推荐答案

从 MSDN ：

GUID是一个128位值，由
一组8个十六进制数字，
后面是三组4
十六进制数字，后跟
一组12个十六进制数字。
以下示例GUID显示
GUID中的
分组十六进制数字：
6B29FC40-CA47-1067-B31D-00DD010662DA

A GUID is a 128-bit value consisting of one group of 8 hexadecimal digits, followed by three groups of 4 hexadecimal digits each, followed by one group of 12 hexadecimal digits. The following example GUID shows the groupings of hexadecimal digits in a GUID: 6B29FC40-CA47-1067-B31D-00DD010662DA

从维基百科：

通常会添加大括号以包含以上格式的
：

Often braces are added to enclose the above format, as such:

{3F2504E0-4F89-11D3-9A0C-0305E82C3301}

所以共有38个字符的典型十六进制编码与花括号。

So a total of 38 characters in the typical hexadecimal encoding with curly braces.
