C# Interface without static typing

Is there way to do something along these lines?

interface Iface
{
  [anytype] Prop1 { get; }
  [anytype] Prop2 { get; }
}

class Class1 : Iface
{
  public string Prop1 { get; }
  public int Prop2 { get; }
}

class Class2 : Iface
{
  public int Prop1 { get; }
  public bool? Prop2 { get; }
}

I don't care about the type of the properties, I just need the properties to be available. This doesn't have to be implemented with an interface, just using that as an example.
