接下来写ViewModels
创建运单的ViewModel类
public class CreateExpressWindowViewModel: NotificationObject { private string province; public string Province { get { return province; } set { province = value; this.RaisePropertyChanged("Province"); } } private string city; public string City { get { return city; } set { city = value; this.RaisePropertyChanged("City"); } } private string area; public string Area { get { return area; } set { area = value; this.RaisePropertyChanged("Area"); } } private string street; public string Street { get { return street; } set { street = value; this.RaisePropertyChanged("Street"); } } private string username; public string Username { get { return username; } set { username = value; this.RaisePropertyChanged("Username"); } } private string phonenumber; public string Phonenumber { get { return phonenumber; } set { phonenumber = value; this.RaisePropertyChanged("Phonenumber"); } } private string createtime; public string Createtime { get { return createtime; } set { createtime = value; this.RaisePropertyChanged("Createtime"); } } public DelegateCommand CreateExpressCommand { get; set; } public CreateExpressWindowViewModel() { Createtime = DateTime.Now.ToShortDateString(); CreateExpressCommand = new DelegateCommand(new Action(InsertExpress)); } private void InsertExpress() { //Random rd = new Random(); //int num = rd.Next(10000000, 99999999); InsertExpressService insertExpressService = new InsertExpressService(); Express express = new Express(); insertExpressService.InsertExpress(Province,City,Area,Street,Username,Phonenumber,Createtime); MessageBox.Show("成功下单！"); ExpressWindow expressWindow = new ExpressWindow(); ReadExpressWindow readExpressWindow = new ReadExpressWindow(); readExpressWindow.Show(); expressWindow.Close(); } }
public class GetExpressWindow : NotificationObject { private string province; public string Province { get { return province; } set { province = value; this.RaisePropertyChanged("Province"); } } private string city; public string City { get { return city; } set { city = value; this.RaisePropertyChanged("City"); } } private string area; public string Area { get { return area; } set { area = value; this.RaisePropertyChanged("Area"); } } private string street; public string Street { get { return street; } set { street = value; this.RaisePropertyChanged("Street"); } } private string username; public string Username { get { return username; } set { username = value; this.RaisePropertyChanged("Username"); } } private string phonenumber; public string Phonenumber { get { return phonenumber; } set { phonenumber = value; this.RaisePropertyChanged("Phonenumber"); } } private string createtime; public string Createtime { get { return createtime; } set { createtime = value; this.RaisePropertyChanged("Createtime"); } } public DelegateCommand GetExpressCommand { get; set; } public GetExpressWindow() { GetExpressCommand = new DelegateCommand(new Action(GetExpress)); } private void GetExpress() { GetExpressService getExpressService = new GetExpressService(); Express express = new Express(); express = getExpressService.GetExpressData(); Province = express.Province; City = express.City; Area = express.Area; Street = express.Street; Username = express.UserName; Phonenumber = express.PhoneNumber; Createtime = express.CteateTime; } }
public class RegisteredWindowViewModel : NotificationObject { private string userAccount; public string UserAccount { get { return userAccount; } set { userAccount = value; this.RaisePropertyChanged("UserAccount"); } } private string password; public string Password { get { return password; } set { password = value; this.RaisePropertyChanged("Password"); } } public DelegateCommand InsertCommand { get; set; } public RegisteredWindowViewModel() { InsertCommand = new DelegateCommand(new Action(InsertUserData)); } private void InsertUserData() { InsertRegisteredService insertRegisteredService = new InsertRegisteredService(); User user = new User(); user.UserAccount = UserAccount; user.Password = Password; user = insertRegisteredService.InsertUser(UserAccount, Password); MessageBox.Show("注册成功！"); } }
public class UserViewModel: NotificationObject { ////// 判断登录用户是否存在 /// private bool exist; public bool Exist { get { return exist; } set { exist = value; this.RaisePropertyChanged("Exist"); } } }
public class UserWindowViewModel : NotificationObject { //var logger = NLog.LogManager.GetCurrentClassLogger(); //logger.Info("Hello World"); //var a = LogManager.GetCurrentClassLogger(); private string username; public string Username { get { return username; } set { username = value; this.RaisePropertyChanged("Username"); } } private string userpassword; public string Userpassword { get { return userpassword; } set { userpassword = value; this.RaisePropertyChanged("Userpassword"); } } public DelegateCommand GetCommand { get; set; } public UserWindowViewModel() { GetCommand = new DelegateCommand(new Action(GetUser)); } private void GetUser() { GetUserService getUserServicelist = new GetUserService(); Listuserslist = getUserServicelist.GetAllUser(); List usernamecount = userslist.Where(x=>x.UserAccount==Username).ToList(); List passwordcount = userslist.Where(x=>x.Password==Userpassword).ToList(); ///方法二 for (int i = 0; i < usernamecount.Count; i++) { if (usernamecount[i].UserAccount==Username&&usernamecount[i].Password==Userpassword) { MessageBox.Show("登录成功！"); ExpressWindow expressWindow = new ExpressWindow(); expressWindow.ShowDialog(); return; } else { MessageBox.Show("账号不存在或密码错误！"); return; } } ///方法一 //if (usernamecount.Count > 0 && passwordcount.Count > 0) //{ // MessageBox.Show("登录成功！"); // return; //} //else //{ // MessageBox.Show("登录失败！"); // return; //} } }
以上分别为创建运单，查看运单，以及注册，以及登录的ViewModels，作为Views和Models之间的连接器
