I am trying to use GetUserRole method in my page. However there is an error message saying that  "Reference to a non shared member requires an object reference". What am i doing wrong. However it tells me correctly that there are 3 parameters (portalid, userid and roleid) required. Where do i need to instantiate it?

Thank you so much Brandon. That worked! However, I am facing this issue. I am trying to get the role info for the role "Registered User". Code looks something like this

Dim roleinfoObj As New DotNetNuke.Security.Roles.RoleInfo
Dim contoller1 As DotNetNuke.Security.Roles.RoleProvider
roleinfoObj = contoller1.GetRole(PortalId, "Registered Users")

         The error message is "controller1" needs to be be assigned a value before it can be used.  All i am trying to do is get the roleId for the role "Registered User". Please let me know if there is a simpler way or what i am doing wrong with the above code. Thanks in advance.

Try

Dim controller1 as New DotNetNuke.Security.Roles.RoleProvider

or

Dim controller1 as DotNetNuke.Security.Roles.RoleProvider = New DotNetNuke.Security.Roles.RoleProvider
