== Why is this an issue? Calling ``++GetType()++`` on a nullable object returns the underlying value type. Thus, comparing the returned ``++Type++`` object to ``++typeof(Nullable)++`` doesn't make sense. The comparison either throws an exception or the result can be known at compile time. === Noncompliant code example [source,csharp] ---- int? nullable = 42; bool comparison = nullable.GetType() == typeof(Nullable); // Noncompliant, always false comparison = nullable.GetType() != typeof(Nullable); // Noncompliant, always true nullable = null; comparison = nullable.GetType() != typeof(Nullable); // Noncompliant, calling GetType on a null always throws an exception ---- ifdef::env-github,rspecator-view[] ''' == Implementation Specification (visible only on this page) include::message.adoc[] include::highlighting.adoc[] ''' == Comments And Links (visible only on this page) include::comments-and-links.adoc[] endif::env-github,rspecator-view[]
