分页助手 ASP.NET MVC

我已经实现了一个分页 HTML 帮助器（改编自 Steven Sanderson 的书）。这是当前的代码：

public static string PageLinks(this HtmlHelper html, int currentPage, int totalPages, Func<int, string> pageUrl)
{
    StringBuilder result = new StringBuilder();

    for (int i = 1; i <= totalPages; i++)
    {
        TagBuilder tag = new TagBuilder("a");
        tag.MergeAttribute("href", pageUrl(i));
        tag.InnerHtml = i.ToString();
        if (i == currentPage)
            tag.AddCssClass("selectedPage");
        result.AppendLine(tag.ToString());
    }

    return result.ToString();
}

这会生成一堆指向我的项目的每个页面的链接。如果有很多页面，这可能会有点让人不知所措。我正在寻找一个类似的实现，它会产生一些不那么压倒性的东西，如下所示：

<previous ... 5 6 7 ... next>

其中 6 是当前页面。我确信在我必须重新实现轮子之前，一定有人已经实现了类似的东西？

I have implemented a paging HTML helper (adapted from Steven Sanderson's book). This is the current code:

public static string PageLinks(this HtmlHelper html, int currentPage, int totalPages, Func<int, string> pageUrl)
{
    StringBuilder result = new StringBuilder();

    for (int i = 1; i <= totalPages; i++)
    {
        TagBuilder tag = new TagBuilder("a");
        tag.MergeAttribute("href", pageUrl(i));
        tag.InnerHtml = i.ToString();
        if (i == currentPage)
            tag.AddCssClass("selectedPage");
        result.AppendLine(tag.ToString());
    }

    return result.ToString();
}

This produces a bunch of links to each page of my items. If there are many pages this can be a bit overwhelming. I am looking for a similar implementation which produces something less overwhelming like this:
