Return object between screens - C #

I have a question about returning an object from a B canvas to an A canvas, for example.

I use the form below, hiding the ShowDialog of the base class, making the "new ShowDialog" return what I need. Here is a code example of the screen class that will return the object:

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        //trato meu objeto
        Close();
    }

    public new tipo_meu_objeto ShowDialog()
    {
        base.ShowDialog();
        return meu_objeto;
    }

I also know, through other questions already asked here, that there are other ways, such as using the created screen instance and accessing the variable through it.

My question is: What I exemplified is considered a good way to solve this? If not, what would be the best way to handle this?

Thank you in advance.

The best way to solve your problem would be to add a new property in your class that is called, and depending on DialogResult informed, whether or not there is content. Example:

public class JanelaDialogo : Window
{
    public object Resultado { get; private set; }

    private void OnClick_Sucesso(object sender, RoutedEventArgs e)
    {
        // este será o valor de retorno do método ShowDialog()
        DialogResult = true;

        Resultado = "Sucesso";

        Close();
    }    
}

Usage:

private void OnDialogo(object sender, RoutedEventArgs e)
{
    var win = new JanelaDialogo();

    if (win.ShowDialog() == true)
    {
        var resultado = win.Resultado;
    }
}
