c# - How to use the update method for a generic LINQ to SQL repository -

i have implemented following generic methods:

public iqueryable<t> query(expression<func<t, bool>> filter) {     return context.gettable<t>().where(filter); }  public virtual void update(t entity) {     context.gettable<t>().attach(entity);         } 

i not sure how implement in consumer class? ideally, pass in userref , update user accordingly?

change to:

public iqueryable<t> query<t>(expression<func<t, bool>> filter) {     return context.gettable<t>().where(filter); }  public virtual void update<t>(t entity) {     context.gettable<t>().attach(entity);         }  var user=something.query<user>(x=>x.name=="bla bla").first; user.name="alb alb"; something.update(user); 

but consider avoiding writing generic repositories. don't gain them. if it's generic, exposes iqueryable, takes in expression filters, it's quite useless abstraction layer , adds complexity.
