Object mapping with LINQ and SubSonic
- by Jeremy Seekamp
I'm building a small project with SubSonic 3.0.0.3 ActiveRecord and I'm running into an issue I can't seem to get past.
Here is the LINQ query:
var result = from r in Release.All()
let i = Install.All().Count(x => x.ReleaseId == r.Id)
where r.ProductId == productId
select new ReleaseInfo
{
NumberOfInstalls = i,
Release = new Release
{
Id = r.Id,
ProductId = r.ProductId,
ReleaseNumber = r.ReleaseNumber,
RevisionNumber = r.RevisionNumber,
ReleaseDate = r.ReleaseDate,
ReleasedBy = r.ReleasedBy
}
};
The ReleaseInfo object is a custom class and looks like this:
public class ReleaseInfo
{
public Release Release { get; set; }
public int NumberOfInstalls { get; set; }
}
Release and Install are classes generated by SubSonic.
When I do a watch on result, the Release property is null.
If I make this a simpler query and watch result, the value is not null.
var result = from r in Release.All()
let i = Install.All().Count(x => x.ReleaseId == r.Id)
where r.ProductId == productId
select new Release
{
Id = r.Id,
ProductId = r.ProductId,
ReleaseNumber = r.ReleaseNumber,
RevisionNumber = r.RevisionNumber,
ReleaseDate = r.ReleaseDate,
ReleasedBy = r.ReleasedBy
};
Is this an issue with my LINQ query or a limitation of SubSonic?
