As part of my series on SharePoint auditing, I will demonstrate how to read from the audit log. This is useful if you are restricted to Windows SharePoint Service or SharePoint Foundation, where the out-of-the-box reports are not available, or just need to make your own custom reports.
The auditing is centered around the SPAudit class, which is available in all versions of SharePoint 2007 and SharePoint 2010, except in sandboxed solutions.
