Question

I am building a User Management section to a website CMS.

The user has a list of users and then clicks the edit button, the system then stored the UserId in a session and goes to the editUser.aspx page which will show the users details.

To get the users details I need to convert the UserId session to a Guid so i can get user details.

I keep getting error message:

System.InvalidCastException: Specified cast is not valid.

Dim selectedUserId As Guid = CType(Session("strUserId"), Guid)
Dim mu As MembershipUser = Membership.GetUser(selectedUserId)

Does anyone know if this is possible?

Thanks in advance.

Use Guid.Parse() instead. You are storing a string, so must convert from a string back to a Guid.
