Windows 7 含以上支援 taskkill 指令，Windows XP 只支援 tskill 指令，所以這邊偷懶利用 try cache，當 taskkill 無法使用時換成 tskill。

利用指令關閉 iexplore.exe：

while (Process.GetProcessesByName("iexplore").Length > 0)
{
     Console.WriteLine("關閉瀏覽器");
     try {
          Process P = new Process();
          P.StartInfo.FileName = "taskkill";
          P.StartInfo.Arguments = "/F /IM iexplore.exe";
          P.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
          P.StartInfo.CreateNoWindow = true;
          P.Start();
          P.WaitForExit();
     }
     catch {
          Process P = new Process();
          P.StartInfo.FileName = "tskill";
          P.StartInfo.Arguments = "iexplore.exe /A /V";
          P.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
          P.StartInfo.CreateNoWindow = true;
          P.Start();
          P.WaitForExit();
     }
}

FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location).FileVersion.ToString()

首先加入Function

        /// <summary>
        /// 反序列化
        /// </summary>
        /// <param name="data"></param>
        /// <returns></returns>
        static T DoDeserialize<T>(string s)
        {
            XmlDocument XD = new XmlDocument();
            try
            {
                XD.LoadXml(s);
                XmlNodeReader XNR = new XmlNodeReader(XD.DocumentElement);
                XmlSerializer XS = new XmlSerializer(typeof(T));
                object obj = XS.Deserialize(XNR);
                return (T)obj;
            }
            catch
            {
                return default(T);
            }
        }
        /// <summary>
        /// 序列化
        /// </summary>
        /// <param name="obj"></param>
        /// <returns></returns>
        static string DoSerialize(object o)
        {
            XmlSerializer XS = new XmlSerializer(o.GetType());
            StringBuilder SB = new StringBuilder();
            StringWriter SW = new StringWriter(SB);
            XS.Serialize(SW, o);
            return SB.ToString();
        }

可以利用 Win32 API 控制 Console 視窗 最大化 或 最小化。

[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool SetWindowPos(
IntPtr hWnd,
IntPtr hWndInsertAfter,
int x,
int y,
int cx,
int cy,
int uFlags);
private const int HWND_TOPMOST = -1;
private const int SWP_NOMOVE = 0x0002;
private const int SWP_NOSIZE = 0x0001;

要控制視窗時只要呼叫：

IntPtr hWnd = Process.GetCurrentProcess().MainWindowHandle;
SetWindowPos(hWnd, new IntPtr(HWND_TOPMOST), 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);

可以利用 Win32 API 控制 Console 視窗 最大化 或 最小化。

[DllImport("User32")]
private static extern int ShowWindow(int hwnd, int nCmdShow);
private enum CommandShow : int { SW_HIDE = 0, SW_SHOWNORMAL = 1, SW_NORMAL = 1, SW_SHOWMINIMIZED = 2, SW_SHOWMAXIMIZED = 3, SW_MAXIMIZE = 3, SW_SHOWNOACTIVATE = 4, SW_SHOW = 5, SW_MINIMIZE = 6, SW_SHOWMINNOACTIVE = 7, SW_SHOWNA = 8, SW_RESTORE = 9, SW_SHOWDEFAULT = 10, SW_FORCEMINIMIZE = 11, SW_MAX = 11 } ;

將 iexplore.exe 視窗最大化：

Process[] p = Process.GetProcessesByName("iexplore");
if (p.Length > 0)
{
    for (int i = 0; i < p.Length; i++)
    {
        int hwnd = p[i].MainWindowHandle.ToInt32();
        ShowWindow(hwnd, (int)CommandShow.SW_NORMAL);
    }
}
p = null;

可以利用 Win32 API 控制 Console 視窗 最大化 或 最小化。

[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool SetWindowPos(
IntPtr hWnd,
IntPtr hWndInsertAfter,
int x,
int y,
int cx,
int cy,
int uFlags);
private const int HWND_TOPMOST = -1;
private const int SWP_NOMOVE = 0x0002;
private const int SWP_NOSIZE = 0x0001;

要控制視窗時只要呼叫：

ShowWindow(ThisConsole, MAXIMIZE);

.Net 可以使用 SquishIt 進行 CSS 及 JS 組合並壓縮，首先必須先下載檔案。

官方網址：http://www.codethinked.com/squishit-the-friendly-aspnet-javascript-and-css-squisher

本站下載：jetheredge-SquishIt-d9184c7

以往寫網頁會加入一堆 CSS 及 JS 如下：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <link href="CSS/a.css" rel="stylesheet" type="text/css" />
    <link href="CSS/b.css" rel="stylesheet" type="text/css" />
    <link href="CSS/c.css" rel="stylesheet" type="text/css" />
    <link href="CSS/d.css" rel="stylesheet" type="text/css" />
    <link href="CSS/e.css" rel="stylesheet" type="text/css" />
    <script src="JS/a.js" type="text/javascript"></script>
    <script src="JS/b.js" type="text/javascript"></script>
    <script src="JS/c.js" type="text/javascript"></script>
    <script src="JS/d.js" type="text/javascript"></script>
    <script src="JS/e.js" type="text/javascript"></script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    </div>
    </form>
</body>
</html>

當網頁讀取時需要載入多個 CSS 及 JS，這樣需要浪費較多的 Request 及頻寬，如下圖：

11次Request，約 295KB

如果檔案為 .Net 倒是很好處理，不過如果為 html 就沒辦法透過程式加上 Content-Type，所以此時只要修改 web.config 即可達到效果。

打開 web.config 進行編輯，在 <system.webServer> 下的 <staticContent> 裡加入以下：

      <remove fileExtension=".htm" />
      <mimeMap fileExtension=".htm" mimeType="text/html; charset=UTF-8" />
      <remove fileExtension=".html" />
      <mimeMap fileExtension=".html" mimeType="text/html; charset=UTF-8" />
