遇到这个错误：无法从用法中推导出方法

[gdmvip]

无法从用法中推导出方法“System.Web.Mvc.WebPage.GetPageList<T>(System.Linq.IOrderedQueryable<T>, int, int)”的类型实参。请尝试显式指定类型实参。
D:\项目练习\MvcTest\MvcApplication\MvcApplication\Areas\AdminManage\Controllers\AppLogoController.cs

下面是我的代码,我都贴出来了

Service

public IList<web_AppLogo> list()
        {
            try
            {
                var data = db.web_AppLogo.ToList();
                return data;
            }
            catch (Exception)
            {
                return null;
            }
        }

IService

public interface IAppLogoService
    {
        IList<web_AppLogo> list();
    }

Controller

public ActionResult List(int? id, int? Page)
        {
            var data = service.list();
            int PageSize = 10;
            int PageIndex = Page ?? 1;
            if (PageIndex < 1) PageIndex = 1;

            ViewData["PageIndex"] = PageIndex;
            ViewData["PageSize"] = PageSize;
            ViewData["ReCordCount"] = data.Count();
            return View(WebPage.GetPageList(data, PageIndex, PageSize));
        }

[gdmvip]

在Controller中的
return View(WebPage.GetPageList(data, PageIndex, PageSize));
提示那个错误

[gdmvip]

没人知道吗

[wowchina0753]

在Controller里面写查询 去掉 ToList();
