您可以使用params关键字的委托？
我想定义一个委托，它需要几个日期，数目不详的其他参数（使用params关键字），并返回对象列表;
I'd like to define a delegate that takes a couple of dates, an unknown number of other parameters (using the params keyword), and that returns a list of objects;
Func<DateTime, DateTime, params int[], List<object>>
Visual Studio中不喜欢这让我觉得这个语法是不允许的。谁能告诉我为什么？
Visual Studio doesn't like the syntax which is making me think this isn't allowed. Can anyone tell me why?
您不能有一个泛型类型参数自定义属性（CLI不会允许它），以及C＃编译器实现的 PARAMS 关键字 System.ParamArrayAttribute 上的相关方法的参数。
You can't have custom attributes on a generic type argument (the CLI doesn't permit it), and the C# compiler implements the params keyword by emitting the System.ParamArrayAttribute on the relevant method parameter.
这阻止你使用它与System.Func＆LT; ...＆GT;泛型委托，但你总是可以创建一个不使用自己的委托类型 PARAMS 。
This stops you from using it with the System.Func<...> generic delegates, but you can always create your own delegate type that does use params.
