发帖数: 114 | 2 1.Write a small project
Open folder and Open every file.
You can think and set all the conditions about phone number.
In this case, i would like to set phone number format as follows.
FIRST OF ALL, DELTE SPACE, THUS , USE REPLACE method.
Then , replace all the '-', then replace all the '(', then replace all the '
)',
Okay, then use indexof , might be instr, to find 0123456789.
And if found, keep folder path and file name to save into file by using
streamwriter class.
2. the file looks like EMAIL;
Thus, you should can import into outlook. And using outlook's search
function, search title, content, from, to . then find all the files
including this phone number. | c****p

I think he just want to filter out the phone number from other text in the
file instead of seaching a specific phone number. The file format could be
any type, not limited to email or html ...

grep "(\d{10})|(\d{3}[ ]\d{3}[ ]\d{4})" /files | S**********n
发帖数: 250 | 7 我也支持状态机的解法。
就是画一个DFA（Deterministic Finite Automata）的图，然后状态机的代码就自然写
出来了。
几乎一模一样题，我以前学compiler的时候，是第一个星期的家庭作业：三种类型的电
话号码
1234567890
123-456-7890
（123）456-7890
不过当时跟你这个有个不同的是，我们没要求考虑“很多”的“大”的文件。不知道你
是不是还要考虑这方面。
