This overload of the RolePrincipal constructor creates a new RolePrincipal object and initializes its property values. Cached role information is not read from the cookie identified by the CookieName property. The ProviderName property is set to the Name of the default role provider.
For information on enabling role management, see the Roles class.
The following code example creates a new RolePrincipal object. If CacheRolesInCookie is true, the example creates the RolePrincipal with cookie information from the cookie identified by the CookieName property.
Dim r As RolePrincipal If Roles.CacheRolesInCookie Then Dim roleCookie As String = "" Dim cookie As HttpCookie = HttpContext.Current.Request.Cookies(Roles.CookieName) If Not cookie Is Nothing Then roleCookie = cookie.Value r = New RolePrincipal(User.Identity, roleCookie) Else r = new RolePrincipal(User.Identity) End If
