Is anyone else having this issue.  I'm trying to pull all the email addresses in a particular role.  I'm able to successfully get everything but the email addresses.  Am I missing something?  Here's what I've got:

I confirmed that the Email property always comes up as Nothing in the UserRoleInfo object - the problem seems to be in the stored proceedure "GetUserRolesByUsername" which only includes all columns of the Rolls table and the calculated column "Fullname" from the Users table - either by bug or design.  Though its more inefficient, you could do a lookup on each user by objUser.UserID:

Dim rc As New Roles.RoleController
Dim uc As New DotNetNuke.Entities.Users.UserController
Dim objRoleList As ArrayList
objRoleList = rc.GetUsersInRole(PortalId, "Registered Users")
Dim sName As String = UserInfo.FirstName
Dim sEMail As String = UserInfo.Membership.Email
Dim rName As String
Dim rEMail As String
For Each objRoleInfo As DotNetNuke.Entities.Users.UserRoleInfo In objRoleList
      Dim objUser As Entities.Users.UserInfo = uc.GetUser(PortalId, objRoleInfo.UserID)
      rName = objUser.FullName
      rEMail = objUser.Membership.Email
Next

I would also suggest that your move setting the sender's name and Email outside of the loop.

Email is blank because the store proc "GetUserRolesByUsername" does not have field Email selected.  If you add the email column the store proc (see field in red), the email will have value in it.  However, this is equipvalent to CORE change.

Maybe you want to try the code below where LookupUserId = UserRoleInfo.UserID

Dim objUserController As New UserController

Dim objUserInfo As UserInfo = objUserController.GetUser(PortalId, LookupUserId)

Thanks guys!  Both solutions work just fine.  I went with imagemakers suggestion as not to modify the stored proc and to avoid overwrites.

Thanks again guys - I got some really good suggestions and was toying with that more than I want to admit!
