这两个方法，什么作用？？？

[jiaqi_006]

public void Dispose()
{
#if DEBUG
stopWatch.Stop();

double duration = ( double ) stopWatch.ElapsedMilliseconds / 1000.0;

m_cmd = String.Format( "{0}: {1:N3}", m_cmd, duration );
问题一：这里将字符串转化为了什么？是不是“m_cmd:duration:N3”？？？


if ( HttpContext.Current.Items ["TimeQueries"] == null )
HttpContext.Current.Items ["TimeQueries"] = duration;
else
HttpContext.Current.Items ["TimeQueries"] = duration + ( double ) HttpContext.Current.Items ["TimeQueries"];

if ( HttpContext.Current.Items ["CmdQueries"] == null )
HttpContext.Current.Items ["CmdQueries"] = m_cmd;
else
HttpContext.Current.Items ["CmdQueries"] += "<br/>" + m_cmd;
#endif
}

问题二：这是做了什么样的处理？为什么要做这样的处理？？？


#if DEBUG
static public void Reset()
{
HttpContext.Current.Items ["NumQueries"] = 0;
HttpContext.Current.Items ["TimeQueries"] = ( double ) 0;
HttpContext.Current.Items ["CmdQueries"] = "";

问题三：这三个参数分别表示什么？在Http请求中有什么样的作用？

好象是看执行了多少时间呢.吧

参数自己定义的吧。。。就是标示 name
