C＃/ WPF：对的PropertyChanged视图模型中的所有属性？ [英] C#/WPF: PropertyChanged for all Properties in ViewModel?

问题描述

我有这样一个类：

public class PersonViewModel : ViewModelBase //Here is the INotifyPropertyChanged Stuff
{
    public PersonViewModel(Person person)
    {
        PersonEntity = person;
    }

    public Person PersonEntity { 
        get { return PersonEntity.Name; }
        private set { PersonEntity.Name = value; RaisePropertyChanged("PersonEntity");
    }

    public string Name { 
        get { return PersonEntity.Name; }
        set { PersonEntity.Name = value; RaisePropertyChanged("Name");
    } 
    public int Age{ 
        get { return PersonEntity.Age; }
        set { PersonEntity.Age= value; RaisePropertyChanged("Age");
    } 

    public void ChangePerson(Person newPerson)
    {
        //Some Validation..
        PersonEntity = newPerson;
    }

我的文本框绑定到名称和视图模型的时代。
。如果我更改视图模型的_person对象，我必须再次呼吁为每个属性一个RaisePropertyChanged还是有办法做到这一点全自动（在我的混凝土比如我有大约15属性..）？

My TextBoxes are bound to Name and Age of the ViewModel. If I change the _person object in the ViewModel, do I have to call for each Property a RaisePropertyChanged again or is there a way to do this automaticly (in my concret example I have about 15 Properties..)?

感谢您的帮助。

推荐答案

您可以指示所有属性都使用空或的String.Empty 的属性名称 PropertyChangedEventArgs 。这是在文档中提到的PropertyChanged 。

You can indicate all properties have changed by using null or string.Empty for the property name in PropertyChangedEventArgs. This is mentioned in the documentation for PropertyChanged.
