C#的byte[]和AS3中的ByteArray都是字節數組.但是明顯的AS3的ByteArray更加好用一些.因為在ByteArray當中有一個position屬性,可以讀取相應的字節后,自動指向下一個沒有讀取的字節的index.這樣你永遠不用自己再建一個index來手動的處理這件事情了.當然,ByteArray還有其他的一些方法和屬性,是byte[]沒有的.我這里強調,并非貶低C#,只是在這一塊,需要做一些多余的事情,顯得相當的繁瑣.為此我封裝了一個類庫,核心類 BytesDecode 如下:

}本類可以解析: 基礎數據 , 基礎數據一維數組 , 基礎數據二維數組
在此額外奉上 基礎數組2byte[]
//將基元數據類型數組轉換成字節數組
public static byte[] ToBytes<T>(T[] array) where T : struct
{
if (array == null)
{
throw new ArgumentNullException("array");
}
var bytes = new byte[Buffer.ByteLength(array)];

}補充說明:
這個包是為Unity開發的.當然要知道它支持FrameWork的版本號了. 在PlayerSettings當中.關于如何使用FrameWork2.0來編譯類庫,自己Google
