SiteMapNodeCollection Constructor (SiteMapNodeCollection)

Initializes a new instance of the SiteMapNodeCollection class and adds all the list items of the specified SiteMapNodeCollection collection to the InnerList property for the collection.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)
public SiteMapNodeCollection(
	SiteMapNodeCollection value


Type: System.Web.SiteMapNodeCollection

A SiteMapNodeCollection that contains the SiteMapNode to add to the current SiteMapNodeCollection.


value is null.

Using the SiteMapNodeCollection constructor is equivalent to calling the SiteMapNodeCollection constructor and adding elements to the SiteMapNodeCollection collection with the AddRange method.

The following code example demonstrates how to create a SiteMapNodeCollection collection using another SiteMapNodeCollection of SiteMapNode objects as a base. The SiteMapNode.GetAllNodes method returns a read-only SiteMapNodeCollection, which is detected when the IsReadOnly property returns true. A new SiteMapNodeCollection is created using the read-only SiteMapNodeCollection and the Add and Remove methods can be called successfully.

    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.
    else {
