c# - asp.net c# 如何统计网站访问量

Question

如何在asp.net c#中统计网站访问量？

我正在使用下面的代码:

在 global.asax 页面中:

<%@ Application Language="C#" %>

void Application_Start(object sender, EventArgs e)
{
    // Code that runs on application startup
    Application["NoOfVisitors"] = 0;
}

void Session_Start(object sender, EventArgs e)
{
    // Code that runs when a new session is started
    Application.Lock();
    Application["NoOfVisitors"] = (int)Application["NoOfVisitors"] + 1;
    Application.UnLock();
}

在 .aspx 页面中:

<asp:Label runat="server" ID="lbluser" />

在 .aspx.cs 中:

protected void Page_Load(object sender, EventArgs e)
{
    lbluser.Text = Application["NoOfVisitors"].ToString();
}

应用程序计数器每隔一小时重置为 0 ...我在计算用户数量时哪里出错了？

应用程序状态是易变的。检查this MSDN articule :

When using application state, you must be aware of the following important considerations:

• ...

• Volatility Because application state is stored in server memory, it is lost whenever the application is stopped or restarted. For example, if the Web.config file is changed, the application is restarted and all application state is lost unless application state values have been written to a non-volatile storage medium such as a database.

所以你不应该用它来保存这种你想长期保存的数据。因为应用程序池会不时重置。我怀疑您不想在发生这种情况时重置您的访问者数量。

您需要某种数据存储，可以在您的应用程序未运行时保留您的数据。

这里有一些选择:

• 文件(XML、JSON、纯文本等):sample xml code for visitors counter
• 数据库(SQL Server、SQLite 等):sample database code for hit counter
