The sort order for files and folders whose names contain numerals is incorrect in sharepoint

Question

The sort order for files and folders whose names contain numerals is incorrect, such as my actually sort result is as following:

Ie4_01 Ie4_128 Ie401sp2 Ie5 Ie501sp2 Ie6

But my expected result is:

Ie4_01 Ie4_128 Ie5 Ie6 Ie401sp2 Ie501sp2

The issue is just as here http://social.technet.microsoft.com/Forums/en-US/sharepoint2010setup/thread/76b6f4d9-db1e-40a9-8407-13b8bcf6c1c3/ stated.

How can I resolve this issue? Thank you.

Answer 1

During a sort, the values are compared character by character.

This is normal behavior. 4 < 5 < 6, so that's how they should be sorted.

A < B < C, but you don't expect AZ to come after BA, because A < B

Answer 2

What you want is a alphanumeric sorting using an IComparer interface
