Property Value

Type: System.String
The name of the role provider that is used to get the user's roles.

You use the ProviderName property to set the role provider during the SelectingProvider event.

The following example shows an event handler for the SelectingProvider event. The event handler uses the SelectingProviderEventArgs object to check the user name and to set the role provider to use. The event handler is bound to the SelectingProvider event in the Application_Start method of the Global.asax file.

void Application_Start(object sender, EventArgs e) 
{
    System.Web.ApplicationServices.RoleService.SelectingProvider += 
        new EventHandler<System.Web.ApplicationServices.SelectingProviderEventArgs>(RoleService_SelectingProvider);
}

void RoleService_SelectingProvider
    (object sender, System.Web.ApplicationServices.SelectingProviderEventArgs e)
{
    if (e.User.Identity.Name.IndexOf("@example.com") > 0)
    {
        e.ProviderName = "EmployeeRoleProvider";
    }
    else
    {
        e.ProviderName = "CustomerRoleProvider";
    }
}
