Im using EntityFramework Code First Generic Repository. I have one filter method. Also this method make paging and sorting. Method like below
public IQueryable Filter(Expression> filter, out int total, Expression> sorting, SortType sortDirection, int index = 1, int size = 30)
{
index = index - 1;
int skipcount = index * size;
IQueryable resetSet = filter != null ? Entities.Where(filter) : Entities.AsQueryable();
total = Entities.Where(filter).Count();
if (sortDirection == SortType.Desc)
{
resetSet = skipcount == 0 ?
resetSet.Where(filter).OrderByDescending(sorting).Skip(0).Take(size) :
resetSet.Where(filter).OrderByDescending(sorting).Skip(skipcount).Take(size);
}
else
{
resetSet = skipcount == 0 ?
resetSet.Where(filter).OrderBy(sorting).Skip(0).Take(size) :
resetSet.Where(filter).OrderBy(sorting).Skip(skipcount).Take(size);
}
return resetSet.AsQueryable();
}
Type of sorting is Expression> If i pass this parameter as Expression> getting an exception invalid casting between int to object but Expression> dosent throw any exception..
Any idea Thanks
