推荐答案如果您不确定表达式,则应该花时间研究文档 [ ^ ].牢记这些概念很重要. If you are not sure about expressions then you should spend time studying the documentation[^]. It is important to get these concepts fixed in your mind.
第一种情况 First case int i = 10; int j = i++;
执行后, i的值为11 ,而 j的值为10 . 由于此运算符为POSTincrement,因此分配之后会自动发出通知. 第二种情况
After execution value of i would be 11 and value of j would be 10. As this operator is POSTincrement , increament will be done AFTER the assignement. Second case
int i = 10; int j = ++i;在执行的值后,我将为11 ,而 j的值将为11 . 由于此运算符是PREincrement,因此分配在之前会进行提示.
After execution value of i would be 11 and value of j would be 11. As this operator is PREincrement , increament will be done BEFORE the assignement.
hi 一次看这个 hi once lookat this string[] items = {"a","b","c","d"}; int i = 0; foreach (string item in items) { Console.WriteLine(++i); } Console.WriteLine(""); i = 0; foreach (string item in items) { Console.WriteLine(i++); }
输出将是
output will be
