C# WPF数据绑定模板化操作的完整步骤_C#教程

 public class NotifyPropertyObject : INotifyPropertyChanged
  {
         public event PropertyChangedEventHandler PropertyChanged;
         public void RaisePropertyChanged(string propertyName)
         {
             if (PropertyChanged != null)
             {
                 PropertyChanged.Invoke(this, new PropertyChangedEventArgs(propertyName));
            }
         }
}
 
 private MainWindowVM vm = new MainWindowVM();             //重点
 public MainWindow()
 {                  
      InitializeComponent();
      this.DataContext = vm;//重点
 }

 public class MainWindowVM : NotifyPropertyObject
 {
     private double _dmsL0;   //中央子午线经度
         public double dmsL0
         {
             get { return _dmsL0; }
             set 
             {
                 _dmsL0 = value;
                 RaisePropertyChanged("dmsL0");
             }
         }
 }
 
 public class AzimuthWindowVM : NotifyPropertyObject
 {
     private string azName = "A001->B004的坐标方位角";
         public string AzName
         {
             get { return azName; }
             set 
             { 
                 azName = value;
                 RaisePropertyChanged("AzName"); 
             }
         }
 }

public class Ellipsoid : NotifyPropertyObject
 {
         private double _a; //长半轴
         public double a 
         {
             get => _a;
             set 
             {
                 _a = value;
                 if (_a > 0 && _f > 0) 
                 {
                     Init(a, f);
                 }
                 
                 RaisePropertyChanged("a");
             }
         }
 }

 1、<TextBox Grid.Column="2" VerticalAlignment="Center" Text="{Binding CurrentEllipsoid.a}"    IsEnabled="{Binding CurrentEllipsoid.IsCustomEllopsoid}"/>
 2、<ComboBox VerticalAlignment="Center" ItemsSource="{Binding EllipsoidList}"
    SelectedItem="{Binding CurrentEllipsoid}"/>
 3、Title="{Binding Title}"  注意：标题也可绑定
