WPF MVVM模式不用Prism

上一个例子使用了Prism。这个例子不用Prism。用自己封装的库LiuxhCSDLL，其实也差不多。

一、程序结构

二、界面代码以及界面效果

 <Window x:Class="WPFMVVMExample.MainWindow"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         Title="MainWindow" Height="350" Width="525">
     <Grid>
         <Label Content="学号" Height="28" HorizontalAlignment="Left" Margin="54,23,0,0" Name="labelStudentId" VerticalAlignment="Top" />
         <TextBox Text="{Binding Student.StudentId}" IsReadOnly="True" Height="23" HorizontalAlignment="Right" Margin="0,27,289,0" Name="textBoxStudentId" VerticalAlignment="Top" Width="120" />
         <Label Content="姓名" Height="28" HorizontalAlignment="Left" Margin="54,61,0,0" Name="labelStudentName" VerticalAlignment="Top" />
         <TextBox Text="{Binding Student.StudentName}" IsReadOnly="True" Height="23" HorizontalAlignment="Left" Margin="94,65,0,0" Name="textBoxStudentName" VerticalAlignment="Top" Width="120" />
         <Label Content="年龄" Height="28" HorizontalAlignment="Left" Margin="54,94,0,0" Name="labelStudentAge" VerticalAlignment="Top" />
         <TextBox Text="{Binding Student.StudentAge}" IsReadOnly="True" Height="23" HorizontalAlignment="Left" Margin="94,99,0,0" Name="textBoxStudentAge" VerticalAlignment="Top" Width="120" />
         <Label Content="Email" Height="28" HorizontalAlignment="Left" Margin="50,138,0,0" Name="labelStudentEmail" VerticalAlignment="Top" />
         <TextBox Text="{Binding Student.StudentEmail}" IsReadOnly="True" Height="23" HorizontalAlignment="Left" Margin="94,141,0,0" Name="textBoxStudentEmail" VerticalAlignment="Top" Width="120" />
         <Label Content="性别" Height="28" HorizontalAlignment="Left" Margin="57,176,0,0" Name="labelStudentSex" VerticalAlignment="Top" />
         <TextBox Text="{Binding Student.StudentSex}" IsReadOnly="True" Height="23" HorizontalAlignment="Left" Margin="94,180,0,0" Name="textBoxStudentSex" VerticalAlignment="Top" Width="120" />
         <Button Command="{Binding ShowCommand}" Content="显示" Height="23" HorizontalAlignment="Left" Margin="345,27,0,0" Name="buttonShow" VerticalAlignment="Top" Width="75" />
     </Grid>
 </Window>

三、抽象出Model

 public class StudentModel
     {
         #region --原有的实现--
         //public event PropertyChangedEventHandler PropertyChanged;
         //public void NotifyPropertyChanged(string propertyName)
         //{
         //    if (PropertyChanged != null)
         //    {
         //        PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
         //    }
         //}

         //private int studentId;

         //public int StudentId
         //{
         //    get { return studentId; }
         //    set { studentId = value; NotifyPropertyChanged("StudentId"); }
         //}

         //private string studentName;

         //public string StudentName
         //{
         //    get { return studentName; }
         //    set { studentName = value; NotifyPropertyChanged("StudentName"); }
         //}

         //private int studentAge;

         //public int StudentAge
         //{
         //    get { return studentAge; }
         //    set { studentAge = value; NotifyPropertyChanged("StudentAge"); }
         //}

         //private string studentEmail;

         //public string StudentEmail
         //{
         //    get { return studentEmail; }
         //    set { studentEmail = value; NotifyPropertyChanged("StudentEmail"); }
         //}

         //private string studentSex;

         //public string StudentSex
         //{
         //    get { return studentSex; }
         //    set { studentSex = value; NotifyPropertyChanged("StudentSex"); }
         //}
         #endregion

         #region --新的实现--
         public int StudentId { get; set; }
         public string  StudentName { get; set; }
         public int StudentAge { get; set; }

         public string StudentEmail { get; set; }
         public string StudentSex { get; set; }
         #endregion
     }

四、ViewModel

 public class StudentViewModel:INotifyPropertyChanged
     {

         public event PropertyChangedEventHandler PropertyChanged;
         public void NotifyPropertyChanged(string propertyName)
         {
             if (PropertyChanged != null)
             {
                 PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
             }
         }

         public DelegateCommand ShowCommand { get; set; }
         public StudentViewModel()
         {
             ShowCommand = new DelegateCommand();
             ShowCommand.ExecuteCommand = new Action<object>(ShowStudentData);
         }

         //public StudentModel Student { get; set; }
         private StudentModel student;

         public StudentModel Student
         {
             get { return student; }
             set { student = value;NotifyPropertyChanged("Student"); }
         }

         private StudentModel StudentTemp;

         public void ShowStudentData(object obj)
         {
             StudentTemp = new StudentModel();
             Student = new StudentModel();

             StudentTemp.StudentId = ;
             StudentTemp.StudentName = "tiana";
             StudentTemp.StudentAge = ;
             StudentTemp.StudentEmail = "123@qq.com";
             StudentTemp.StudentSex = "大帅哥";

             Student = StudentTemp;
         }
     }

注：这个程序要引入自己封装的库，LiuxhCSDLL,目前这个库还不够通用，等水平提高了再来把它优化成通用的。
