Template Specialization Workaround

Question

C# does not support template specialization. Is there a workaround? I am interested in achieving something similar to the c++ code below.

Thank you

    class C
    {
    public:
        template< typename T > void f() {} // no parameter function
        template<> void f<double>() {} // no parameter function
    };

For those who don't read C++ on a regular basis but who might know a fair deal about C# features, can you explain *what* the C++ code achieves? — Damien_The_Unbeliever, Apr 28 '20 at 15:20
@Damien_The_Unbeliever This is just an example. The actual code is complex. I cannot think of a different example. — CFlat, Apr 28 '20 at 17:57

No, that's not possible, you have to use dynamic dispatching

public class C
{
    public int DoWork<T>()
    {
        if (typeof(T) == typeof(int))
            return DoWorkInt();

        return 13;
    }
    private int DoWorkInt() { return 42; }
}

C# does not support explicit specialization; that is, a custom implementation of a template for a specific type.
