C# ASP MVC API IEnumerable JSON数组缺少键名

感谢您的重播，但我遇到了以下错误：无法将类型“AnonymousType1”隐式转换为“System.Collections.Generic.IEnumerableOops”，我的错误。您应该创建一个类似于public类InventoryData{public IEnumerable Inventory{get；set；}}的类，并更改返回此类型的方法：returnnewinventorydata{Inventory=…}；感谢您的重播，但我遇到了以下错误：无法将类型“AnonymousType1”隐式转换为“System.Collections.Generic.IEnumerableOops”，我的错误。您应该创建一个类似于public类InventoryData{public IEnumerable Inventory{get；set；}}的类，并更改返回此类型的方法：returnnewinventorydata{Inventory=…}；
