我写了一篇文章来帮助你(https://msdn.microsoft.com/magazine/mt736453)。你可以使用SolSoft。DataBinding NuGet包。然后你可以这样写代码:

public class TestViewModel : IRaisePropertyChanged
{
  public TestViewModel()
  {
    this.m_nameProperty = new NotifyProperty<string>(this, nameof(Name), null);
  }

  private readonly NotifyProperty<string> m_nameProperty;
  public string Name
  {
    get
    {
      return m_nameProperty.Value;
    }
    set
    {
      m_nameProperty.SetValue(value);
    }
  }

  // Plus implement IRaisePropertyChanged (or extend BaseViewModel)
}

好处:

基类是可选的 没有对每个“设定值”进行反思 可以具有依赖于其他属性的属性，并且它们都自动引发适当的事件(本文有一个这样的示例)

如果你在。net 4.5中使用动态，你不需要担心INotifyPropertyChanged。

dynamic obj = new ExpandoObject();
obj.Name = "John";

如果Name被绑定到某个控件，它就可以正常工作。

=>这里我的解决方案具有以下特征

 public ResourceStatus Status
 {
     get { return _status; }
     set
     {
         _status = value;
         Notify(Npcea.Status,Npcea.Comments);
     }
 }

没有refelction 短的符号 业务代码中没有神奇的字符串 PropertyChangedEventArgs在应用程序中的可重用性 在一条语句中通知多个属性的可能性

我实际上还没有机会尝试这个自己，但下次我设置一个大需求的INotifyPropertyChanged项目，我打算写一个Postsharp属性，将在编译时注入代码。喜欢的东西:

[NotifiesChange]
public string FirstName { get; set; }

将成为:

private string _firstName;

public string FirstName
{
   get { return _firstname; }
   set
   {
      if (_firstname != value)
      {
          _firstname = value;
          OnPropertyChanged("FirstName")
      }
   }
}

我不确定这在实践中是否有效，我需要坐下来尝试一下，但我不明白为什么不。我可能需要让它接受一些参数的情况下，超过一个OnPropertyChanged需要被触发(如果，例如，我有一个FullName属性在上面的类)

目前我在Resharper使用一个自定义模板，但即使这样，我也厌倦了我所有的属性太长。

啊，一个快速的谷歌搜索(我应该在写这篇文章之前做的)显示至少有一个人在这里之前做过类似的事情。跟我想的不完全一样，但也足以证明这个理论是正确的。

Prism 5实现:

public abstract class BindableBase : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual bool SetProperty<T>(ref T storage,
                                          T value,
                                          [CallerMemberName] string propertyName = null)
    {
        if (object.Equals(storage, value)) return false;

        storage = value;
        this.OnPropertyChanged(propertyName);

        return true;
    }

    protected void OnPropertyChanged(string propertyName)
    {
        var eventHandler = this.PropertyChanged;
        if (eventHandler != null)
        {
            eventHandler(this, new PropertyChangedEventArgs(propertyName));
        }
    }

    protected void OnPropertyChanged<T>(Expression<Func<T>> propertyExpression)
    {
        var propertyName = PropertySupport.ExtractPropertyName(propertyExpression);
        this.OnPropertyChanged(propertyName);
    }
}

public static class PropertySupport
{
    public static string ExtractPropertyName<T>(Expression<Func<T>> propertyExpression)
    {
        if (propertyExpression == null)
        {
            throw new ArgumentNullException("propertyExpression");
        }

        var memberExpression = propertyExpression.Body as MemberExpression;
        if (memberExpression == null)
        {
            throw new ArgumentException("The expression is not a member access expression.", "propertyExpression");
        }

        var property = memberExpression.Member as PropertyInfo;
        if (property == null)
        {
            throw new ArgumentException("The member access expression does not access a property.", "propertyExpression");
        }

        var getMethod = property.GetMethod;
        if (getMethod.IsStatic)
        {
            throw new ArgumentException("The referenced property is a static property.", "propertyExpression");
        }

        return memberExpression.Member.Name;
    }
}

让我介绍一下我自己的方法，叫做Yappi。 它属于运行时代理|派生类生成器，向现有对象或类型添加新功能，如种姓项目的动态代理。

它允许在基类中实现INotifyPropertyChanged一次，然后以以下风格声明派生类，仍然支持INotifyPropertyChanged用于新属性:

public class Animal:Concept
{
    protected Animal(){}
    public virtual string Name { get; set; }
    public virtual int Age { get; set; }
}

派生类或代理构造的复杂性可以隐藏在下面这行代码后面:

var animal = Concept.Create<Animal>.New();

所有的INotifyPropertyChanged实现工作可以像这样完成:

public class Concept:INotifyPropertyChanged
{
    //Hide constructor
    protected Concept(){}

    public static class Create<TConcept> where TConcept:Concept
    {
        //Construct derived Type calling PropertyProxy.ConstructType
        public static readonly Type Type = PropertyProxy.ConstructType<TConcept, Implementation<TConcept>>(new Type[0], true);
        //Create constructing delegate calling Constructor.Compile
        public static Func<TConcept> New = Constructor.Compile<Func<TConcept>>(Type);
    }


    public event PropertyChangedEventHandler PropertyChanged;

    protected void OnPropertyChanged(PropertyChangedEventArgs eventArgs)
    {
        var caller = PropertyChanged;
        if(caller!=null)
        {
            caller(this, eventArgs);
        }
    }

    //define implementation
    public class Implementation<TConcept> : DefaultImplementation<TConcept> where TConcept:Concept
    {
        public override Func<TBaseType, TResult> OverrideGetter<TBaseType, TDeclaringType, TConstructedType, TResult>(PropertyInfo property)
        {
            return PropertyImplementation<TBaseType, TDeclaringType>.GetGetter<TResult>(property.Name);
        }
        /// <summary>
        /// Overriding property setter implementation.
        /// </summary>
        /// <typeparam name="TBaseType">Base type for implementation. TBaseType must be TConcept, and inherits all its constraints. Also TBaseType is TDeclaringType.</typeparam>
        /// <typeparam name="TDeclaringType">Type, declaring property.</typeparam>
        /// <typeparam name="TConstructedType">Constructed type. TConstructedType is TDeclaringType and TBaseType.</typeparam>
        /// <typeparam name="TResult">Type of property.</typeparam>
        /// <param name="property">PropertyInfo of property.</param>
        /// <returns>Delegate, corresponding to property setter implementation.</returns>
        public override Action<TBaseType, TResult> OverrideSetter<TBaseType, TDeclaringType, TConstructedType, TResult>(PropertyInfo property)
        {
            //This code called once for each declared property on derived type's initialization.
            //EventArgs instance is shared between all events for each concrete property.
            var eventArgs = new PropertyChangedEventArgs(property.Name);
            //get delegates for base calls.
            Action<TBaseType, TResult> setter = PropertyImplementation<TBaseType, TDeclaringType>.GetSetter<TResult>(property.Name);
            Func<TBaseType, TResult> getter = PropertyImplementation<TBaseType, TDeclaringType>.GetGetter<TResult>(property.Name);

            var comparer = EqualityComparer<TResult>.Default;

            return (pthis, value) =>
            {//This code executes each time property setter is called.
                if (comparer.Equals(value, getter(pthis))) return;
                //base. call
                setter(pthis, value);
                //Directly accessing Concept's protected method.
                pthis.OnPropertyChanged(eventArgs);
            };
        }
    }
}

它对于重构是完全安全的，在类型构造后不使用反射，并且足够快。
