To read
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()
To write
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()
