Static Code Analysis - The "Possible System.NullReferenceException" diagnostic should not be produced for CType

created 7 years ago

Please see following example (hint: CType != TryCast)

Visual Basic
Public Class Class1 Function Foo(value As Object) As Integer Dim result As Integer If (value IsNot Nothing) AndAlso (TypeOf value Is String) Then 'CRR0027 result = CType(value, String).Length End If Return result End Function End Class

CTyp e would produce a runtime exception if cast is not possible.
