c# - Deserializing a different List with protobuf-net -

i have problem deserialization protobuf-net. serialize list<> when deserialize list<> returned not identical first. there missing data. not understand why.

i initialize list<> in ctr

public ctr() {     datetime date = new datetime(2012 , 12, 03); ;     lkvisiteuriddto visitid= new lkvisiteuriddto(10, 11, 12);     purgedatetimedto datetime= new purgedatetimedto(date, true);     contractprotobuf proto = new contractprotobuf();      (int = 0; < 5; i++)     {         proto.m_index = + 1;         proto.m_technicalkey = "m_technicalkey" + i;         proto.m_logicalkey = visitid;         proto.m_purgetime = datetime;          protocontractlist.add(proto);     }  }  public byte[] serialization() {     memorystream ms = new memorystream();     try     {         serializer.serialize(ms, protocontractlist);         arr = ms.toarray();         return arr;     }     catch     {         console.writeline("la sérialisation protobuf échoué");         return null;     }         {         ms.close();     }  }  public list<contractprotobuf> deserialization() {     memorystream ms = new memorystream(arr,false);     try     {                      listeretour = serializer.deserialize<list<contractprotobuf>>(ms);         return (listeretour);     }     catch (exception e)     {         console.writeline("la désérialisation protobuf échoué");         return null;     }         {         ms.close();     } } 

so question how have same result ?

here structure

    [protocontract] public struct contractprotobuf {     [protomember(1)]     public int m_index;      [protomember(2)]     public string m_technicalkey;      [protomember(3)]     public lkvisiteuriddto m_logicalkey;      [protomember(4)]     public purgedatetimedto m_purgetime;  } 

i create list of contractprotobuf , add data values ​​"that not have consequence."

    public ctr()     { datetime date = new datetime(2012 , 12, 03); ;  (int = 0; < 5; i++) {     lkvisiteuriddto visitid= new lkvisiteuriddto(10, 11, 12);     purgedatetimedto datetime= new purgedatetimedto(date, true);     contractprotobuf proto = new contractprotobuf();     proto.m_index = + 1;     proto.m_technicalkey = "m_technicalkey" + i;     proto.m_logicalkey = visitid;     proto.m_purgetime = datetime;      protocontractlist.add(proto); }     

}

i serialize list gets byte [] , when deserialize byte [], return list not contain same values ​​in type purgedatetimedto , lkvisiteuriddto .

in return list find datetime {01/01/0001 0:00:00} , visitid {0,0,0} m.index , m_technicalkey have value

you don't show dtos, if assume contractprotobuf class, adding same instance each time. equally, adding same visit each time. normally, expect these different, example:

public ctr() {     datetime date = new datetime(2012 , 12, 03); ;      (int = 0; < 5; i++)     {         lkvisiteuriddto visitid= new lkvisiteuriddto(10, 11, 12);         purgedatetimedto datetime= new purgedatetimedto(date, true);         contractprotobuf proto = new contractprotobuf();         proto.m_index = + 1;         proto.m_technicalkey = "m_technicalkey" + i;         proto.m_logicalkey = visitid;         proto.m_purgetime = datetime;          protocontractlist.add(proto);     }     } 

but - impossible sure without more information. if can provide complete (i.e. runnable) example, i'll happy further.
