How to avoid copying the reference in linq C#

Hi All,

I have following queries - 

  currObject = (from obj in objectEntity.parts
                       where obj.pKey.Equals(cKey)
                       select obj).FirstOrDefault();

  newObject = (from obj in objectEntity.parts
                       where obj.pKey.Equals(cKey)
                       select obj).FirstOrDefault();

 Here both above linqs are same. If I used -

 newObject = currObject

 It will copy the reference which I don't want. I want both the object independent on each other using 1 query.

Please help me.
