hi to all.
I am serializing my object / converting it to XML data
and passing to another page and again Deserializing it.

i am using following function to serialize and Deserializing

public static string Serialize(object objectToSerialize)
     {
         MemoryStream mem = new MemoryStream();
         XmlSerializer ser = new XmlSerializer(objectToSerialize.GetType());
         ser.Serialize(mem, objectToSerialize);
         ASCIIEncoding ascii = new ASCIIEncoding();
         return ascii.GetString(mem.ToArray());
     }

     public static object Deserialize(string xmlString)
     {
         Type typeToDeserialize;
         byte[] bytes = Encoding.UTF8.GetBytes(xmlString);
         typeToDeserialize =xmlString.GetType();
         MemoryStream mem = new MemoryStream(bytes);
         XmlSerializer ser = new XmlSerializer(typeof (User ));
         return ser.Deserialize(mem);
     }

i have object User as

public class User
   {
       public string UserId { get; set; }
       public string Depatment { get; set; }
       public string Role { get; set; }
       internal byte[] FPTemplates { get; set; }
   }

now when i am serializing it i m getting only first three elements
FPTemplates which is byte[] it is not present in xml file
what should i do to get full serialization of object.??

plz help me...
thank in advance...:)
god bless u all.. :)

I see your issue.

Your byte array is internal make it public

XML

<pre lang="c#">
public  byte[] FPTemplates { get; set; }
</pre>

Try giving this a Go I see you are converting your string to utf8 and then ascii in your serialisers

C#

/// <summary>
        /// Serialize an object into an XML string
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="obj"></param>
        /// <returns></returns>
        public static string SerializeObject<t>(T obj)
        {
            try
            {
                string xmlString = null;
                MemoryStream memoryStream = new MemoryStream();
                XmlSerializer xs = new XmlSerializer(typeof(T));
                XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);
                xs.Serialize(xmlTextWriter, obj);
                memoryStream = (MemoryStream)xmlTextWriter.BaseStream;
                xmlString = Converters.ByteArrayToUTF8String(memoryStream.ToArray()); return xmlString;
            }
            catch
            {
                return string.Empty;
            }
        }

 /// <summary>
        /// Reconstruct an object from an XML string
        /// </summary>
        /// <param name="xml"></param>
        /// <returns></returns>
        public static T DeserializeObject<t>(string xml)
        {
            XmlSerializer xs = new XmlSerializer(typeof(T));
            MemoryStream memoryStream = new MemoryStream(Converters.StringToUTF8ByteArray(xml));
            XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);
            return (T)xs.Deserialize(memoryStream);
        }

public class Converters{
/// <summary>
        /// To convert a Byte Array of Unicode values (UTF-8 encoded) to a complete String.
        /// </summary>
        /// <param name="characters">Unicode Byte Array to be converted to String</param>
        /// <returns>String converted from Unicode Byte Array</returns>
        public static string ByteArrayToUTF8String(byte[] characters)
        {
            UTF8Encoding encoding = new UTF8Encoding();
            string constructedString = encoding.GetString(characters);
            return (constructedString);
        }
        /// <summary>
        /// Converts the String to UTF8 Byte array and is used in De serialization
        /// </summary>
        /// <param name="stringVal"></param>
        /// <returns></returns>
        public static Byte[] StringToUTF8ByteArray(string stringVal)
        {
            UTF8Encoding encoding = new UTF8Encoding();
            byte[] byteArray = encoding.GetBytes(stringVal);
            return byteArray;
        }
}
