Easily paginate collections in C#
In this post, we’ll create two extensions that lets us easily paginate any collection in C#.
When paginating a collection in C#, I find the following extensions useful:
public static IEnumerable<TSource> Paginate<TSource>(
this IEnumerable<TSource> source,
int? page,
int pageSize
) {
return source.Skip((page ?? 0) * pageSize).Take(pageSize);
}
public static IQueryable<TSource> Paginate<TSource>(
this IQueryable<TSource> source,
int? page,
int pageSize
) {
return source.Skip((page ?? 0) * pageSize).Take(pageSize);
}
With this, all IQueryable and IEnumerable instances automatically gets this functionality:
List<string> strings = new List<string> { "a","b","c","d","e","f" };
strings.Paginate(2, 2);
The pagination code above will return a list that contains “c” and “d”.
