Question

我使用MvcSiteMapProvider在Asp.net MVC 4中创建treeview导航器

我有2个链接：

〜/ Home / Article / {id}和〜/主页/图库/ {id}

我的Treeview像：主页 - ＆gt;文章 - ＆gt;画廊

我在Controller上使用了动态代码

    [MvcSiteMapNode(Title = "Article", ParentKey = "Home", Key="Article", PreservedRouteParameters="id")]
    public ActionResult Article(int id)
    {
        ViewBag.Id = id; 
        return View();
    }
    [MvcSiteMapNode(Title = "Gallery", Key="Gallery" ParentKey = "Article", PreservedRouteParameters="id")]
    public ActionResult Gallery(int id)
    {
        ViewBag.id = id;
        return View();
    }

所以它运行成功，但问题是我什么时候〜/ Home / Article / 123我去〜/ Home / Gallery / 456

接下来我点击树视图返回文章，它在文章中设置了错误的ID参数，它为文章的ID设置了图库ID：〜/ Home / Article / 456。

任何人都有解决者？抱歉我的英语很糟糕。

Answer 1

您可以明确设置参数的名称。

例如

[MvcSiteMapNode(Title = "Article", ParentKey = "Home", Key="Article", PreservedRouteParameters="ArticleId")]
public ActionResult Article(int ArticleId)
{
    ViewBag.Id = ArticleId; 
    return View();
}

[MvcSiteMapNode(Title = "Gallery", Key="Gallery" ParentKey = "Article", PreservedRouteParameters="GalleryId")]
public ActionResult Gallery(int GalleryId)
{
    ViewBag.id = GalleryId;
    return View();
}

然后：

/Home/Article/123

/Home/Gallery?GalleryId=456&ArticleId=123

MvcSiteMapProvider获取错误的Id参数
