Cannot cast single custom listview row to its list's type

Hello,

I have this problem with a Custom listview adapter.

I cannot get the object that the adapter refers to because the compiler will not allow me to cast it to its type.

In Java I do so:

ModelloAttivita thisAttivita = (ModelloAttivita) (listAttivita.getItemAtPosition(selectedIndex)); // where listAttivita is a collection of ModelloAttivita

The C# code:

void listAttivita_ItemClick(object sender, AdapterView.ItemClickEventArgs e) { m_SelectedIndex = e.Position; object thisAttivita = listAttivita.GetItemAtPosition (e.Position); Console.WriteLine (thisAttivita); Toast toast = Toast.MakeText (this, "Selected: "+m_SelectedIndex+ " with Id: "+ thisAttivita.ToString(), ToastLength.Short); toast.Show (); } }

thisAttivita is of type ModelAttivita but, if I try to replace "object thisAttivita" with

ModelloAttivita thisAttivita = listAttivita.GetItemAtPosition (e.Position), I get the error "Cannot implicity convert Java.Lang.Object" to "TestDebug.ModelloAttivita"

The same happens with

ModelloAttivita thisAttivita = (ModelloAttivita) listAttivita.GetItemAtPosition (e.Position);

and

ModelloAttivita thisAttivita = (ModelloAttivita) listAttivita.GetItemAtPosition (e.Position); as ModelloAttivita;

How to obtain the object type corresponding to the row that was selected?

Thanks!
