Using List<T> in class

[dqrest]

Hi!
I have 2 questions.
I have Devart.Data.Linq 4.4.697.0, Devart.Data.Oracle.Linq 4.4.697.0, Devart.Data.Oracle. 8.4.359.0 and use MS VS 2013 Ultimate.

The first question.
Can I use List<T> in the class which is formed in linq expressions.

For example,

var res = from c in All.SysFilterCriterions
where c.FilterNo == filterNo select new MyClass { No = c.FilterNo, myList = new List<int>() };

public class MyClass
{
public long No;
List<int> myList;
}

Can I use List<T> in MyClass.

The second question.
Because I use a Devart.Data.Linq 4.4.697.0, Devart.Data.Oracle.Linq 4.4.697.0, Devart.Data.Oracle. 8.4.359.0, I should use Devart.Data.Linq.Mapping instead of System.Data.Linq.Mapping to map tables from database. In this case, should I use Devart.Data instead of System.Data?

At last, I'd like to ask the third question.

Is System.Linq.Dynamic compatible to Devart.Data.Linq 4.4.697.0, i.e. can I get some problems with mapping of table and executing linq expressions in code?

Can I construct a dynamic query in LINQ with System.Linq.Dynamic and Devart.Data.Linq 4.4.697.0 ?

The should be no problems with the code snippet you have specified. Did you encounter any error with this? If yes, please specify more details.

No, you should use Devart.Data additionally to System.Data. However, you should remove all occurrences of System.Data.Linq.
LinqConnect uses its own classes since version 4.0 (since this version the references to System.Data.Linq are removed, LinqConnect uses only its own classes; there were a lot of fixes/improvements since this version, including the code generation, compiled query cache, etc.).
For correct work with LinqConnect it is necessary to use Devart.Data.Linq instead of System.Data.Linq.

Yes, System.Linq.Dynamic can be used with Devart.Data.Linq. If you encounter any issues with this, feel free to contact us.
