How do i covert a List colletion to XML?

Hi, 

Below is your code, But dont forget to mark my answer as accepted if it helped you a little

using System.Xml.Serialization;
[System.Xml.Serialization.XmlRootAttribute(Namespace="", IsNullable=false)]
public class User 
{ 
      public property string userCode{get;set;} 
      public property string userName{get;set;} 
} 
 
following is you function

 /// <summary>

  /// Returns the xml as string based on user object values

  /// </summary>

  /// <param name="user">object that would be converted into xml</param>

  /// <returns></returns>

  public string UserXml(User user)
  {
   MemoryStream stream = null;
   TextWriter writer = null;
   try
   {
    stream = new MemoryStream(); // read xml in memory

    writer = new StreamWriter(stream, Encoding.Unicode) ;
    // get serialise object

    XmlSerializer serializer = new XmlSerializer(typeof(user));
    serializer.Serialize(writer, user); // read object

    int count = (int) stream.Length; // saves object in memory stream

    byte[] arr = new byte[count];
    stream.Seek(0, SeekOrigin.Begin);
    // copy stream contents in byte array

    stream.Read(arr, 0, count);
    UnicodeEncoding utf = new UnicodeEncoding(); // convert byte array to string

    return utf.GetString(arr).Trim();
   }
   catch
   {
    return string.Empty;
   }
   finally
   {
    if(stream != null) stream.Close();
    if(writer != null) writer.Close();
   }
  }
