Monotouch iOS中SOAP响应中的System.DateTime.ParseExact错误


System.DateTime.ParseExact error in SOAP response in Monotouch iOS

我有一个正在对另一个应用程序进行SOAP Web服务调用的应用程序(这里没有JSON的可能性)。一些回应还不错。问题是，其中一个调用已确定，但响应返回了System.DateTime.ParseExact错误。我在SOAPUI中检查了日期格式，它返回为：2012-02-05-05:00

错误消息是：

几年前，我已经看到了这一点，这使我无法将多个Web服务项目移植到Mono。我可以确定Mono的行为不同于Microsoft .Net。我尚不清楚这是否是一个错误，但是许多Web服务以" yyyy-mm-dd"以外的格式返回日期，有些添加了" Z"或其他时区规范，有些则有时间。您可以修补Mono以使用System.DateTime.Parse，但是为此不得不使用自定义Mono构建很麻烦。

这看起来不像是一个问题(请参阅注释)，但是，如果我弄错了，这里是为什么...

1
case"date": return DateTime.ParseExact (value,"yyyy-MM-dd", null);

这是XmlCustomFormatter.cs(在github上提供的源代码)中的第275行，该行显示了Mono预期日期的格式(对还是错)。

这与您在问题中提供的2012-02-05-05:00字符串不匹配，这会导致您现在遇到异常。这可能是Mono中的错误，或者，如果Microsoft实现的行为相同，则可能是您正在调用的Web服务出现问题。

注意：错误报告将在http://bugzilla.xamarin.com
