设立一个定时器tmrMonitor，该定时器会在程序运行时不断把程序的占用内存和占用线程数写到LOG/MEM目录下。
我设置的定时器间隔是3000毫秒，记录后的信息可以用来分析一段时间内程序的运行状况，比如内存泄漏问题。

/// <summary>
/// Timer组件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 + "//Log";
    if (!Directory.Exists(LogAddress + "//MEM")) //需要System.IO
    {
        Directory.CreateDirectory(LogAddress + "//MEM");
    }

    LogAddress = String.Concat(LogAddress, "//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("进程标识： " + currentProcess.Id.ToString());
    sw.WriteLine("进程名称： " + currentProcess.ProcessName.ToString());
    sw.WriteLine("占用内存： " +
        (currentProcess.WorkingSet64 / 1024).ToString() + "KB");
    sw.WriteLine("线程数量： " + currentProcess.Threads.Count.ToString());
    sw.WriteLine();
    sw.Close();
}
