These days are watching C # Primer Plus, but the front two chapters are all theory. It feels very boring, it is difficult to understand. Today, I have read the second chapter today, I have officially started learning and writing programs, huh, interest It's up, I wrote the first CS file! Oh, I think I will learn more. I haven't encountered any difficult problems today, but the concept of "pseudo code" in C # is not too clear. . .
