在Windows Presentation Foundation (WPF) 中，Model-View-ViewModel (MVVM) 是一种流行的软件设计模式，它促进了用户界面（UI）与业务逻辑的解耦。MVVM通过数据绑定和命令来实现这一目标，而`ICommand` 和 `INotifyPropertyChanged` 接口在其中扮演着关键角色。下面我们将深入探讨这两个接口以及它们在WPF MVVM中的应用。 `ICommand` 接口是WPF中用于实现命令行为的接口。它定义了两个方法：`Execute` 和 `CanExecute`。`Execute` 方法执行命令的实际操作，而`CanExecute` 则用于确定命令是否可以执行，这通常与当前UI状态或数据模型的状态有关。在MVVM模式下，ViewModel实现了`ICommand`，并将命令绑定到View的控件上，如按钮，使得当用户点击按钮时，ViewModel中的相应方法会被调用，执行相应的业务逻辑。例如，假设我们有一个保存数据的命令，ViewModel可以创建一个实现`ICommand`的类，并在`Execute`方法中执行保存操作。在View中，我们可以将这个命令绑定到按钮的`Command`属性上，使得每次点击按钮时都会触发ViewModel的保存操作。 `INotifyPropertyChanged` 是一个接口，它允许对象通知观察者其属性值的变化。在MVVM中，ViewModel通常会实现此接口，以便在模型的数据发生变化时，能够更新与之绑定的View。当ViewModel的某个属性值改变时，会触发`PropertyChanged`事件，View监听到这个事件后，会自动更新相关的UI元素。举个例子，假设我们有一个显示用户名的文本框，其Text属性绑定到ViewModel的`UserName`属性。当用户在文本框中输入新的用户名时，ViewModel的`UserName`属性需要触发`PropertyChanged`事件，这样View就能自动更新显示，反映新的用户名。在WPF_MVVMICommand这个示例项目中，我们可以预期它会包含以下几个部分： 1. Model层：包含业务对象和数据模型，可能不直接与UI交互。 2. ViewModel层：实现`ICommand`和`INotifyPropertyChanged`接口，处理业务逻辑，提供数据给View，并响应View的命令请求。 3. View层：XAML文件定义UI布局，通过数据绑定将UI元素与ViewModel的属性和命令关联起来。具体到文件名`WPF_MVVMICommand`，这可能是一个演示或教程项目，展示了如何在WPF中使用MVVM模式实现命令功能，特别是`ICommand`的实现和`INotifyPropertyChanged`接口的应用。通过分析和学习这个项目，开发者可以更好地理解如何在实际开发中运用这些概念和技术，提高WPF应用的可维护性和灵活性。 `ICommand`和`INotifyPropertyChanged`是MVVM模式中不可或缺的部分，它们分别负责命令的执行和数据的双向绑定，有效降低了UI与业务逻辑之间的耦合度，提高了代码的可测试性和复用性。在WPF_MVVMICommand这个例子中，开发者可以深入学习这两个接口的具体实现和使用场景，提升自己的WPF开发能力。
