Reading all components from folder and subfolder

I am working on Tridon 2009 using .NET Templating C# 2.0

I need to read all the components from folders and its subfolder.

If in my code I write:

OrganizationalItem imageFolder = 
    (OrganizationalItem)m_Engine.GetObject(comp.OrganizationalItem.Id);

I am able to read all the components in subfolder from the place where indicator component is present, but I am not able to read other components present in the folder where indicator is present.

But If I write

OrganizationalItem imageFolder = (OrganizationalItem)m_Engine.GetObject(
                                comp.OrganizationalItem.OrganizationalItem.Id);

then I am able to read only folder where indicator component is present.

Below is my code.

XmlDocument doc = xBase.createNewXmlDocRoot("ImageLibrary");
XmlElement root = doc.DocumentElement;


Filter filter = new Filter();
Component comp = this.GetComponent();

filter.Conditions["ItemType"] = ItemType.Folder;
filter.Conditions["Recursive"] = "true";

OrganizationalItem imageFolder = 
       (OrganizationalItem)m_Engine.GetObject(comp.OrganizationalItem.Id);            
XmlElement itemList = imageFolder.GetListItems(filter);

foreach (XmlElement itemImg in itemList)
{
    filter.Conditions["ItemType"] = ItemType.Component;
    filter.Conditions["BasedOnSchema"] = comp.Schema.Id;

    OrganizationalItem imgFolder = 
       (OrganizationalItem)m_Engine.GetObject(itemImg.GetAttribute("ID")
       .ToString());
    XmlElement imageLibs = imgFolder.GetListItems(filter);

    doc = this.createImageNodes(imageLibs, doc, filter, comp);
    foreach (XmlElement imglib in imageLibsList)
    {
        XmlElement imageroot = doc.CreateElement("Image");
        XmlElement uploadeddateNode = doc.CreateElement("DateUploaded");
        Component imgComp =    
                (Component)m_Engine.GetObject(imglib.GetAttribute("ID"));
    }
}

Please suggest.

Solution

I see a lot of superfluous code on your snippet regarding the question "Reading all components from folder and subfolder"

But answering the question itself, when you are doing:

OrganizationalItem imageFolder = (OrganizationalItem)m_Engine.GetObject(comp.OrganizationalItem.Id);

Your are not being able to read components present on that folder, because you have previously set the filter to folders only on the following line:

filter.Conditions["ItemType"] = ItemType.Folder;

Solution:

If you want to retrieve all components on the "indicator component" folder and below, you need to set the filter on your first search as following:

filter.Conditions["Recursive"] = "true";
filter.Conditions["ItemType"] = ItemType.Component;
filter.Conditions["BasedOnSchema"] = comp.Schema.Id;

And perform the search:

OrganizationalItem imageFolder = (OrganizationalItem)m_Engine.GetObject(comp.OrganizationalItem.Id);            
XmlElement itemList = imageFolder.GetListItems(filter);
