1.3、Guid
包含下面任一格式的 GUID 的字符串（“d”表示忽略大小写的十六进制数字）：
所有内置的空格都将被忽略。 组中的所有前导零都将被忽略。 组中显示的数字为可在该组显示的有意义数字的最大数目。 您可以指定从 1 到为组显示的位数。
指定的位数被认为是该组低序位的位数。
| 格式描述 | 支持的Format | 备注 |
| 32 个连续的数字 | dddddddddddddddddddddddddddddddd | |
| 8、4、4、4 和 12 位数字的分组，各组之间有连线符。 | dddddddd-dddd-dddd-dddd-dddddddddddd {dddddddd-dddd-dddd-dddd-dddddddddddd} (dddddddd-dddd-dddd-dddd-dddddddddddd) |
也可以用一对大括号或者圆括号将整个 GUID 括起来 |
| 8、4 和 4 位数字的分组，和一个 8 组 2 位数字的子集，每组都带有前缀“0x”或“0X”，以逗号分隔。 | {0xdddddddd, 0xdddd, 0xdddd,{0xdd,0xdd,0xdd,0xdd,0xdd,0xdd,0xdd,0xdd}} | 整个 GUID 和子集用大括号括起来。 所有大括号、逗号和“0x”前缀都是必需的。 |
