Question

我正在尝试在前端站点上构建辅助导航，但我无法解决问题。在下面的代码中，输出显示类似于：

// Loop through Root Webs in Site Collection
foreach (SPWeb TopLevelWebs in CurrentSite.AllWebs)
{
    SPNavigationNodeCollection FirstLevelWebs = TopLevelWebs.Navigation.GlobalNodes[0].Children;

    // Loop through each Child of Web
    foreach (SPNavigationNode FirstLevelWebChild in FirstLevelWebs)
    {
        // Skip over pages and only look at webs (or "Area" as it is called in 'Properties')
        if (FirstLevelWebChild.Properties["NodeType"].ToString() != "Page")
        {
            Response.Write(FirstLevelWebChild.Title + "<br />");

            SPNavigationNodeCollection SecondLevelWebs = FirstLevelWebChild.Navigation.GlobalNodes[0].Children;
            foreach (SPNavigationNode SecondLevelWebChild in SecondLevelWebs)
            {
                // Skip over pages and only look at webs (or "Area" as it is called in 'Properties')
                if (SecondLevelWebChild.Properties["NodeType"].ToString() != "Page")
                {
                    Response.Write("-----" + SecondLevelWebChild.Title + "<br />");
                }
            }
        }
    }
}

为什么上面的逻辑对顶级节点下的子网不起作用？我还没有完全理解“GlobalNodes”属性，所以我必须假设这就是问题所在。但我无法提出解决方案。

非常感谢任何帮助。

我知道这是从很久以前开始的，但是代码中有一个错误，因为谷歌的结果对我来说非常高，我想我应该为遇到它的其他人纠正它。

SPNavigationNodeCollection SecondLevelWebs = FirstLevelWebChild.Navigation.GlobalNodes [0] .Children;

应该是

SPNavigationNodeCollection SecondLevelWebs = FirstLevelWebChild.Children;

通过使用FirstLevelWebChild.Navigation.GlobalNodes，您再次获得根导航而不是您想要获得的子导航。

SPNavigation - 显示用户定义的导航
