基于.net的principal、identity接口的用户处理机制。
SiteIdentity.cs
using System;
using System.Text;
using System.Collections;
using System.Security.Cryptography;
namespace ContextUser

/// <summary>
/// SiteIdentity 的摘要说明。

private string userName;
private string emailAddress;

public SiteIdentity(string currentUserName )
{

}
public string AuthenticationType
{
get
{

}
set
{

}
public bool IsAuthenticated
{

{
// assumption: all instances of a SiteIdentity have already

public string EmailAddress
{

public int UserID

SitePrincipal.cs

下面继承page 用于需要验证的页面继承
