Is it possible to have an arbitrary number of type arguments for an abstract method?

I have an abstract class, and I want to let the derived class define not only the value type, but let them define how many value types they have. Then I want to require them to have getters/setters for each type:

public abstract class A<T1, T2, ..., TN>
{
    // Getters
    public abstract T1 GetValue();
    public abstract T2 GetValue();
    ...
    public abstract TN GetValue();
    // Setters
    public abstract void SetValue(T1 newVal);
    public abstract void SetValue(T2 newVal);
    ...
    public abstract void SetValue(TN newVal);
}

Then the classes that derive from A can have as many values as they want, as long as they provide access to them. Is this possible in c#? Or something similar to it?

No. They must be explicitly defined because the compiler has to figure out what to do with the types to build into the assembly.

You could obtain a similar effect via a code generator.
