There are two ways to add 5000 nodes to the tree. I don't know if the performance is higher.The first is a single add.Treeview = new Treeview (); For (INT I = 0; I {Treenode node = new treenode (I. tostring ());Treeview. nodes. Add (node );} The second is to add a node set.Treeview = new Treeview (); Treenode [] nodes = new treenode [1, 5000];For (INT I = 0;
