推荐答案

创建一个全局datetime变量，并在用户成功登录时以及用户注销得到当前datetime与您设置的变量之间的差时进行设置一开始

make a global datetime variable and set it when the user is login successfully and when the user logout get the difference between the current datetime and the variable you set it in the beginning

DateTime loginDate = new DateTime();
double  sessionHours = (DateTime.Now - loginDate).TotalHours;

您可以检查其他可以检索的数据，例如天，分钟，秒等.

希望我能帮上忙

You can check the other data you can retrieve like days , minutes , seconds and etc

Hope i could help
