Creating different GUID for same lowercase and upper case strings

问题

When I try to create GUIDs like this

Guid guid1 = Guid.Parse("aaaaaaaa-bbbb-cccc-eeee-ffffffffffff");
Guid guid2 = Guid.Parse("AAAAAAAA-BBBB-CCCC-EEEE-FFFFFFFFFFFF");

Both are creating same GUID object. Is it possible to create unique GUIDs for lower case and upper case version of same string?

Any ideas are welcome.

回答1:

GUIDs are actually bytes parsed from hexadecimal.
That is not possible.

You should not use GUIDs to store arbitrary data.

回答2:

Your strings are hexadecimal representations of the same value because hexadecimal is not case sensitive.

Your request is like saying that you don't want 0.5 to equal 1 / 2. They are different representations of the same value.

Perhaps you need a different method of generating GUIDs.
