c# - Make ToolStripItemCollection Property -

how can make toolstripitemcollection property contextmenustrip. thought simple this

contextmenustrip _menu = new contextmenustrip(); public toolstripitemcollection menuitems {     { return _menu.items; }     set { _menu.items = value; } } 

but not work.

instead in set this:

public toolstripitemcollection menuitems {    { return _menu.items; }    set     {       _menu.items.clear();       foreach(var elem in value)       {          _menu.items.add(elem);       }    } }
