    The TreeView class has a SelectedNode property that holds the currently selected TreeNode.

    TreeNode tn = ctl_treeView.SelectedNode;

if ( tn == null )
    Console.WriteLine("No tree node selected.");
else
    Console.WriteLine("Selected tree node {0}.", tn.Name );

    You can compare the returned TreeNode reference to the TreeNode you’re looking for, and so check if it’s currently selected.
