Parameters

g
Type: System.String
A String that contains a GUID in one of the following formats ('d' represents a hexadecimal digit whose case is ignored):
32 contiguous digits:
dddddddddddddddddddddddddddddddd
-or-
Groups of 8, 4, 4, 4, and 12 digits with hyphens between the groups. The entire GUID can optionally be enclosed in matching braces or parentheses:
dddddddd-dddd-dddd-dddd-dddddddddddd
-or-
{dddddddd-dddd-dddd-dddd-dddddddddddd}
-or-
(dddddddd-dddd-dddd-dddd-dddddddddddd)
-or-
Groups of 8, 4, and 4 digits, and a subset of eight groups of 2 digits, with each group prefixed by "0x" or "0X", and separated by commas. The entire GUID, as well as the subset, is enclosed in matching braces:
{0xdddddddd, 0xdddd, 0xdddd,{0xdd,0xdd,0xdd,0xdd,0xdd,0xdd,0xdd,0xdd}}
All braces, commas, and "0x" prefixes are required. All embedded spaces are ignored. All leading zeroes in a group are ignored.
The digits shown in a group are the maximum number of meaningful digits that can appear in that group. You can specify from 1 to the number of digits shown for a group. The specified digits are assumed to be the low order digits of the group.
