c# - Object deep copy in Silverlight -

i trying create copy of objects in silverligth 5 interfaces iformatters , iccloanble not support. *

my objects this: (note these obkjects obtained on deserializing xml): tried copy this:

    [xmlroot(elementname = "component")]         public class component         {             [xmlelement("attributes")]             public attributes attributes { get; set; }               [xmlignore]             public attributes atrbtorginal = new attributes();             [xmlignore]             public attributes atrbtcopy{ get; set; }         }         public component()             {                           atrbtcopy= atrbtorginal ;             }  

sure not work got code on seraching on google :

 public static class objectcopier     {         public static t clone<t>(t source)         {             if (!typeof(t).isserializable)             {                 throw new argumentexception("the type must serializable.", "source");             }              // don't serialize null object, return default object             if (object.referenceequals(source, null))             {                 return default(t);             }             iformatter formatter = new binaryformatter();             stream stream = new memorystream();             using (stream)             {                 formatter.serialize(stream, source);                 stream.seek(0, seekorigin.begin);                 return (t)formatter.deserialize(stream);             }         }      }  , thought of doing liek this:  objectorginal.clone();. 

but problem in silverligth5 :

error   2   type or namespace name 'binaryformatter' not found (are missing using directive or assembly reference?)    error   1   type or namespace name 'iformatter' not found (are missing using directive or assembly reference?) 

is there alternative in silverlight 5 . please explain in detail. lot.

implement datacontractserializer attributes (datacontract, datamember) on classes , call datacontractserializer serialize memorystream, use again serialize out of memorystream new instance of object. far easiest understand, , quite performant too.

example of class definition :

[datacontract] class myclass {     [datamember]     public int myvalue {get;set;}     [datamember]     public string myothervalue {get;set;} } 

the method of cloning 1 class instance covered in microsoft documentation http://msdn.microsoft.com/en-us/library/ms752244(v=vs.110).aspx
