Casting object to List<(Enum, string)> issue

Asked 2021-May-16 at 07:34

I am creating a converter by implementing IMultiValueConverter with *Convert(object[] values, Type targetType, object parameter, CultureInfo culture)

I am passing a List<(SomeEnumType, string)> tuple.

via MultiBinding and on the converter side I would like to cast but it throws a casting error.

I tried : var result = (List<(Enum, string)>)values[1];

but I got this casting issue:

'Unable to cast object of type 'System.Collections.Generic.List1[System.ValueTuple2[Vasco.Basics.Contracts.CoreConfigurations.Enums.ApplicationType,System.String]]' to type 'System.Collections.Generic.List1[System.ValueTuple2[System.Enum,System.String]]'.'

It is strange because If I pass only one element of SomeEnumType and try to case like (Enum)values[1] casting works well.

When I pass a List and try to cast like (List)values[1] does not work already.

Thank you in advance!

When I pass a List and try to cast like (List)values1 does not work already.

You generally aren't allowed to cast generic collections like List or IEnumerable to other types. This comes down to how C# and the compiler handle generics and something called Covariance and contravariance. This is an incredible complicated topic, at least for me, so I won't bogg you down with the fine details.

Consider the following situation.

Symfony DoctrineFixturesBundle issue with dependencies

Asked 2020-Dec-21 at 14:17

I have a Fixture class which depends on 2 other classes. According to documentation, for doing so I need to implement the DependentFixtureInterface, and add a method getDependencies() returning them. And I did, however I'm getting an SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'comunidad_autonoma_id' cannot be null error. I already cleared and warmed up the cache, several times, but the error persists. What am I missing?

Here's my Fixture class...

The Doctrine error explicitly said that there is an Integrity constraint violation. The column comunidad_autonoma_id cannot be null. Either try to update you entity Provincia to mark the field omunidadAutonoma as nullable or check your dataset array to make sure that each comunidad_autonoma has a corresponding record in your database.

QUESTION

Can you compare the output of a scalar function with a scalar in a check statement? SQL

Asked 2020-Dec-01 at 18:50

I want to compare the output of a scalar function with a scalar value in a CHECK statement when creating a table, but it doesn't seem to do the right comparisons. I want the check statement to be "checked" if the scalar function returns 1. Is there any way to do this? (The function is called in the last check statement)

The statement runs successfully, and if I run the function out of the CHECK function it returns the right values (0 or 1), but when I insert data that satisfies 1 in the function returned value, errors are returned. This is my code and what I've tried,

Marx,

I see no error with the CHECK statement in your table. See the dbfiddle here; it is working as intended, because the value you are trying to INSERT violates the CHECK statement and will not work.

If you click the link and scroll down, you see that based on the data you provided, there is no way for the function to return 1 for some of these rows. Namely, here is one example that fails:
