FIX: The Regex class and the Match class may not correctly find matches for a regular expression (822923)
The information in this article applies to:
- Microsoft .NET Framework 1.0
SYMPTOMSWhen you use certain Regex patterns to search a regular
expression, you can obtain incorrect results.
For
example, you expect the following two expressions to return the
same results: "([^{}]|\n)*" ""([^{}])*"
However,
the first expression, "([^{}]|\n)*", does not return the correct results. The
hotfix that this article describes resolves the problem. CAUSEThis problem occurs because of the way that the RegEx optimizer handles
certain strings.RESOLUTIONA supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article.
