//WebConfig配置
出于安全性的考虑，ASP.NET AJAX的Profile Service在默认情况下不会开放Profile的访问权限

  <system.web.extensions>
    <scripting>
      <webServices>
        <profileService enabled="true"
                        readAccessProperties="Name, Age, Email, Address.City, Address.Street, Address.PostalCode"
                        writeAccessProperties="Name, Age, Email, Address.City, Address.Street, Address.PostalCode" />
      </webServices>
    </scripting>
  </system.web.extensions>
