ASP.NET：性能计数器不显示任何内容

我是 asp.net、C# 等方面的完全初学者...

然后我尝试这个：

using System;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.IO;
using System.Text;
using System.Net;
using System.Collections.Generic;
using System.Xml;

using System.Collections;
using System.Collections.Specialized;
using System.Diagnostics;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

        Response.Write("Hello from code behind");

        PerformanceCounter cpuload = new PerformanceCounter();
        cpuload.CategoryName = "Processor";
        cpuload.CounterName = "% Processor Time";
        cpuload.InstanceName = "_Total";

        //or PerformanceCounter cpuload = new PerformanceCounter("Processor", "% Processor Time", "_Total");

        Console.WriteLine(cpuload.NextValue() + "%");

    }
}

但这只显示 Hello from code Behind< /代码>。为什么请？

I am a complete beginner in asp.net, C#, etc...

I saw this and this

Then I try this:

using System;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.IO;
using System.Text;
using System.Net;
using System.Collections.Generic;
using System.Xml;

using System.Collections;
using System.Collections.Specialized;
using System.Diagnostics;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

        Response.Write("Hello from code behind");

        PerformanceCounter cpuload = new PerformanceCounter();
        cpuload.CategoryName = "Processor";
        cpuload.CounterName = "% Processor Time";
        cpuload.InstanceName = "_Total";

        //or PerformanceCounter cpuload = new PerformanceCounter("Processor", "% Processor Time", "_Total");

        Console.WriteLine(cpuload.NextValue() + "%");

    }
}

But that only displays Hello from code behind. Why please?

您正在写入控制台，这是行不通的，请改为写入响应（就像您的字符串一样）：

Response.Write(cpuload.NextValue().ToString() + "%");

虽然严格来说不是控制台应用程序的应用程序类型可以具有关联的控制台，但除非明确指定，否则它们是不可见的这样做了，并且不能在网络应用程序中。

You're writing to the console, which won't work, write to the response instead (just as your string does):

Response.Write(cpuload.NextValue().ToString() + "%");

While applications types that aren't strictly console applications can have an associated console, they're not visible unless explicitly made so, and couldn't be in a web application.
