The following example shows the use of members of the GenericPrincipal class.
using System; using System.Security.Principal; class GenericPrincipalMembers { [STAThread] static void Main(string[] args) { // Retrieve a GenericPrincipal that is based on the current user's // WindowsIdentity. GenericPrincipal genericPrincipal = GetGenericPrincipal(); // Retrieve the generic identity of the GenericPrincipal object. GenericIdentity principalIdentity = (GenericIdentity)genericPrincipal.Identity; // Display the identity name and authentication type. if (principalIdentity.IsAuthenticated) { Console.WriteLine(principalIdentity.Name); Console.WriteLine("Type:"+principalIdentity.AuthenticationType); } // Verify that the generic principal has been assigned the // NetworkUser role. if (genericPrincipal.IsInRole("NetworkUser")) { Console.WriteLine("User belongs to the NetworkUser role."); } Console.WriteLine("The sample completed successfully; " + "press Enter to continue."); Console.ReadLine(); } // Create a generic principal based on values from the current // WindowsIdentity. private static GenericPrincipal GetGenericPrincipal() { // Use values from the current WindowsIdentity to construct // a set of GenericPrincipal roles. WindowsIdentity windowsIdentity = WindowsIdentity.GetCurrent(); string[] roles = new string[10]; if (windowsIdentity.IsAuthenticated) { // Add custom NetworkUser role. roles[0] = "NetworkUser"; } if (windowsIdentity.IsGuest) { // Add custom GuestUser role. roles[1] = "GuestUser"; } if (windowsIdentity.IsSystem) { // Add custom SystemUser role. roles[2] = "SystemUser"; } // Construct a GenericIdentity object based on the current Windows // identity name and authentication type. string authenticationType = windowsIdentity.AuthenticationType; string userName = windowsIdentity.Name; GenericIdentity genericIdentity = new GenericIdentity(userName, authenticationType); // Construct a GenericPrincipal object based on the generic identity // and custom roles for the user. GenericPrincipal genericPrincipal = new GenericPrincipal(genericIdentity, roles); return genericPrincipal; } }
