siteidentity.cs

基于角色的用户验证. 这个程序重点写了四个pages以实现这些功能：增加用户

using System;
using System.Data;
using System.Data.SqlClient;

namespace RolesBasedAthentication
{
	public class SiteIdentity: System.Security.Principal.IIdentity
	{
		private int userID;
		private string fullName;
		private string email;
		private string password;
		
		public SiteIdentity( string email )
		{
			User user = new User(email);

			this.userID = user.UserID;
			this.fullName = user.FullName;
			this.email = user.Email;
			this.password = user.Password;
		}

		public SiteIdentity( int userID )
		{
			User user = new User(userID);

			this.userID = user.UserID;
			this.fullName = user.FullName;
			this.email = user.Email;
			this.password = user.Password;
		}

		// Properties
		public string AuthenticationType
		{
			get { return "Custom Authentication"; }
		}

		public bool IsAuthenticated
		{
			get 
			{
				// assumption: all instances of a SiteIdentity have already
				// been authenticated.
				return true;

		}
