有没有一个很好的强类型的方式来做C#中的PropertyChanged事件？

没有/ infoof等的名字;这是很多的讨论,但它是什么.

有一种方法可以使用.NET 3.5中的lambda表达式(并解析表达式树),但实际上它不值得开销.现在,我只是坚持使用字符串(单元测试,如果你决定不打破它).

using System;
using System.ComponentModel;
using System.Linq.Expressions;
using System.Reflection;
class Program : INotifyPropertyChanged {
    public event PropertyChangedEventHandler PropertyChanged;
    static void Main() {
        var p = new Program();
        p.PropertyChanged += (s,a) => Console.WriteLine(a.PropertyName);
        p.Name = "abc";
    }
    protected void OnPropertyChanged<T>(Expression<Func<Program,T>> property) {
        MemberExpression me = property.Body as MemberExpression;
        if (me == null || me.Expression != property.Parameters[0]
              || me.Member.MemberType != MemberTypes.Property) {
            throw new InvalidOperationException(
                "Now tell me about the property");
        }
        var handler = PropertyChanged;
        if (handler != null) handler(this,new PropertyChangedEventArgs(me.Member.Name));
    }
    string name;
    public string Name {
        get{return name;}
        set {
            name = value;
            OnPropertyChanged(p=>p.Name);
        }
    }
}
