我想printf("%+'10d")
一个整数。
找不到string.Format
的等效语法。
你能救我吗?
printf("%+'10d %+'10d %+'10d", 0, -102048224, 4865284)
会显示:
+0 -102,048,224 +4,865,284
然而:
string.Format("{0,10:+#;-#;0} {1,10:+#;-#;0} {2,10:+#;-#;0}", 0, -102048224, 4865284)
给出(没有逗号,我不关心+ 0对0):
0 -102048224 +4865284
和
string.Format("{0,10:n0} {1,10:n0} {2,10:n0}", 0, -102048224, 4865284)
给出(最后一个数字没有正号):
0 -102,048,224 4,865,284

答案 0 :(得分:4)
这应该可以解决问题:
example
mysql> SELECT * FROM MAXWELL;
+------+-------+
| ID | NAME |
+------+-------+
| 3 | TWO |
| 4 | FOUR |
| 5 | FIVE |
| 6 | SIX |
| 7 | SEVEN |
+------+-------+
5 rows in set (0.00 sec)
mysql> SELECT * FROM MAXWELL limit 0,2;
+------+------+
| ID | NAME |
+------+------+
| 3 | TWO |
| 4 | FOUR |
+------+------+
2 rows in set (0.00 sec)
mysql> SELECT * FROM MAXWELL limit 2,4;
+------+-------+
| ID | NAME |
+------+-------+
| 5 | FIVE |
| 6 | SIX |
| 7 | SEVEN |
| 10 | ten |
+------+-------+
4 rows in set (0.00 sec)
打印:
string.Format("{0:+#,0.##;-#,0.##} {1:+#,0.##;-#,0.##} {2:+#,0.##;-#,0.##}", 0, -102048224, 4865284)
将数字对齐到右边:(13是任意的,选择适合你的数字)
+0 -102,048,224 +4,865,284
打印:
string.Format("{0,13:+#,0.##;-#,0.##}\n{1,13:+#,0.##;-#,0.##}\n{2,13:+#,0.##;-#,0.##}", 0, -102048224, 4865284);
