WPFMVVM实现ICommand与INotifyPropertyChanged接口

话不多说直接上代码

INotifyPropertyChanged实现代码

internal class NotifyBase : INotifyPropertyChanged
{
public event PropertyChangedEventHandler? PropertyChanged;

public void SetProperty<T>(ref T feild, T value, [CallerMemberName] string propName = "")
{
feild = value;
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propName));
}

}

ICommand实现代码

public class Command : ICommand
{
public event EventHandler? CanExecuteChanged;

public bool CanExecute(object? parameter) => true;

public void Execute(object? parameter)
{
DoExecute?.Invoke(parameter);
}
public Action<object> DoExecute { get; set; }

public Command(Action<object> doExecute)
{
DoExecute = doExecute;
}
}
