On first glance- this all looks good to me- is there anything actually missing?

chucker · 2021-07-12T10:33:45Z

I just used this in a project and, superficially, it seems to work quite well.

(edit)

Actually, I think there's a problem when a value is nullable. I have this type:

public record CellularDataUsage(UnitsNet.Information Remaining, UnitsNet.Information? Incremental, UnitsNet.Information Total);

And if incremental is ever null, that seems to cause exceptions when trying to deserialize.

Thanks for reporting @chucker. Are you able to debug where it goes wrong and what improvements can be made?

chucker · 2021-07-12T11:33:41Z

When serializing, I sometimes(?) get a cycle exception:

public class UnitsNet905
{
    public UnitsNet.Information DataUsage { get; set; }
}

// elsewhere

var myDataUsage = new UnitsNet905
{
    DataUsage = UnitsNet.Information.FromGibibytes(15)
};

string json = "";

try
{
    json = System.Text.Json.JsonSerializer.Serialize(myDataUsage);
}
catch (Exception ex)
{ }

var newMyDataUsage = System.Text.Json.JsonSerializer.Deserialize<UnitsNet905>(json);

It throws:

    System.Text.Json.JsonException: A possible object cycle was detected. This can either be due to a cycle or if the object depth is larger than the maximum allowed depth of 64. Consider using ReferenceHandler.Preserve on JsonSerializerOptions to support cycles.

I may be serializing incorrectly, but the same does work if the property is a double.

In addition, if a property is nullable and the value is in fact null, deserializing fails:

The type is:

If I change the type to either of these two, the exception does not occur:

public record CellularDataUsage(UnitsNet.Information Remaining, UnitsNet.Information Incremental, UnitsNet.Information Total);

@chucker Thanks a lot for documenting. Are you able to figure out what changes are needed to make this work?
Or maybe @rgomez90 recognizes what is happening?

Doesn’t a second PR count as “recent activity”?

rgomez90 · 2021-09-20T01:29:17Z

Sorry for the inactivity. I was "out-of order" for a while.

I would take again a look at this.

Now, there is also #966 by @akaegi which "fixes" what appears to be wrong here.

@angularsen should we close this PR and continue working in #966 or should I merge #996's changes here?

rgomez90 · 2021-09-20T01:31:13Z

@chucker It seems like referencing issues does not count as an activity in a PR/issue.

angularsen · 2021-09-20T05:08:18Z

Hi all,

A single PR would do :-) If it's #905 or #966, doesn't matter to me.

For your information, there is also #907 that adds [DataContract] to quantities and it propose a new serialization schema to support both double and decimal with a single field.

It is still work in progress, but please read the summary comment here:
#907 (comment)

@rgomez90 @chucker @lipchev

angularsen · 2021-10-17T23:00:39Z

FYI, #972 was merged.

Also, there was some discussion that reveals our current JSON schema is maybe not optimal.
ValueType and ValueString properties are likely not necessary in order to preserve decimal precision:
