Create Xml string using Memorystream in C#

public static void Main()
        {
            string resultString = GetInputXml();
            Console.WriteLine(resultString);
            Console.Read();
        }

        private static string CreateXml()
        {
            MemoryStream memoryStream = null;
            XmlTextWriter xmlTextWriter = null;
            StreamReader streamReader = null;
            string xmlOutput = string.Empty;

            try
            {
                memoryStream = new MemoryStream();
                xmlTextWriter = new XmlTextWriter(memoryStream, System.Text.Encoding.UTF8);

                //xmlTextWriter.WriteStartDocument();
                xmlTextWriter.Formatting = Formatting.Indented;

                xmlTextWriter.WriteStartElement("Root");

                xmlTextWriter.WriteElementString("Id", "1001");
                xmlTextWriter.WriteElementString("Status", "Closed");
                xmlTextWriter.WriteElementString("SourceID", "S001");
                xmlTextWriter.WriteFullEndElement();
                xmlTextWriter.Flush();

                memoryStream.Position = 0;
                streamReader = new StreamReader(memoryStream);
                xmlOutput = streamReader.ReadToEnd();

                xmlTextWriter.Close();
                streamReader.Close();
            }
            catch (Exception ex)
            {
                throw new ApplicationException("Error creating input xml in GetInputXml method.");
            }
            return xmlOutput;
        }

Output:

<Root>
<Id>1001</Id>
<Status>Closed</Status>
<SourceID>S001</SourceID>
</Root>
