推荐答案

您可以通过保存到数据文件或更新数据库中的用户表来跟踪谁登录有一列用作标志。然后使用诸如从登录名为1的用户中选择名称之类的查询。

You could track who's logged in by saving into a data file or updating a User table in a database which has a column used as a flag. Then use a query such as 'select Names from Users where Login=1'.

可能有更好的方法，但如果没有别的，你应该能够在global.asax中保存它，一个单身人士班。只需使用用户名创建一个字符串列表，然后将用户附加到列表中，并使用列表计数作为您的总用户数。但我怀疑有这样的标准方法来做这样的事情。但如果你找不到一个好的解决方案，你可以很容易地自己构建它。

There may be better ways, but if nothing else you should be able to hold this in a global.asax, a singleton class. Just create a string list with the user name, then append the users to your list and use the lists count for your total number of users. But I suspect there are standard approaches to doing such as thing as this. But if you cannot find a good solution, you could build it out yourself pretty easily.
