InvalidCastException Error

I am trying to use an enumeration to limit the values an object can have. Anytime I try to assign a value using a string to the newly created object I get an casting exception error but when I use the numeric value it works fine. Can someone please help me solve this issue. The error and code are below.
Thanks

An unhandled exception of type 'System.InvalidCastException' occurred in microsoft.visualbasic.dll

Additional information: Cast from string "Access" to type 'Integer' is not valid.


Public Class DAL_Properties

Private Enum DataStoreTypes
SQLServer = 1

letsgetiton = 4

Private _connectionString As IDbConnection

Public Class DALTest

An enum is stored as an integer so if you want to convert a string to its enum value then you can use Enum.Parse.

VB Code:

_datastoreType = [Enum].Parse(GetType(DataStoreTypes), "Access")

Also you should declare your property types:

VB Code:

Public Property DatastoreType()[color=red][b] As DataStoreTypes[/b][/color]
Get
Return _datastoreType
End Get
Set(ByVal Value)
_datastoreType = Value
End Set
End Property
End Class
