Enum.TryParse(TEnum) converts string to enumerated object

 

<Flags> Enum Colors As Integer
   None = 0
   Red = 1
   Green = 2
   Blue = 4
End Enum

Module Example
   Public Sub Main()
      Dim colorStrings() As String = {"0", "2", "8", "blue", "Blue", "Yellow"}
      For Each colorString As String In colorStrings
         Dim colorValue As Colors
         If [Enum].TryParse(colorString, colorValue) Then        
            If [Enum].IsDefined(GetType(Colors), colorValue) Or colorValue.ToString().Contains(",") Then 
               Console.WriteLine("Converted '{0}' to {1}.", colorString, colorValue.ToString())
            Else
               Console.WriteLine("{0} is not an underlying value of the Colors enumeration.", colorString)            
            End If                    
         Else
            Console.WriteLine("{0} is not a member of the Colors enumeration.", colorString)
         End If
      Next
   End Sub
End Module
