{ if (Session[ " name " ] == null ) Response.Write( " <script>alert('请登陆');location.href='login.aspx';</script> " ); else if ((Cache[ " userlist " ] as System.Collections.Generic.Dictionary < string , string > )[Session[ " name " ].ToString()] != Session.SessionID) Response.Write( " <script>alert('已经有相同帐号登陆');location.href='login.aspx';</script> " );} (编辑:安卓应用网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
