If the nature of the issues helps you to do some rewriting to maneuver the constraint so it's declared on method level as opposed to course amount - such as by using a general public manufacturing unit course + implementation variety with internal constructor - then it gets probable to "constrain to null" with this particular clever workaround:
Be aware that if the class declared various parameterized kinds, it would not be seriously more challenging : class Info int discovered; Course hits; Checklist record;

Here is what I have now. Having said that, it's going to move again a 0 if a numeric benefit is invalid, Which sadly is a legitimate worth in my situations. Can any person enable me out? Many thanks!
I love to start with a class like this class settings community int X get;established; community string Y get; established; // repeat as vital
1 Static constructor placing a flag that throws an exception in the normal constructor is a good idea. Until it is a generic strategy, wherein circumstance there is not any constructor.
Consider developing a wrapper form that provides this. It'd be similar to how Nullable is carried out, and has the additional advantage of enabling a non-conclude-of-stream null worth to become transmitted, should that be useful.
Academically I read more do understand the distinction, but It might be an incredibly special scenario exactly where the distinction matters. (Envision a perform of generic nullable sort, wherever the return of "null" is used as a Unique marker, e.g. as some kind of mistake marker)

If you would like a parameterless constructor, you will not get the nicety of overloading, however you can still do some thing such as this:
You could potentially always produce an intermediate class/interface that will satisfy the generic sort you are attempting to specify. By way of example, if Foo was an interface, you could develop the following interface as part of your check class.
