Dynamically load collection manager with an object in different namespace

Apr 26 2009 5:17 PM

Based on the code below, how do I dynamically create a Gake.Orchard.Business.PageContent object in the Gake.Data.Base.DataCollection.Retrieve method?

Below is "working" code; however, I don't think I should be explicitly passing in "typeof(typePageContent)", in order to get it to work. I believe I should be able to get that from "typDataObject". The syntax that I'd like to use, is commented out; however, the line "typDataObject typObj = new typDataObject();" created Gake.Orchard.Data.PageContent, when I need it to create Gake.Orchard.Business.PageContent.

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

PageContentCollection pcc = new PageContentCollection(2,this.GetType().Name);

//...

}

}

namespace Gake.Orchard.Business

{

public class PageContentCollection : Gake.Orchard.Data.PageContentCollection<PageContent>

{

//...

}

}

namespace Gake.Orchard.Data

{

public abstract class PageContentCollection<typPageContent> : Gake.Data.Base.DataCollection<PageContent> where typPageContent : PageContent

{

public PageContentCollection(int Panel, string Page)

{

//DataResult result = base.Retrieve("Panel = @1 and Page = @2", Panel, Page);

DataResult result = base.Retrieve(typeof(typPageContent), "Panel = @1 and Page = @2", Panel, Page);

//...

}

}

}

namespace Gake.Data.Base

{

public abstract class DataCollection<typDataObject> : CollectionBase where typDataObject : DataObject//, new()

{

//public DataResult Retrieve(string Conditions, params object[] Values)

public DataResult Retrieve(Type TypeOfChild, string Conditions, params object[] Values)

{

//...

//typDataObject typObj = new typDataObject();

Object objChild = Activator.CreateInstance(TypeOfChild);

//...

}

}

}
