Assignments for the first Software Engineering Course

It is estimated that one day is required before the job is completed. It actually takes one and a half days, and the main time is spent searching for related classes, function calls, and debugging bugs.

This job is very difficult to complete. The first failure was to use a limited String Array Storage, which led to the later running of large data volumes of Files
Overflow, followed by the C # file written in the C style, which increases the difficulty of debugging, and finally lacksAlgorithmOptimization, reading data and sorting function flower
.
The biggest achievement was the initial study of C #, the first contact with C #. On C #, I am very happy to see that Java is familiar with classes, encapsulation, and so on.
After finishing this assignment, I checked the classes provided by msdn and C #. The methods are impressive. In turn, I will be reminded to use arraylist more next time, and I will write my own mails in C #.
Installation Method to improve efficiency.

The figure shows that the main time is spent on streamwriter ?!
