.net - C# unit of work repository pattern -

i'm trying use repository pattern unit of work. use c# , entity framework , purpose use reporitory connect different data sources single controller, can't implement it.

this scenario:

i have 2 different data source:

• sqlserver entity framework read , write data

• web service retrieve data.

i use unit of work access 2 data sources interchangeably.

this repository:

class genericrepository<t> : irepository<t> t : class {     private dbentities entities = null;     iobjectset<t> _objectset;      public genericrepository(dbentities _entities)     {         entities = _entities;         _objectset = entities.createobjectset<t>();     }      public ienumerable<t> getall(string uri, string ragneuri)     {         ienumerable<t> t = new list<t>();         return t.asenumerable();     }      public ienumerable<t> getall(func<t, bool> predicate = null)     {         if (predicate != null)   {       return _objectset.where(predicate);   }    return _objectset.asenumerable();     }      public t get(func<t, bool> predicate)     {   return _objectset.first(predicate);     }      public void add(t entity)     {   _objectset.addobject(entity);     }      public void attach(t entity)     {   _objectset.attach(entity);     }      public void delete(t entity)     {   _objectset.deleteobject(entity);     } } 

and it's unit of work

public class genericunitofwork : idisposable {     private dbentities entities = null;     private dataactions da = null;      public genericunitofwork(dbentities pe)     {         entities = pe;     }      public dictionary<type, object> repositories = new dictionary<type, object>();      public irepositoryipse<t> repository<t>() t : class     {         if (repositories.keys.contains(typeof(t)) == true)         {             return repositories[typeof(t)] irepository<t>;         }         irepository<t> repo = new genericrepository<t>(entities);         repositories.add(typeof(t), repo);         return repo;     }      public void savechanges()     {         entities.savechanges();     }      private bool disposed = false;      protected virtual void dispose(bool disposing)     {         if (!this.disposed)         {             if (disposing)             {                 entities.dispose();             }         }         this.disposed = true;     }      public void dispose()     {         dispose(true);         gc.suppressfinalize(this);     } } 

now succeed connect @ data base, don't connect web service.

to access web service create second repository single method getdata(), don't know how integrate unit of work , use different repository interchangeably. there different way resolve problem?

thank's
