丽兹，

我认为这个问题已经被提出，但这是我所指的问题：Paging & Sorting grids with ASP.Net MVC

此外，这是一个非常简洁的教程，介绍如何执行此操作：
http://xlib.wordpress.com/2009/06/29/asp-net-mvc-grid-%E2%80%93-part-2-paging/

以上链接中的一些片段：

使用此选项可在页面上获取选择器，以允许用户确定每页显示的行数：

<%= Html.DropDownList("pageSize", CustomerController.PageSizeSelectList(), new { onchange = "onPageSizeChange()" })%> rows per page

然后在自定义页面控制器中编写此代码：

public static SelectList PageSizeSelectList()
{
    var pageSizes = new List {"1", "2", "5", "10", "100"};
    return new SelectList(pageSizes, "Value");
}

现在将JavaScript添加到页面中：

//Set hidden variable to go to next/prev/last/first page and submit the form
function goToPage(pageIndex) {
    $("#currentPage").val(pageIndex);
    $("#gridAction").val("CurrentPageChanged");

    submitForm();
}

//Set action performed in hidden variable. When PageSize changes - PageIndex needs to be
//reset to 1. This logic will go on the server side.
function onPageSizeChange(pageIndex) {
    $("#gridAction").val("PageSizeChanged");
    submitForm();
}

function submitForm() {
    var form = $("#grid").parents("form:first");
    form.submit();
}

然后更新您的页面控制器以执行分页：

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult List(int currentPage, int pageSize, string gridAction)
{
        //Do logic depending on what action was performed
    if (gridAction == "PageSizeChanged")
        currentPage = 1;

        //Check if there are no results.  In this case return empty list.
    IQueryable query = _customerService.GetQueryable();
    int totalRows = query.Count();
    if (totalRows==0)
        return View(new List());

    int totalPages = (int)Math.Ceiling((double)totalRows / (double)pageSize);
    if (totalPages != 1)
    {
        //use LINQ to perform paging
        query = query.Skip((currentPage - 1) * pageSize)
                        .Take(pageSize);
    }

        //Update ViewData collection to display pager stats and pager controls
    UpdatePagerViewData(totalPages, totalRows, currentPage, pageSize);

    List customers = query.ToList();
    return View(customers);
}

我希望这有帮助，
