「return (byte)SaleMode.ToPost;」行で「SetSaleMode」を使用したい場合、これらのフィールドとこれらの静的メソッドを持つクラスがあります。このエラーが発生しました。誰か助けてくれますか?
これらは私のコードです:
public enum SaleMode:byte { ToPost = 0、ダウンロード可能 = 1、DownloadableAndFreeTrial = 2、SourceSiteSale = 3 }; public enum FilePriceMode { ProductFile = 0、Free = 1、FreeTrial = 2 };パブリック クラス ProductDAL : BaseDAL {
