DateTime came back from JavaScript as a V8ScriptObject. Why?

[AnsisMalins]

The following unit test fails because result is not a DateTime but a V8ScriptObject. But why? ClearScript has code specifically for DateTime.

[Test]
public void GetDateTime()
{
    var csDate = DateTime.Parse("2010-10-10T20:30:00Z");
    
    hostObject.GetNamedProperty = (StdString name, V8Value value) =>
    {
        Assert.That(name.Equals("getDateTime"));
        value.SetDateTime(csDate);
    };
    
    object result = engine.Evaluate(@"{
        let csDate = hostObject.getDateTime;
        assert(csDate instanceof Date); // <== succeeds
        let jsDate = new Date('2010-10-10T20:30:00Z');
        assert(csDate.getTime() === jsDate.getTime()); // <== succeeds
        csDate;
    }");

    Assert.That(result is DateTime dateTime && dateTime == csDate); // <== fails
}

Hi @AnsisMalins,

The JavaScript code that you're passing to Evaluate doesn't define value but returns it. What is it?

Thanks!

Oops, typo. I mean to write csDate; there.

[AnsisMalins]

I mean, I renamed the variables for the post, and of course I missed one. Sorry for the confusion.

Thanks. Since csDate instanceof Date is true, we can assume that csDate is a JavaScript Date instance. For such an object to be automatically converted to DateTime, you must construct the engine with V8ScriptEngineFlags.EnableDateTimeConversion.
