Answer 1

private TreeNode FindNode( TreeNode tnParent, string strValue )    {        if( tnParent == null ) return null;        if( tnParent.Text == strValue ) return tnParent;         TreeNode tnRet = null;        foreach( TreeNode tn in tnParent.Nodes )        {            tnRet = FindNode( tn, strValue );            if( tnRet != null ) break;        }        return tnRet;    }
 // 程序调用，如下：        TreeNode tnRet = null;        foreach( TreeNode tn in yourTreeView.Nodes )        {            tnRet =  FindNode( tn, yourValue );            if( tnRet != null ) break;        }
