    var TakingRequset = WebRequest.Create("http://xxx.acv.com/MethodName/Get");
    TakingRequset.Method = "POST";
    TakingRequset.ContentType = "text/xml;charset=utf-8";
    TakingRequset.PreAuthenticate = true;

    //---Serving Request path query
     var PAQ = TakingRequset.RequestUri.PathAndQuery;

    //---creating your xml as per the host reqirement
    string xmlroot=@"passing parameters";
    string xmlroot2=@"passing parameters";

    //---Adding Headers as requested by host 
    xmlroot2 = (xmlroot2 + "XXX---");
    //---Adding Headers Value as requested by host 
  //  var RequestheaderVales = Method(xmlroot2);

    WebProxy proxy = new WebProxy("XXXXX-----llll", 8080);
    proxy.Credentials = new NetworkCredential("XXX---uuuu", "XXX----", "XXXX----");
    System.Net.WebRequest.DefaultWebProxy = proxy;


    // Adding The Request into Headers
    TakingRequset.Headers.Add("xxx", "Any Request Variable ");
    TakingRequset.Headers.Add("xxx", "Any Request Variable");

    byte[] byteData = Encoding.UTF8.GetBytes(xmlroot);
    TakingRequset.ContentLength = byteData.Length;

    using (Stream postStream = TakingRequset.GetRequestStream())
    {
        postStream.Write(byteData, 0, byteData.Length);
        postStream.Close();
    }



    StreamReader stredr = new StreamReader(TakingRequset.GetResponse().GetResponseStream());
    string response = stredr.ReadToEnd();
