How can u use it or write a similar method in older

Answer 1

@Rob, thank you so much, but the static member access could be for the non-static class members too.

public static class TestExtension {
    public static String nameof(this Expression> accessor)
    {
        return nameof(accessor.Body);
    }
}
class MyClass {
    public Guid MyOtherField;
}
TestExtension.nameof(o=>o.MyOtherField);

and the good news is the Class won't be instantiated. It is useful to access domain layer DTOs.
