小技巧記錄一下：
 

string pattern = @"(?<MonthName>(JANUARY|FEBRUARY|MARCH|APRIL|MAY|JUNE|JULY|AUGUST|SEPTEMBER|OCTOBER|NOVEMBER|DECEMBER))\s*(?<Day>\d+)\s*,\s*(?<Year>\d{4})";

MatchCollection matchsetGameDate = Regex.Matches(pageSource, pattern, RegexOptions.Singleline | RegexOptions.IgnoreCase);
if(matchsetGameDate.Count == 0)
{	
	Common.WriteLog("匹配賽事清單網頁的賽事日期失敗！");
}
else
{
	try
	{
		foreach (Match matchGameDate in matchsetGameDate)
		{
			string dateString = matchGameDate.Groups["MonthName"].Value.ToUpper() + " " +
				matchGameDate.Groups["Day"].Value + " " +
				matchGameDate.Groups["Year"].Value;
			DateTime gameDate = DateTime.ParseExact(dateString, "MMMM d yyyy", CultureInfo.InvariantCulture);
			//do anything you want

		}
	}
	catch
	{
		
		Common.WriteLog("DateTime.ParseExact發生錯誤);
	}
}
