While looking into UCS XML API documentation, I wrote a simple c# code as a test to consume UCS XML API in c# console application. I thought it would be worth sharing. 
 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.IO;
using System.Xml;
 
 
 
namespace UCSAPIConsoleApp {
    class Program
    {
        static void Main(string[] args)
        {
 
            string sAuthCookie, sUsername, sPassword, sURI;
 
            try
            {
 
                Console.Write("Enter UCS URI(http:///nuova: ");
                sURI = Console.ReadLine();
 
                Console.Write("Enter username: ");
                sUsername = Console.ReadLine();
 
                Console.Write("Enter password: ");
                sPassword = Console.ReadLine();
 
                XmlDocument doc = new XmlDocument();
 
                doc.LoadXml(HTTPRequestResponse(sURI, ""));
                XmlNode xmln = doc.SelectSingleNode("/aaaLogin");
                sAuthCookie = xmln.Attributes["outCookie"].Value.ToString();
 
                Console.WriteLine("Auth Cookie:{0}", sAuthCookie);
                Console.WriteLine("=============================================================");
 
                doc.LoadXml(HTTPRequestResponse(sURI, ""));
 
                xmln = doc.SelectSingleNode("/configResolveDn/outConfig/computeBlade");
 
                for (int i = 0; i < xmln.Attributes.Count; i++)
                    Console.WriteLine("{0}={1}", xmln.Attributes.Name, xmln.Attributes.Value);
 
                doc.LoadXml(HTTPRequestResponse(sURI, ""));
                xmln = doc.SelectSingleNode("/aaaLogout");
 
                Console.WriteLine("=============================================================");
                Console.WriteLine("Logout={0}", xmln.Attributes["outStatus"].Value.ToString());
 
                Console.ReadKey();
 
            }
            catch (Exception ex)
            {
                Console.WriteLine("Error occurred while execution:{0}", ex.Message);
            }
        }
 
 
 
 
        private static string HTTPRequestResponse(string sURL, string strXML)
        {
            byte[] XMLbuffer = Encoding.UTF8.GetBytes(strXML);
 
            try
            {
 
                HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create(sURL);
 
                WebReq.Method = "POST";
 
                WebReq.ContentType = "text/xml";
 
                WebReq.ContentLength = XMLbuffer.Length;
 
                Stream PostData = WebReq.GetRequestStream();
 
                PostData.Write(XMLbuffer, 0, XMLbuffer.Length);
                PostData.Close();
 
                using (HttpWebResponse WebResponse = (HttpWebResponse)WebReq.GetResponse())
                {
 
                    Stream response = WebResponse.GetResponseStream();
 
                    return new StreamReader(response).ReadToEnd();
                }
 
            }
            catch(Exception ex)
            {
                Console.WriteLine("Exception occurred: {0}", ex.Message);
                return null;
 
            }
 
 
        } 
 
 
    }
}
 
 
OUTPUT:
