推荐答案

来自 MSDN:

GUID 是一个 128 位的值，由一组 8 个十六进制数字，其次是三组 4每个十六进制数字，后跟一组 12 个十六进制数字.以下示例 GUID 显示了十六进制数字的分组用户名: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

来自维基百科:

通常添加大括号来包围以上格式，例如:

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

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

所以在带花括号的典型十六进制编码中总共有 38 个字符.

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