主要思路： 注:warehouse 为字符串数组，newstxt为要处理字符串
用C#中字符串的split()方法，以“.”为标志，将字符串切分成n段字符串放到warehouse字符串数组中。split()方法会错误的将形如U.S或者2.5hours的分到两个数组中这样的两个数组有一个规律，前者数组的末尾字符是数字或者大写字母，后者的开头字符对应的是数字或者大写字母。如果遇到着这种情况，就将两个数组合并成一个字符串，存放到前者字符串中，后者字符串由后面的字符串覆盖，以此类推，一直遍历到最后一个数组把倒数第二个数组的字符串给覆盖，数组长度减一。 string[] warehouse = newstxt.Split('.'); Boolean markItNumber = false; Boolean markItLetter = false; StringBuilder sb = new StringBuilder(); int count1 = 0; int mark = -1; int para_len = warehouse.Length; Console.WriteLine("\n\n\n******************调试台******************"); //对特殊情况进行处理 例如U.S 1.5hours char c = '0'; for (int o = 0; o < para_len; o++) { Console.WriteLine("开头字母"+ warehouse[o][0]+"结尾字母"+ warehouse[o][warehouse[o].Length-1]+ "markItLetter" + markItLetter+ "markItNumber"+ markItNumber); if (warehouse[o].Length > 0) { //如果开头是大写字母，那么检查上一句是否是大写字母结尾，如果是，那么把两句合并成一句 if (warehouse[o][0] >= 'A' && warehouse[o][0] <= 'Z') { if (markItLetter)//上一句是大写字母结尾 { Console.WriteLine("Last End:" + c + " Now Begin：" + warehouse[o][0]); warehouse[mark] = warehouse[mark] + "." + warehouse[o]; //将两个字符串合并，数组长度减1 for (int k = mark + 1; k < para_len - 1; k++) { warehouse[k] = warehouse[k + 1]; } para_len--; --o; // 重新从最新合并的字符串开始处理 } markItLetter = false; } else if (warehouse[o][0] >= '0' && warehouse[o][0] <= '9') { if (markItNumber) //上一句是数字结尾 { Console.WriteLine("Last End:" + c + " Now Begin:" + warehouse[o][0]); warehouse[mark] = warehouse[mark] + "." + warehouse[o]; //将两个字符串合并，数组长度减1 for (int k = mark + 1; k < para_len - 1; k++) { warehouse[k] = warehouse[k + 1]; } para_len--; --o; } markItNumber = false; } if(warehouse[o][warehouse[o].Length-1]>='A' && warehouse[o][warehouse[o].Length - 1] <= 'Z') { markItLetter = true; mark = o; c = warehouse[o][warehouse[o].Length - 1]; Console.WriteLine("Last End:" + c ); } else if(warehouse[o][warehouse[o].Length - 1]>='0' && warehouse[o][warehouse[o].Length - 1] <= '9') { markItNumber = true; mark = o; c = warehouse[o][warehouse[o].Length - 1]; Console.WriteLine("Last End:" + c); } } } len = para_len; Console.WriteLine("\n\n\n******************调试结束******************");
