问题描述

我如何创建一个计数器来统计访问者的数量?

How can I make a counter which counts the number of visitors?

推荐答案

您可以使用应用程序级变量并利用Global.asax中的事件

步骤:

1.声明变量

Hi,

u can use Application level variables and make use of the events in Global.asax

Steps:

1. Declare Variables

private static int totalNumberOfUsers = 0;
    private static int currentNumberOfUsers = 0;

2.添加属性

2. Add Properties

public static int TotalNumberOfUsers
{
  get
  {
    return totalNumberOfUsers;
  }
}

public static int CurrentNumberOfUsers
{
  get
  {
    return currentNumberOfUsers;
  }
}

3.会话开始事件

3. Session Start Event

protected void Session_Start(Object sender, EventArgs e)
{

  totalNumberOfUsers += 1;
  currentNumberOfUsers += 1;

}

4.会话结束事件

4.Session End Event

protected void Session_End(Object sender, EventArgs e)
{
  currentNumberOfUsers -= 1;

}

5.从其他页面访问变量

5.Access variables from other page

int currentNumberOfUsers = HitCounters.Global.CurrentNumberOfUsers;
int totalNumberOfUsers = HitCounters.Global.TotalNumberOfUsers;

:thumbsup: Revert for further clarification

对于Web应用程序，请尝试:
在与整个应用程序交互的 Global.asax 文件中编写代码.
示例代码如下:

For web application, try:
Write code in Global.asax file which interacts with the entire application.
The sample code is given below:

void Application_OnStart(Object Sender, EventArgs E)
        {
            Application["CurrentUsers"] = 0;
        }
        void Session_OnStart(object Sender, EventArgs E)
        {
            Application.Lock();
            Application["CurrentUsers"] = System.Convert.ToInt32(Application["CurrentUsers"]) + 1;
            Application.UnLock();
        }
        void Session_OnEnd(object Sender, EventArgs E)
        {
            Application.Lock();
            Application["CurrentUsers"] = System.Convert.ToInt32(Application["CurrentUsers"]) - 1;
            Application.UnLock();
        }
