C# 从匿名类型中选择字符串列表

Question

我有以下 LINQ，我需要将结果作为列表返回，但我收到错误:

Cannot implicitly convert type System.Collections.Generic.IEnumerable<<anonymous type: string emis>> to System.Collections.Generic.List<string>. An explicit conversion exists (are you missing a cast?)

如何返回字符串列表？

List<string> emisList = (
    from p in subproductTypeyProduct
    join q in dbEntitiesParams.PARAM_Rule
    on new { p.ProductType, p.SubProductTypeCode }
    equals new { ProductType = q.ProductTypeCode, SubProductTypeCode = q.SubProductCode }
    select new { q.emis });

Answer 1

无需投影匿名类型。只是简单的字符串。将 select new { q.emis } 替换为 select q.emis。
