I have multiple classes that have similar implementation for different named methods:

class MyClassX
{
   public int MyClassXIntMethod(){}
   public string MyClassXStringMethod(){}
}

class MyClassY
{
   public int MyClassYIntMethod(){}
   public string MyClassYStringMethod(){}
}

the methods inside the classes have similar implementation but because the method's names are different (due to 3rd party constraints) i cannot use inheritance.

I'm looking for an elegant solution that would be better than implementing the same functionality over and over again.
