== 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<SomeType>)++`` 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<int>); // Noncompliant, always false
|
|
comparison = nullable.GetType() != typeof(Nullable<int>); // Noncompliant, always true
|
|
|
|
nullable = null;
|
|
comparison = nullable.GetType() != typeof(Nullable<int>); // Noncompliant, calling GetType on a null always throws an exception
