Description Horst Kakuschke 2013-12-11 14:04:57 UTC
XmlConvert.ToDateTime(string, XmlDateTimeSerializationMode) throws an "index out of bounds" exception in 
DateTime._DoParse() when the xml dateTime string is e.g.
- "2003-09-26T13:30:44Z"
- "2003-09-26T13:30:44+13:00".

On the other hand, converting of "2003-09-26T13:30:44" works fine.

To reproduce the exception:

  DateTime x = XmlConvert.ToDateTime("2003-09-26T13:30:44Z", XmlDateTimeSerializationMode.Local);
Comment 1 Horst Kakuschke 2013-12-11 14:27:03 UTC
Primary culprit was a index check in Corlib/System/DateTime.cs - fixed.

Added tests for method XmlConvert.ToDateTime(string, XmlDateTimeSerializationMode) in System.XML/Test/System.XML/XmlConvertTests.cs and found quite a few differences between MS .NET and Mono (ran the tests first in .NET, then on Mono).

Fixed these differences in System.XML/System.Xml/XmlConvert.cs: now .NET and Mono yield the same results.

Created GitHub pull request #835 - please check.
