Generic Repository with Object Context in Linq

Generic Repository with Object Context

Generic Class :

public class GenericRepository<T> : IDisposable where T : class

    {

        private XSharingEntities _ObjContext;

        IObjectSet<T> objSet;

        public GenericRepository(XSharingEntities context)

        {

            _ObjContext = context;

            objSet = _ObjContext.CreateObjectSet<T>();

        }

        public void Insert(T entity)

        {           

            if (entity != null)

            {

                objSet.Attach(entity);

                objSet.AddObject(entity);

            }

        }

        public void Delete(T entity)

        {

            if (entity != null)

            {

                objSet.DeleteObject(entity);

            }

        }

        public T getDetail(Expression<Func<T, bool>> where)

        {

            return objSet.Where(where).FirstOrDefault();

        }

        public IEnumerable<T> GetList()

        {

            return objSet.ToList();

        }

        public IEnumerable<T> GetList(Expression<Func<T,bool>> where)

        {

            return objSet.Where(where).ToList();

        }

        public void Save()

        {           

            _ObjContext.SaveChanges();

        }

        public void Dispose()

        {

            _ObjContext.Dispose();

            GC.SuppressFinalize(this);

        }

    }

Use generic class in our code

XSharingEntities objContext = new XSharingEntities();

public GenericRepository<SharingComment> objCFSCode

{

    get

    {

       GenericRepository<SharingComment> obj =

      new GenericRepository<SharingComment>(objContext);

      return obj;

    }

}

Do openrations in User Code

using (objCFSCode)

            {

                /// For Update

                var cmnt = objCFSCode.getDetail(p => p.CommentPK == 60217);               

                cmnt.Comment = "for Now";

                cmnt.CommentDate = DateTime.Now;

                cmnt.NotificationFK = 14;

                cmnt.UserFK = 1;

                objCFSCode.Save();

                // For Insert  

                SharingCFSCode obj = new SharingCFSCode();

                // SharingCFSCode is table

                obj.Application = "Test";

                obj.CFSCode = "AAAAAA";

                obj.CFSDescription = "This is Test CFS";

                obj.CFSPK = 123458;

                objCFSCode.Insert(cmnt);

                objCFSCode.Save();

                // for Delete

                objCFSCode.Delete(cmnt);

                objCFSCode.Save();

            }
