Static Code Analysis - The "Possible System.NullReferenceException" diagnostic should take Null-conditional-operator within if-Operator into account

created 6 years ago

Please see following example (I know it looks stupid. But I have cases with complex classes where that applies.):

Visual Basic
Public Class Class1 Public Function Foo(value As String) As Integer If If(value?.Length, 0) = 0 Then Return -1 'CRR0027 (false positive) Return value.Length End Function Public Function Bar(value As String) As Integer If value Is Nothing Then Return -1 If value.Length = 0 Then Return -1 'No CRR0027 Return value.Length End Function End Class
