编程之美 让CPU占用率曲线听你指挥

例子：

public void PublishDetailItem(object obj)
        {
            Usp_Gif_GetGifInfosResult gif = obj as Usp_Gif_GetGifInfosResult;
            string content = string.Empty;
            string imgDetailPath = string.Empty;
            imgDetailPath = string.Format(MyConfig.GifLibResDirPath_Publish + "{0}\\{1}-{2}.html", gif.TagSpell, gif.TagID.ToString(),
                        gif.GifID.ToString());
            content = RequestHelper.DownLoadHtml(string.Format(MyConfig.GetQQtuHref
                + "detail.aspx?tagid={0}&gifid={1}", gif.TagID.ToString(), gif.GifID.ToString()), null, Encoding.UTF8);
            FileHandler.WriteOnce(imgDetailPath, content, Encoding.UTF8);
            threadFlag++;

            PerformanceCounter p = new PerformanceCounter("Processor", "% Processor Time", "_Total");
            while (true)
            {
                if (p.NextValue() > 50.0)
                {
                    Thread.Sleep(1000);
                }
            }
        }
