http://bugzilla.novell.com/show_bug.cgi?id=572540#c0 Summary: Linq query ignores more than two orderby keys Classification: Mono Product: Mono: Compilers Version: 2.6.x Platform: All OS/Version: Ubuntu Status: NEW Severity: Normal Priority: P5 - None Component: C# AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: --- Blocker: --- Created an attachment (id=337859) --> (http://bugzilla.novell.com/attachment.cgi?id=337859) Example program source demonstrating the bug User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.3) If a linq query uses an orderby clause with more than two values, the compiler uses only the first two and ignores the rest. This can be seen when viewing the resulting IL; the compiler will output a call to Enumerable.OrderBy for the first sort key, and a call to Enumerable.ThenBy for the second sort key, but it does not emit a call to Enumerable.ThenBy for any of the remaining sort keys. This is strictly a compiler bug, because manually calling ThenBy the appropriate number of times does yield the correct result. Reproducible: Always Steps to Reproduce: 1. Write a program with a linq expression that sorts on more than two sort keys (an example is attached to this bug report). 2. Compile this program with gmcs. 3. Run it to observe incorrect behaviour. Actual Results: The gmcs compiler emits code to sort by the first two keys, but not by the remaining keys. Expected Results: The compiler should emit code to use all the specified sort keys. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
