I am using treeview in C# and VS2005

if ((tempnode1 = tempnode1.NextVisibleNode) != null);

I am not able to handle the null reference returned by this statement at the last node of the treeview. Can anyone please suggest a statement to check for null returned by TreeNode.NextVisibleNode

Thanks.

    How about something like …

    if( tempnode1 != null && tempnode1.NextVisibleNode != null )
{
  tempnode1 = tempnode1.NextVisibleNode;
}

    It’s a bit more defensive and a bit more readable.
