vb.net - VB - 如何读取和写入二进制文件？

Question

如何从任何文件中读取原始字节数组...

 Dim bytes() as Byte

..然后将该字节数组写回新文件？

我需要它作为一个字节数组来做一些处理。

我目前正在使用:

阅读

 Dim fInfo As New FileInfo(dataPath)
 Dim numBytes As Long = fInfo.Length
 Dim fsAs New FileStream(dataPath, FileMode.Open, FileAccess.Read)
 Dim br As New BinaryReader(fs)
 Dim bytes As Byte() = br.ReadBytes(CInt(numBytes))
 br.Close()
 fs.Close()

来写

Dim fs As System.IO.FileStream
fs = New System.IO.FileStream(outpath, System.IO.FileMode.Create)
fs.Write(bytes, 0, bytes.Length)
fs.Close()

Answer 1

Dim data() as Byte = File.ReadAllBytes(path1)
File.WriteAllBytes(path2, data)
