Clone(Boolean)

現在のノードのコピーである新しいノードを作成します。オプションで、現在のノードのすべての親ノードと先祖ノードを複製できます。Creates a new copy that is a copy of the current node, optionally cloning all parent and ancestor nodes of the current node.

public:
 virtual System::Web::SiteMapNode ^ Clone(bool cloneParentNodes);
public virtual System.Web.SiteMapNode Clone (bool cloneParentNodes);
abstract member Clone : bool -> System.Web.SiteMapNode
override this.Clone : bool -> System.Web.SiteMapNode

パラメーター

cloneParentNodes
Boolean

現在のノードのすべての親ノードと先祖ノードを複製する場合は true。それ以外の場合は falsetrue to clone all parent and ancestor nodes of the current node; otherwise, false.

戻り値

SiteMapNode

現在のノードのコピーである新しいノード。A new node that is a copy of the current node.

次のコード例は、Clone メソッドを呼び出して、現在のノードから複製したサイトマップノードを作成する方法を示しています。The following code example demonstrates how to call the Clone method to create a duplicate site map node from the current node. ExpandForumPaths メソッドは、SiteMapResolve イベントを処理するように登録されています。The ExpandForumPaths method is registered to handle the SiteMapResolve event. Clone メソッドを使用して、現在のサイトマップノードの作業コピーを作成し、パーソナル化データに基づいて属性を変更して、作業コピーを返します。It uses the Clone method to create a working copy of the current site map node, modify attributes based on personalization data, and return the working copy.

private void Page_Load(object sender, EventArgs e)
{
    // The ExpandForumPaths method is called to handle
    // the SiteMapResolve event.
    SiteMap.SiteMapResolve +=
      new SiteMapResolveEventHandler(this.ExpandForumPaths);
}

private SiteMapNode ExpandForumPaths(Object sender, SiteMapResolveEventArgs e)
{
    // The current node represents a Post page in a bulletin board forum.
    // Clone the current node and all of its relevant parents. This
    // returns a site map node that a developer can then
    // walk, modifying each node.Url property in turn.
    // Since the cloned nodes are separate from the underlying
    // site navigation structure, the fixups that are made do not
    // effect the overall site navigation structure.
    SiteMapNode currentNode = SiteMap.CurrentNode.Clone(true);
    SiteMapNode tempNode = currentNode;

    // Obtain the recent IDs.
    int forumGroupID = GetMostRecentForumGroupID();
    int forumID = GetMostRecentForumID(forumGroupID);
    int postID = GetMostRecentPostID(forumID);

    // The current node, and its parents, can be modified to include
    // dynamic querystring information relevant to the currently
    // executing request.
    if (0 != postID)
    {
        tempNode.Url = tempNode.Url + "?PostID=" + postID.ToString();
    }

    if ((null != (tempNode = tempNode.ParentNode)) &&
        (0 != forumID))
    {
        tempNode.Url = tempNode.Url + "?ForumID=" + forumID.ToString();
    }

    if ((null != (tempNode = tempNode.ParentNode)) &&
        (0 != forumGroupID))
    {
        tempNode.Url = tempNode.Url + "?ForumGroupID=" + forumGroupID.ToString();
    }

    return currentNode;
}
Private Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

    ' The ExpandForumPaths method is called to handle
    ' the SiteMapResolve event.
    AddHandler SiteMap.SiteMapResolve, AddressOf Me.ExpandForumPaths

End Sub

Private Function ExpandForumPaths(ByVal sender As Object, ByVal e As SiteMapResolveEventArgs) As SiteMapNode
    ' The current node represents a Post page in a bulletin board forum.
    ' Clone the current node and all of its relevant parents. This
    ' returns a site map node that a developer can then
    ' walk, modifying each node.Url property in turn.
    ' Since the cloned nodes are separate from the underlying
    ' site navigation structure, the fixups that are made do not
    ' effect the overall site navigation structure.
    Dim currentNode As SiteMapNode = SiteMap.CurrentNode.Clone(True)
    Dim tempNode As SiteMapNode = currentNode

    ' Obtain the recent IDs.
    Dim forumGroupID As Integer = GetMostRecentForumGroupID()
    Dim forumID As Integer = GetMostRecentForumID(forumGroupID)
    Dim postID As Integer = GetMostRecentPostID(forumID)

    ' The current node, and its parents, can be modified to include
    ' dynamic querystring information relevant to the currently
    ' executing request.
    If Not (0 = postID) Then
        tempNode.Url = tempNode.Url & "?PostID=" & postID.ToString()
    End If

    tempNode = tempNode.ParentNode
    If Not (0 = forumID) And Not (tempNode Is Nothing) Then
        tempNode.Url = tempNode.Url & "?ForumID=" & forumID.ToString()
    End If

    tempNode = tempNode.ParentNode
    If Not (0 = ForumGroupID) And Not (tempNode Is Nothing) Then
        tempNode.Url = tempNode.Url & "?ForumGroupID=" & forumGroupID.ToString()
    End If

    Return currentNode

End Function

注釈

cloneParentNodes パラメーターが trueの場合、Clone メソッドはすべての直接の先祖ノードを再帰的に複製し、現在複製されているノードに関連付けます。If the cloneParentNodes parameter is true, the Clone method recursively clones all direct ancestor nodes and associates them with the current cloned node. 子ノードは複製されません。Child nodes are not cloned.

Roles コレクションと Attributes コレクションは、新しいコレクションに適用されます。The Roles and Attributes collections are applied to new collections.
