Optional Parameters like VB in C#

Hi all,
This may be a silly question, but:
Is there a way in C# to do a function call with an OPTIONAL argument like in VB?
For instance, in VB I can do this:
Public Function SubName(strName as string, optional strEmail as string = "") as Boolean
   SubName = False
    If strEmail <> "" then
      SubName = True
   End If
End Function
How can I do this in C#?

you need overloading:

Public bool SubName(strName as string, string  strEmail)
   SubName = (strEmail != String.empty)
End Function

Public bool SubName(strName as string)
   Return SubName(strName, String.Empty)
End Function
