Answer 1

I always use the following code:

public static class PagingExtensions
{
    //used by LINQ to SQL
    public static IQueryable<TSource> Page<TSource>(this IQueryable<TSource> source, int page, int pageSize)
    {
        return source.Skip((page - 1) * pageSize).Take(pageSize);
    }

    //used by LINQ
    public static IEnumerable<TSource> Page<TSource>(this IEnumerable<TSource> source, int page, int pageSize)
    {
        return source.Skip((page - 1) * pageSize).Take(pageSize);
    }

}

That is a static class, which you can include in your sources. After adding this class you can do the following:

MyQuery.Page(pageNumber, pageSize)
