首先,這裏是代碼,結果是什麼期待: 代碼1: using System;
namespace ConsoleApplication11
{
class DerivedClass : Base
{
public new void Run()
{
Console.WriteLine("Derived class");
}
我有兩個類,Sensor和Channel。通過在通道中「插入」傳感器來使用它們(即,使用Sensor實例將Channel的屬性設置爲Sensor)。然後,當你調用AddSamples在Channel與非空傳感器的Sensor.WhenNewSamples用戶會被告知: public abstract class Channel

import CoreData
extension Media {
@NSManaged public var imageString: String?
}
