如果圖像是問題，我會建議以不同的方式做。您的剃刀視圖可能不應負責淘洗服務器以查找圖像;考慮通過模型或ViewData將該信息推入視圖。

另外，爲什麼你將@"\\"傳遞給Path.Combine？您正在向路徑添加雙斜槓。讓Path.Combine來處理這個問題。我認爲這可能是你的主要問題。請執行下列操作之一：

string itemImagesFolderPath = Path.Combine(imagesFolderPath, ImageType.Item + @"\" + auction.Auction.InventoryReference); 

，或者更優選

string itemImagesFolderPath = Path.Combine(imagesFolderPath, ImageType.Item, auction.Auction.InventoryReference);
