Question

I’m reflecting a property ‘Blah’ its Type is ICollection

    public ICollection<string> Blah { get; set; }

    private void button1_Click(object sender, RoutedEventArgs e)
    {
        var pi = GetType().GetProperty("Blah");
        MessageBox.Show(pi.PropertyType.ToString());
    }

This gives me (as you’d expect!) ICollection<string> …

But really I want to get the collection type i.e. ICollection (rather than ICollection<string>) – does anyone know how i’d do this please?

You’re looking for the GetGenericTypeDefinition method:

MessageBox.Show(pi.PropertyType.GetGenericTypeDefinition().ToString());
