Compilation Principle Course .... Temporarily easy

I did not expect yesterday to be overnight. Today I still wrote three points .... I have been nervous about it. After I think about it, I feel as tired as a dog ..... I wrote my own course in C # and wrote a simple page.

In fact, I feel that something can be done quickly, but it takes a long time for me to get down to some low-level errors because I am not proficient in some things and careless things...

The most embarrassing problem is the escape of regular expressions. I used several replace pairs to replace the +-* and other symbols with escape characters. Because the formula is very long, I wrote it down in one stop .. however, the test fails.

The problem is so funny that it turns out that "/" has become "//". I am very puzzled... is it true that I have reversed the meaning? I searched the internet for a long time, and finally found the problem on myself, in the last sentence of replace.

I wrote Replace ("\", @ "\"); ...... at that time, I was really helpless ~ Too careless... another problem is the UE's drag problem. I want to make a drag effect... unfortunately, winform's performance and encapsulation .....

After a long time of trouble, I finally gave up... it is really troublesome to ask for the question of the VT set. I think it saves a lot of trouble to use regular expressions. If I use C/C ++ to write it, it would be crazy... fortunately, this is not the question that xieni has drawn .....

It's so sleepy. I haven't slept for more than 36 hours. I think about the three-day busy schedule. I have a good night's sleep today.
