C# – How RaisePropertyChanged works in MVVM light

MVVM light provides an easy way of the strong typed RaisePropertyChanged with lambda. The following code shows how this can find the correct string for member of ViewModel.

public void RaisePropertyChanged<T>(Expression<Func<T>> property)
{
    PropertyChanged(this, new PropertyChangedEventArgs(property.GetMemberInfo().Name);
}

so you can use the following code safely.

public class ViewModel : ViewModelBase
{
    private string _name;

    public string ProductName;
    { get { return _name; }
    {
      set
      {
          _name = value;
          RasePropertyChanged(() => ProductName);
      }
    }
}
