我有以下一段代码,但我不知道?
构造中的含义。
它在做什么?
myObj_Request r = new myObj_Request(); //instantiate intial object
r.Channels = new ChannelSequence(); //initial object has another object in channels
r.Channels.ChannelType = new ChannelType?[5] { .. } // ok so we have 5 channeltypes...
// but that ? infront of [5] ?
