SiteMapNodeCollection::AddRange Method (SiteMapNodeCollection)
Adds the nodes in the specified SiteMapNodeCollection to the current collection.
Assembly: System.Web (in System.Web.dll)
Parameters
- value
- Type: System.Web::SiteMapNodeCollection
A SiteMapNodeCollection that contains the SiteMapNode objects to add to the current SiteMapNodeCollection.
| Exception | Condition |
|---|---|
| ArgumentException | value is nullptr. |
| NotSupportedException | The SiteMapNodeCollection is read-only. |
The SiteMapNodeCollection collection that is passed to the AddRange method can contain nullptr 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.
