private static void TShowArray(object[] array){ foreach (object o in array) { Console.WriteLine(o.ToString()); }}public void TRegex(){string[] split4 = Regex.Split("fcatcat123ds catdog129 catcatdogdog23 catcatdog99", @"(cat)+(dog)?/d", RegexOptions.IgnoreCase);TShowArray(split4);Console.WriteLine("----------------------------");string[] split3 = Regex.Split("AAA<sample>BBB<Sample2>CCC", "(<sample>)+|(<sample2>)+", RegexOptions.IgnoreCase);TShowArray(split3);Console.WriteLine("----------------------------");string[] split2 = Regex.Split("AAA<sample>BBB<Sample>CCC", "(<sample>)+", RegexOptions.IgnoreCase);TShowArray(split2);Console.WriteLine("----------------------------");string[] split1 = Regex.Split("AAA<sample>BBB<Sample>CCC", "<sample>", RegexOptions.IgnoreCase);TShowArray(split1);}

运行完后结果是：

f
cat
23ds
cat
dog
29 catcatdogdog23
cat
dog
9

----------------------------

AAA
<sample>
BBB
<Sample2>
CCC
----------------------------
AAA
<sample>
BBB
<Sample>
CCC
----------------------------
AAA
BBB
CCC

有分组的时候，也被分了。。。并且也保存了记录
