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。

复制代码 代码如下:
/// <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();
}
