Deserialize XML dateTime to UTC

问题

I am consuming an XML webservice with XSD elements such as:

<xs:element nillable="true" type="xs:dateTime" name="ENDDATE"/>

XML might look like the following:

<ENDDATE>2016-08-01T18:35:49+04:00</ENDDATE>

I used XSD.exe to autogenerate C# classes, when I inspect these the DateTime object will contain the time in system-local time, with Kind==Local.

Is there a way I can force the DateTime instances to be in UTC time without manually hacking the auto-generated classes for every such field (there are rather a lot)?

回答1:

I think that you can't tune this behavior using XSD (see here). So you should update(hack) auto-generated classes and do something like described there:

[XmlIgnore()]
public DateTime Time { get; set; }

[XmlElement(ElementName = "Time")]
public string XmlTime
{
    get { return XmlConvert.ToString(Time, XmlDateTimeSerializationMode.RoundtripKind); }
    set { Time = DateTimeOffset.Parse(value).DateTime; }
}

Or, if you really often auto-generate those classes, you can introduce wrappers for them, which will transparently convert DateTime to UTC.
