ASP 锁定和解锁 方法


❮ Application 对象完整参考

Lock 方法

Lock 方法阻止其他用户修改 Application 对象中的变量(用于确保一次只有一个客户端可以修改 Application 变量)。

Unlock 方法

Unlock 方法允许其他用户修改存储在 Application 对象中的变量(在使用 Lock 方法锁定后)。

语法

Application.Lock

Application.Unlock

示例

下面的示例使用 Lock 方法来防止多个用户同时访问变量 visits,并使用 Unlock 方法解锁锁定的对象,以便下一个客户端可以递增变量 visits。

<%
Application.Lock
Application("visits")=Application("visits")+1
Application.Unlock
%>

此页面已被访问
<%=Application("visits")%> 次!
