http://bugzilla.novell.com/show_bug.cgi?id=572874#c0 Summary: ValueType.Equals fails on structs containing nullables Classification: Mono Product: Mono: Class Libraries Version: 2.6.x Platform: All OS/Version: Windows Vista Status: NEW Severity: Major Priority: P5 - None Component: CORLIB AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: --- Blocker: --- Created an attachment (id=338176) --> (http://bugzilla.novell.com/attachment.cgi?id=338176) Patch to apply to the trunk, which adds a test for this bug. User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 GTB6 (.NET CLR 3.5.30729) When comparing struct data that are exact copies of each other, the result would incorrectly indicate that they are different if any nullable data-type is part of of the data structure's definition. Reproducible: Always Steps to Reproduce: 1. Define a struct data-type that contain a nullable type, e.g., Nullable<int> 2. Create two instances of the defined struct, for example named x and y, and populate both with the exact same data 3. Compare the two instances using x.Equals(y), which would use ValueType.Equals for the comparison Actual Results: False is returned from ValueType.Equals Expected Results: ValueType.Equals must return true in this case This bug is not specific to Windows, but was detected on openSUSE 11.1 as well. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
