trace, I belive it has to go somethig like this

request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";

So plese can somebody help me! THANKS!

Here is something I get, hope it's useful to you:

HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("https://WEB_URL");
myReq.Method = "POST";
myReq.ContentType = "text/xml";
myReq.Timeout = 30000;
myReq.Headers.Add("SOAPAction", ":\"#save\"");

byte[] PostData = Encoding.UTF8.GetBytes(xmlDocument);
myReq.ContentLength = PostData.Length;

using (Stream requestStream = myReq.GetRequestStream())
{
    requestStream.Write(PostData, 0, PostData.Length);
}

HttpWebResponse response = (HttpWebResponse)myReq.GetResponse();
