WCF DataContract Attribute -

i have question [datacontract] attribute.

i have written code below: here not using [datacontract] attribute test class.

    class test     {       [datamember]        public string strproperty         {           get;           set;         }        [datamemer]        public string strproperty2         {           get;           set;         }     }    class checktotal:iservice     {     public string testmethod(test obj)        {            return obj.strproperty+strproperty2;        }     } 

for sending data client getting values correctly.

here necessary use [datacontract] attribute test class?

if removed [datamember] test class property getting error while sending client. not getting errors if not using [datacontract] attribute.

please give me brief explanation example can understand when give attribute , when not give attribute.

thanks, satya pratap.

the datacontractserializer can deal classes not have datacontract attribute if provide default constructor. see msdn documentation more details.
