和
Regex reg = new Regex("-");
string[] str = reg.Split("one-two-three");
的区别。
加括号和不加括号有什么区别
输出分别为：one         one
                        -            two
                     two          three
                       -
                    three

作业1中
checknumber要求单个"-","+","."返回错误
最后为"."时返回错误。
if ((str[str.Length - 1] == '.') || (str[str.Length - 1] == '-') || (str[str.Length - 1] == '+'))
  {
          return false;
   }
我觉得这段代码可以实现以上4个功
