1、实验实验4设计模式设计模式要求n本周日最后一次实验时（12月23号晚18:0022:00），前三次未交作业的同学将作业补交。n本次实验为选做实验，设计模式的内容请大家自学。多年生植物型花园using System;namespace Gardener/ / Summary description for PerennialGarden./ public class PerennialGarden : Gardenpublic PerennialGarden() shade = new Plant(Astilbe);border = new Plant (Dicentrum);center =
2、new Plant (Sedum);用户界面Form用户界面单选按钮private void opAnnual_CheckedChanged(object sender, EventArgs e) setGarden( new AnnualGarden ();/-private void opVegetable_CheckedChanged(object sender, EventArgs e) setGarden( new VeggieGarden ();/-private void opPerennial_CheckedChanged(object sender, EventArgs e)
3、 setGarden( new PerennialGarden ();/-private void setGarden(Garden gd) garden = gd;/save current gardengdPic1.setGarden ( gd);/tell picture bosgdPic1.Refresh ();/repaint itckCenter.Checked =false;/clear allckBorder.Checked = false;/checkckShade.Checked = false;/boxes用户界面复选框private void ckCenter_Chec
