推荐答案

CREATE TABLE USERLOG(
   ID INT IDENTITY(1,1) PRIMARY KEY NOT NULL,
   USERID INT,
   LOGIN DATETIME,
   LOGOUT DATETIME
)

CREATE PROCEDURE SP_TRACK_USERLOG
	@USERID INT = NULL,
	@COMMAND INT = 0
AS
BEGIN
	SET NOCOUNT ON;
	IF(@COMMAND = 0)
		BEGIN
			INSERT INTO USERLOG (USERID,LOGIN,LOGOUT) VALUES (@USERID,GETDATE(),NULL)
		END
	ELSE IF (@COMMAND = 1)
		BEGIN
			UPDATE USERLOG SET LOGOUT = GETDATE() WHERE USERID = @USERID
		END
END

SqlConnection cs = new SqlConnection("YOUR CONNECTION STRING");
cs.Open();
SqlCommand cmd = new SqlCommand();
public void Login(int userID)
{            
   cmd.Connection = cs;
   cmd.CommandType = CommandType.StoredProcedure;
   cmd.CommandText = "SP_TRACK_USERLOG";
   cmd.Parameters.AddWithValue("@USERID", userID);
   cmd.Parameters.AddWithValue("@COMMAND", 0);
   cmd.ExecuteNonQuery();
}
public void LogOut(int userID)
{
   cmd.Connection = cs;
   cmd.CommandType = CommandType.StoredProcedure;
   cmd.CommandText = "SP_TRACK_USERLOG";
   cmd.Parameters.AddWithValue("@USERID", userID);
   cmd.Parameters.AddWithValue("@COMMAND", 1);
   cmd.ExecuteNonQuery();
}

在成功登录和注销事件后获取System.DateTime.Now的值，并将其存储到数据库中.
您还需要做其他事情吗?

Take the value of System.DateTime.Now after successful login & logout events and store it into database.
Do you need anything else to be done?

使用session_start和session_end事件.

在Session_start事件中，编写用于登录数据库表的代码
在session_end事件中，编写用于登出DB表的代码

尝试一些代码如果有任何错误，请使用代码发布您的问题

最好的

Hi,

use session_start and session_end events.

In Session_start event write code for login in DB table
In session_end event write code for logout in DB Table

Try yourself some code If there are any error post your question with code

All the Best
