Sharing properties without inheritance

Question

I use the Unity engine, where the base class for almost all scripts should be obtained from MonoBehaviour. I created my own wrapper class, which derives from MonoBehaviour called CMonoBehaviour, which contains some of my helper functions, which I use almost everywhere. But now I am faced with the problem that SOMETIME I do not want to retrieve from MonoBehavuour, but ThirtPartyLibraryWrapperClass (a class that also derives from MonoBehaviour but also performs some additional functionality - just like my wrapper). Here is an example of what I want to archive.

edit: I forgot to mention that ThirtPartyLibraryWrapperClass is packaged in a dll, which means that I cannot change it in any way.

 // This is what I have
public class CMonoBehavour : MonoBehaviour
{
    public int SomeHelperProperty1 { get; private set; }
    public int SomeHelperProperty2 { get; private set; }
    public int SomeHelperProperty3 { get; private set; }
    public int SomeHelperProperty4 { get; private set; }
}

public class ThirtPartyLibraryWrapperClass : MonoBehaviour
{
    public int SomeHelperProperty5 { get; private set; }
    public int SomeHelperProperty6 { get; private set; }
}

// My problem :

public class ExampleUseage1 : CMonoBehavour
{
    // here I have to copypaste content of ThirtPartyLibraryWrapperClass because I cust cannot derive from two classes
}

public class ExampleUseage2 : ThirtPartyLibraryWrapperClass
{
    // here I have to copypaste content of CMonoBehavour because I cust cannot derive from two classes
}

CMonoBehavour (uh, CMonoBehaviour, i "" ) .

public interface CMonoBehaviour
{
    int SomeHelperProperty1 { get; }
    int SomeHelperProperty2 { get; }
    int SomeHelperProperty3 { get; }
    int SomeHelperProperty4 { get; }

        }

        private set  {
            a = value;
