Question

我尝试附加某些自定义文档事件但有时会触发;有时他们不会。

更糟糕的是，这是一个可以测试的场景。我不确定这是否是我的操作系统问题。它是一台win7机器，安装了IE 11。

我启动了一个localhost python Web服务器并提供静态网页：

C:\code\forex> python -m SimpleHTTPServer 4542

并尝试在webbrowser控件中加载上述网页。所以我的表单代码有点如下：

using System;
using System.Diagnostics;
using System.Windows.Forms;

namespace winformWebBrowser
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

            webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted;            
            webBrowser1.Navigate("http://localhost:4542");

        }

        void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            if (webBrowser1.ReadyState == WebBrowserReadyState.Complete)
            {
                Debug.Print("Ready");
            }
        }
    }
}

我收到Ready消息。但是一旦我关闭表单，本地Web服务器也会因此而中断。

所以我的问题是webbrowser控件是否正常工作？

c＃webbrowser可靠吗？
