設立一個定時器tmrMonitor，該定時器會在程序運行時不斷把程序的占用內存和占用線程數寫到LOG/MEM目錄下。
我設置的定時器間隔是3000毫秒，記錄后的信息可以用來分析一段時間內程序的運行狀況，比如內存泄漏問題。

/// <summary>
/// Timer組件tmrMonitor的Tick事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void tmrMonitor_Tick(object sender, EventArgs e)
{
    string LogAddress = Environment.CurrentDirectory + "http://Log";
    if (!Directory.Exists(LogAddress + "http://MEM")) //需要System.IO
    {
        Directory.CreateDirectory(LogAddress + "http://MEM");
    }

    LogAddress = String.Concat(LogAddress, "http://MEM//",
        DateTime.Now.Year, '-', DateTime.Now.Month, '-',
        DateTime.Now.Day, "_mem.log");

    //需要 System.Diagnostics;
    Process currentProcess = Process.GetCurrentProcess();

    StreamWriter sw = new StreamWriter(LogAddress, true);
    sw.WriteLine('[' + DateTime.Now.ToString() + ']');
    sw.WriteLine("進程標識： " + currentProcess.Id.ToString());
    sw.WriteLine("進程名稱： " + currentProcess.ProcessName.ToString());
    sw.WriteLine("占用內存： " +
        (currentProcess.WorkingSet64 / 1024).ToString() + "KB");
    sw.WriteLine("線程數量： " + currentProcess.Threads.Count.ToString());
    sw.WriteLine();
    sw.Close();
}
