Question

Imagine I have this class:

Class Foo
{
    public Bar b1 { get; set; }
    public Bar b2 { get; set; }
    public Bar b3 { get; set; }

    public void UpdateBarsMyProp(bool value)
    {
        // ????
    }
}

Class Bar
{
    public bool MyProp { get; set; }

    public bool UpdateMyProp(bool value)
    {
        this.MyProp = value;
    }
}

What’s the best way to update the property MyProp in b1, b2 and b3?

Generics?

Delegates?

EDIT:

Just to add more information about my specific situation:

I’m creating a virtual keyboard and I’m using WPF MVVM so I have:

A KeyBoard ViewModel which contains several Key ViewModels, I can’t store them in a List because im my View (xaml file) I need to bind each key information to a specific ViewModel.

Now, when the user presses the virtual shift button, I need my Keyboard ViewModel object to update the display char in every Key ViewModel.

You could put your properties in a List<Bar> (or an array if you prefer…) and iterate over it.

So:

public Bar b1 { get; set; }
public Bar b2 { get; set; }
public Bar b3 { get; set; }
// other Bar props...

private List<Bar> barsList = new List<Bar>(){ b1, b2, b3, ... };

public void UpdateBarsMyProp(bool value)
{
    foreach(Bar bar in barsList)
    {
        bar.MyProp = value;
    }
}
