当我想在“return (byte)SaleMode.ToPost;”行中使用“SetSaleMode”时，我有一个包含这些字段和这些静态方法的类 发生此错误，有人可以帮助我吗？

这些是我的代码：

公共枚举 SaleMode:byte { ToPost = 0, Downloadable = 1, DownloadableAndFreeTrial = 2, SourceSiteSale = 3 };
公共枚举 FilePriceMode { ProductFile = 0, Free = 1, FreeTrial = 2 };



公共类 ProductDAL : BaseDAL
{


#region fields
public Int64 ID { get; set; }
public string Name { get; set; }
public Int64 Price { get; set; }
public bool Private { get; set; }
public Int64 ProductType { get; set; }
public string Notes { get; set; }
public string Image { get; set; }

您有一个名为SaleModeenum的属性SaleMode。

当您SaleMode在类中使用时，您指的是属性，而不是枚举。该属性会在整个范围内隐藏枚举。

我建议您重命名该属性，使其不会与枚举冲突。
