[OnDeserialized] and OnDeserialization() allows to change ALL fields after deserialization RRS feed

  • Question

  • Hi,

    Is it right that OnDeserialized attribute and OnDeserialization interface method both allows us to modify any field in the object?

    For example,

        class Rectangle: IDeserializationCallback
            public int len, width;
            public int area;
            public Rectangle()
                len = 1;
                width = 2;
                area = len*width;
            public void ondeserialized(StreamingContext s)
                area  = len*width;
                len   = 2;
                width = 5;
            public void OnDeserialization(object sender)
                 area  = len*width;
                 len   = 6;
                 width = 7;             

    Now after this Rectangle object is deserialized, Area doesn't match with the length and width fields. 

    I just became curious if this is purely a developer design error or we should have some preventive ways to stop these?

  • Hi KVRagava,

    Thank you for posting here.

    For your question, based onmy test, we could change field's value after deserialization. This not a error. There is no MSDN document said that we could not change it.
