public class ThirdPartyClass1 {
    public string Name {
        get {
            return "ThirdPartyClass1";

    }

    public void DoThirdPartyStuff() {
        Console.WriteLine("ThirdPartyClass1 is doing its thing.");
    }
}

public interface IThirdPartyClassWrapper {

    public void DoThirdPartyStuff();
}

public class ThirdPartyClassWrapper1 : IThirdPartyClassWrapper {

    ThirdPartyClass1 _thirdParty;

    public string Name {
        get { return _thirdParty.Name; }
    }

    public void DoThirdPartyStuff() {
        _thirdParty.DoThirdPartyStuff();
    }
}

...and the same for ThirdPartyClass2, then you use the wrapper interface in all your methods.
