ユーザーがドロップダウンで指定された列を検索できるようにする検索機能を作成しようとしています。検索を機能させることができましたが、特定の列と含むメソッドを使用することによってのみです。誰でも助けることができますか？
以下にコントローラーとビューを含めました。他のコードが必要な場合はお知らせください。お時間をいただきありがとうございます。
これは、特定の列の代わりにドロップダウンを使用して検索するために変更する必要があるコードであることはほぼ間違いありません。
if (!String.IsNullOrEmpty(searchString))

IAMP = IAMP.Where(p => p.PA.ToUpper().Contains(searchString.ToUpper()));
