                     break;//找到并替换后跳出循环，省点时间
                }
                else
                {
                     r1 = r1.NextStoryRange;
                }        //加上这个if语句可以提高一点效率，但还是比较慢      
                         }        while        (r1 !=        null       );       
                      }       
                  }       
                  #endregion       
       }      
       有哪位高手能解释下这段代码，我目前只会用，不理解，谢谢
