What is the right way, to get a service name inside a method?

Question

I have the following code inside a Xamarin Visual Studio .Net app:

[Service(Name = "MyServiceName")]
internal class MyService : Service
{
    public MyService()
    {
        var thisName = nameof(this);
    }

thisName should be MyServiceName. But this fails.

What is the right way, to get MyServiceName inside a method?

I want to get the name of the Service, not of a property inside the Service class.
