This is a known issue https://github.com/dotnet/aspnetcore/issues/13619

但是 解决 我在一个项目中所做的工作是

public class DateTimePickerComponent : DateTimePickerComponent<DateTime?> { } // default Type value

public class DateTimePickerComponent<T> : BaseSubComponent { .... } // all business here

并且在组件 I 中继承自

@inherits DateTimePickerComponent  // default type will be DateTime?
@inherits DateTimePickerComponent<DateTime> // this also work
