SiteMapNodeCollection.AddRange Method (SiteMapNodeCollection)

Adds the nodes in the specified SiteMapNodeCollection to the current collection.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

public virtual void AddRange(
	SiteMapNodeCollection value
)

Parameters

value
Type: System.Web.SiteMapNodeCollection

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

ExceptionCondition
ArgumentException

value is null.

NotSupportedException

The SiteMapNodeCollection is read-only.

The SiteMapNodeCollection collection that is passed to the AddRange method can contain null SiteMapNode objects; however, this leads to unexpected exceptions when the SiteMapNodeCollection is manipulated.

You cannot add a SiteMapNode object to a read-only or fixed-size SiteMapNodeCollection. You can test whether a SiteMapNodeCollection is read-only by checking the IsReadOnly property.

The following code example demonstrates how to create a modifiable SiteMapNodeCollection collection, and then add SiteMapNode objects to it using the AddRange method.

// Create a SiteMapNodeCollection with all the nodes 
// from the first two hierarchical levels of the current 
// site map.
SiteMapNodeCollection baseCollection =
    new SiteMapNodeCollection(SiteMap.RootNode);

SiteMapNodeCollection childCollection =
    SiteMap.RootNode.ChildNodes;

baseCollection.AddRange(childCollection);

Response.Write( "<BR>Derived SiteMapNodeCollection.<BR><HR><BR>");
foreach (SiteMapNode node in baseCollection) {
    Response.Write( node.Title + "<BR>");
}
