SiteMapNode.GetAllNodes 方法

定义

命名空间:

System.Web

程序集:

System.Web.dll

检索属于调用节点的子代的所有 SiteMapNode 对象的只读集合，而不管分离程度如何。

public:
 System::Web::SiteMapNodeCollection ^ GetAllNodes();

public System.Web.SiteMapNodeCollection GetAllNodes ();

member this.GetAllNodes : unit -> System.Web.SiteMapNodeCollection

Public Function GetAllNodes () As SiteMapNodeCollection

返回

SiteMapNodeCollection

表示当前提供程序范围内的某个 SiteMapNodeCollection 的所有子代的只读 SiteMapNode。

示例

下面的代码示例演示如何使用GetAllNodes该方法检索所有子节点RootNode。

SiteMapNodeCollection siteNodes = SiteMap.RootNode.GetAllNodes();

if ( siteNodes.IsReadOnly ||
     siteNodes.IsFixedSize )
{
    Response.Write("Collection is read-only or has fixed size.<BR>");

    // Create a new, modifiable collection from the existing one.
    SiteMapNodeCollection modifiableCollection =
         new SiteMapNodeCollection(siteNodes);

    // The MoveNode example method moves a node from position one to
    // the last position in the collection.
    MoveNode(modifiableCollection);
}
else {
    MoveNode(siteNodes);
}

Dim siteNodes As SiteMapNodeCollection
siteNodes = SiteMap.RootNode.GetAllNodes()

If siteNodes.IsReadOnly Or siteNodes.IsFixedSize Then

    Response.Write("Collection is read-only or has fixed size.<BR>")

    ' Create a new, modifiable collection from the existing one.
    Dim modifiableCollection As SiteMapNodeCollection
    modifiableCollection = New SiteMapNodeCollection(siteNodes)

    ' The MoveNode example method moves a node from position one to
    ' the last position in the collection.
    MoveNode(modifiableCollection)
Else
    MoveNode(siteNodes)
End If

注解

此方法以递归方式检索即时子节点及其所有子节点。
