Stream vs byte[]

 

當檔案讀取或Socket讀取資料時，經常使用Stream 類別。若要將Stream 直接轉換成 String 似乎有些困難，經過一層 [] 就可輕鬆完成

/// <summary>

/// 將 Byte[] 轉為 Stream

/// </summary>

/// <returns>Stream</returns>

public static Stream BytesToStream(byte[] bytes)

{

     Stream stream = new MemoryStream(bytes);

     return stream;

}

public static Stream BytesToStream(byte[] bytes, int Length)

{

      Stream stream = new MemoryStream(bytes, 0, Length);

      return stream;

}

/// <summary>

/// 將 Stream 轉為 Byte[]

/// </summary>

public static byte[] StreamToBytes(Stream stream)

{

      byte[] bytes = new byte[stream.Length];

      stream.Read(bytes, 0, bytes.Length);

      /*將 stream 指針指向開頭*/

      stream.Seek(0, SeekOrigin.Begin);

      return bytes;

}
