江苏开放大学NET平台与C#程序设计第四次形考作业

江苏开放大学NET平台与C#程序设计第四次形考作业实验名称：一、实验目的及要求1.使用文本框、按钮、标签、复选框、单选按钮等控件2.查找和修正语法错误二、实验内容1.设计与演示普通自助用餐费用预算功能的实现2.设计与演示宴会用餐费用预算功能的实现三、实验设备及环境1.安装visualstudio2010软件四、实验步骤（功能实现的核心代码及说明）本实验以综合实验讲义中的案例作为本次形考作业，任务一：实现启动“订餐小精灵”的设计设计与开发,实现普通自助用餐费用预算功能，程序运行默认状态图、改变选项值后的效果图、用餐人数为50的程序运行效果图、当前输入用餐人数超过40人时的程序运行效果图把实验的相关代码复制到word文档中，并把代码运行的相关运行结果图截屏存放在代码的下面。usingSystem;publicclassCustomer{publicstringcustomerName;//姓名publicboolmemberOption;//是否会员publicstringphoneNumber;//联系电话publicvoidSetMemberOption(booloption){memberOption=option;}}usingSystem;usingSystem.Windows.Forms;publicclassDinner{publicconststringtype=“自助用餐”;//用餐类型publicconstintcostOfFoodPerPerson=35;//人均食品费用publicdecimalcostOfBeveragesPerPerson;//人均饮料费用publicCustomercustomer;//客户publicDateTimedate;//日期时间privatedecimalcost;//总费用publicdecimalCost{get{returncost;}set{cost=value;}}privateintnumberOfPeople;//用餐人数publicintNumberOfPeople{get{returnnumberOfPeople;}set{if(value>40){MessageBox.Show(“超过40人，无法下订单”);return;}else{numberOfPeople=value;}}}publicDinner(intnumberOfPecple){customer=newCustomer();this.numberOfPeople=numberOfPecple;//初始化人数为5}publicvoidSetWineOption(boolwineOption){//人均饮料费if(wineOption){costOfBeveragesPerPerson=40.00M;}else{costOfBeveragesPerPerson=15.00M;}}publicdecimalCalculateCost()//返回总费用{decimaltotalCost=(costOfFoodPerPerson+costOfBeveragesPerPerson)*numberOfPeople;if(customer.memberOption){this.cost=totalCost*0.85M;returntotalCost*0.85M;}else{this.cost=totalCost;returntotalCost;}}}usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;usingSystem.Windows.Forms;namespaceSpiritKitchen{publicpartialclassSpiritKitchen:Form{Dinnerdinner;publicSpiritKitchen(){InitializeComponent();dinner=newDinner((int)dinnerNumericUpDown.Value);dinner.SetWineOption(dinnerWinerCheckBox.Checked);//人均饮料费用DisplayDinnerCost();//总费用}privatevoidDisplayDinnerCost(){decimalCost=dinner.CalculateCost();CostLabel.Text=Cost.ToString(“c”);}privatevoiddinnerNumericUpDown_ValueChanged(objectsender,EventArgse){dinner.NumberOfPeople=(int)dinnerNumericUpDown.Value;//设置用餐人数DisplayDinnerCost();//总费用}privatevoiddinnerMemberCheckBox_CheckedChanged(objectsender,EventArgse){dinner.customer.SetMemberOption(dinnerMemberCheckBox.Checked);//设置客户是否为会员DisplayDinnerCost();//总费用}privatevoiddinnerWinerCheckBox_CheckedChanged(objectsender,EventArgse){dinner.SetWineOption(dinnerWinerCheckBox.Checked);//设置是否饮用酒水DisplayDinnerCost();//总费用}privatevoidcancaBbutton_Click(objectsender,EventArgse){Close();}}}usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Threading.Tasks;usingSystem.Windows.Forms;namespaceSpiritKitchen{staticclassProgram{///<summary>///应用程序的主入口点。///</summary>[STAThread]staticvoidMain(){Application.EnableVisualStyles();Applica
