值？将路由参数修改为

new{new{OrderBy=ViewBag.SortOrder，page，pageSize=Model.pageSize}

然后在控制器中，在返回视图之前添加

ViewBag.SortOrder=OrderBy；

。但是如果视图模型具有所需的所有属性，效果会更好。@stephenmueke你的评论真的帮了我大忙！非常感谢！我已经成功了。你能给我举一个关于视图模型的例子吗？我是个初学者，我已经学会了一个是这样的，但我不知道为什么在运行应用程序时会出现此错误：方法“Skip”仅支持LINQ to Entities中的排序输入。方法“OrderBy”必须在方法“Skip”之前调用。我的代码中没有Skip方法。我已经搜索了它，但找不到它。

.Skip（）

被

PagedList

调用。很抱歉，我刚才复制了您的代码部分（您的代码也会出现此错误）。添加

其他{products=products.OrderBy（p=>p.someproperty）}

（可能是

ID

属性）因此，在调用

PagedList

之前，您可以获得一个有序的集合，当我转到时，它可以工作，但当我直接转到时，它不工作
