轉換UnmanagedMemoryStream到字節數組

Question

就這麼簡單，我怎麼能在VBNET轉換一個UnmanagedMemoryStream到字節數組：

Dim bytes() As Byte = My.Resources.AudioFile 

例外：

Value of type 'System.IO.UnmanagedMemoryStream' cannot be converted to '1-dimensional array of Byte'. 

Answer 1

您可以直接轉換System.IO.MemoryStream爲Byte()陣列，通過使用：

Dim myMemStream As New System.IO.MemoryStream 
My.Resources.AudioFile.CopyTo(myMemStream) 
Dim myBytes() As Byte = myMemStream.ToArray 

Answer 2

試試這種方法。我還沒有驗證它，但它遵循類似於MSDN的文章，並進行了一些修改。 http://msdn.microsoft.com/en-us/library/system.io.unmanagedmemorystream.aspx

Dim audioBytes() as Byte 
Dim audioStreamReader As System.IO.UnmanagedMemoryStream = CType(My.Resources.AudioFile, System.IO.UnmanagedMemoryStream) 
Dim length As Long = audioStreamReader.Length 
audioStreamReader.Position = 0 
audioStreamReader.Read(bytes, 0, length); 
'At this point, audioBytes contains the data.
