正则表达式

提取名称=值对

 

string r = @"(?m)^\s*(?'name'\w+)\s*=\s*(?'value'.*)\s*(?=\r?$)";

string text =
  @"id = 3
    secure = true
    timeout = 30";

foreach (Match m in Regex.Matches (text, r))
  Console.WriteLine (m.Groups["name"] + " is " + m.Groups["value"]);

解析日期和时间

string r = @"(?x)(?i)
 (\d{1,4}) [./-]
 (\d{1,2}) [./-]
 (\d{1,4}) [\sT]  (\d+):(\d+):(\d+) \s? (A\.?M\.?|P\.?M\.?)?";

string text = "01/02/2008 5:20:50 PM";

foreach (Group g in Regex.Match (text, r).Groups)
  Console.WriteLine (g.Value + " ");
