使用

Response.Redirect("login.aspx"); /
如果有任何内容，请清除上一个会话

谢谢，

如果您使用的是FormsAuthentication，请在注销"按钮上单击以编写以下代码

 Session.Clear();
Session.Abondon();
FormsAuthentication.SignOut();
Response.Redirect(" );

如果您不使用FormsAuthentication，则只需

 Session.Clear();
Session.Abondon();
Response.Redirect(" );

将起作用.

 FormsAuthentication.SignOut();
会话[" ].Abandon();
Response.Redirect(" ); 

并在

 login.aspx 

页面加载事件中编写以下语句.

 Response.Cache.SetNoStore(); 

它应该是页面加载事件中的第一声明.
如果您使用的是母版页，则在母版页加载事件中编写以上语句.

hi, If you are using FormsAuthentication then on Logout Button click write the following code

Session.Clear();
Session.Abondon();
FormsAuthentication.SignOut();
Response.Redirect("Home.aspx");

and if you are not using FormsAuthentication then simply

Session.Clear();
Session.Abondon();
Response.Redirect("Home.aspx");

will work.

Write the following logout code in logout button click event

FormsAuthentication.SignOut();
Session["Name"].Abandon();
Response.Redirect("Login.aspx");

and in

login.aspx

page load event write the following statement.

Response.Cache.SetNoStore();

it should be the first statement in the page load event.
if you are using the master pages then write the above statement in the master page load event.
