StaticSiteMapProvider.Clear Method

Note: This method is new in the .NET Framework version 2.0.

Removes all elements in the collections of child and parent site map nodes that the StaticSiteMapProvider tracks as part of its state.

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

protected virtual void Clear ()
protected void Clear ()
protected function Clear ()

Classes that are derived from the StaticSiteMapProvider class can override the Clear method to perform additional cleanup, depending on what state the derived classes maintain.

The Clear method does not reset state that is initialized during the Initialize method—it resets only state that is initialized during the BuildSiteMap method.

The following code example demonstrates how to override the Clear method to perform additional cleanup of state that is maintained by the class.

This code example is part of a larger example provided for the StaticSiteMapProvider class.

// Clean up any collections or other state that an instance of this may hold.
protected override void Clear() {
    lock (this) {
        rootNode = null;
        base.Clear();
    }
}

// Clean up any collections or other state that an instance of this may hold.
protected void Clear()
{
    synchronized (this)
    {
        rootNode = null;
        super.Clear();
    }
} //Clear
