Is there a ZonedDateTime (Java) in .Net?

问题

The best equivalent I've found is the combination of a DateTimeOffset + TimeZoneInfo. Is that the best approach, create a structure that contains both of these classes and insure they stay consistent?

回答1:

No, there is not a built-in type similar to ZonedDateTime in the .NET base class library.

As others pointed out, if you're looking for a temporal model similar to Java's Joda Time or java.time, then consider using Noda Time. It has a ZonedDateTime structure.

If you don't want to use Noda Time, and you really need a single object containing date time offset and time zone, then your suggested approach of a struct with DateTimeOffset and TimeZoneInfo fields makes sense. Here are some additional tips:

• It's important you design this as an immutable struct, in otherwords - take input only from the constructor. Expose only property getters over the fields. Don't expose the fields directly, and don't provide setters on the properties.

• Be aware of how you want to handle situations where the offset of a DateTimeOffset is not the correct offset for the given time zone. You may want to adjust it, or you may want to throw an exception.

• You may need to provide custom serialization for your struct, and you may need to deconstruct it if saving to a database. In either scenario, keep only the string Id of the TimeZoneInfo component. Don't try to serialize or store the entire object.

That said - you might want to reconsider if you need such an object. In many cases, simply using the DateTimeOffset and TimeZoneInfo separately are sufficient.
