問題：

解析が0アイテムを返すたびに。linq ブロック全体が一度に通過するため、デバッグできません。List Count は常に =0 を示しています。

式から結果が得られないのは正常です。

from e in (LoadXmlStuff()).Root.Elements("Horizon-Export")

XML の場合、ルートの子孫で<Horizon-Export> はなく、ルートであるためです。

<Horizon-Export>これは、XML にはルートが 1 つしかないため、XML に複数のタグが存在できないことも意味します。より多くのタグを持つ唯一の可能性は、それらを別のタグでラップすることであり、それがルートになります。
