Static Code Analysis - The "Possible System.NullReferenceException" diagnostic should take generic classes with constraints and reserved words into account

created 6 years ago (modified 6 years ago)

A little strange behavior, see following:

Visual Basic
Public Class Constraint Public Property Prop As Integer End Class Public Class Class1(Of T As Constraint) Public Function Foo([alias] As T) As Boolean If [alias] Is Nothing Then Return False 'CRR0027 Return [alias].GetHashCode <> 0 End Function Public Function Bar(value As T) As Boolean If value Is Nothing Then Return False 'No CRR0027 Return value.GetHashCode <> 0 End Function End Class Public Class Class2(Of T) Public Function Foo([alias] As T) As Boolean If [alias] Is Nothing Then Return False 'No CRR0027 Return [alias].GetHashCode <> 0 End Function End Class
