39                 Stream 表示“流”(這個bai概念在計算機中非常常見,題主可以自行搜索相關資料),本質上是一種字節序列。說穿了,計算機只認識0和1,那麼這麼豐富多彩的文本、音樂、視頻,歸根結底都是轉換成字節存儲在內存與硬盤中的。
40                 Stream 對象有一個屬性 Length,表示這個流的長度;還有一個屬性 Position,表示這個流當前的位置。
41                 Stream.Read(byte[] array, int offset, int count);
42                 array 表示緩衝區;offset 表示從流的當前位置(也就上面說的 Position)偏移多少個字節開始讀;count 表示讀取多少個字節。
43                 該方法返回的是實際上讀取了多少個字節(永遠小於等於 count),如果該值等於 0,說明已經到流的末尾了。讀取之後,這個流的 Position 就會發生變化。
44                 爲什麼要緩衝區?因爲一個流很可能非常大,一次性的加載是不現實的,所以需要分塊來讀取,存儲每個分塊的這個字節數組就叫做“緩衝區”。
