Translate C# code to VB.net

Question

I previously worked on a C# project but now I'm working with Visual Basic and what I want to do is simply translate the C# code to Visual Basic and it's going fine except for one piece of code of C# that I have no idea how to translate to VB

The C# code is:

private void ReadInput(Animal animal)
{
    // Mammal is a class that inherits from the Animal class
    Mammal mammal = animal as Mammal; //<<----How to translate this code?
    if (mammal != null)
    {
        mammal.Teeth = ReadTeeth();
    }
}

I'm not really sure how to translate animal as Mammal to Visual Basic.

Use TryCast to treat animal as mammal

 Dim mammal As Mammal = TryCast(animal, Mammal)

@John.P, if it worked then you should click the check mark. Also note that in cases where `TryCast` fails, mammal will be `Nothing`, so you should check. – Ňɏssa Pøngjǣrdenlarp Jul 26 '15 at 15:07

The missing piece in your conversion is TryCast(animal, Mammal)

There are a lot of code converters online that can help you to answer questions of the type "how can I translate code x from language y to language z?":

and more ...

Note: Some converters only work properly if you embed your code snippet into a class. For your specific example, some of them had trouble with the code comments. After removing them, everything went smooth.

They will yield something like this (comments removed):

Private Sub ReadInput(animal As Animal)
    Dim mammal As Mammal = TryCast(animal, Mammal)
    If mammal IsNot Nothing Then
        mammal.Teeth = ReadTeeth()
    End If
End Sub
