读写文件的有关问题

读写文件的问题
读取任意一个文件，然后以文本输出，输出格式类似如下：
FF FD ED 00 13 24 00 15 AD AE EE CD FF FF FF FF
FF FD ED 00 13 24 00 15 AD AE EE CD FF FF FF FF
FF FD ED 00 13 24 00 15 AD AE EE CD FF FF FF FF
这样的16进制，我该怎样写这段代码

[解决办法]
读取文件流到byte[]数组，再输出

VB.NET code

Dim fs As New System.IO.FileStream("文件路径", System.IO.FileMode.Open)Dim buffer As Byte()Dim read As IntegerDim offset As IntegerDim remaining As Integerbuffer = New Byte(fs.Length - 1) {}offset = 0remaining = buffer.LengthWhile remaining > 0    read = fs.Read(buffer, offset, remaining)    remaining -= read    offset += readEnd Whilefs.Close()fs.Dispose()Dim sb As New System.Text.StringBuilder()For i As Integer = 0 To buffer.Length - 1    sb.AppendFormat("{0:X2} ", buffer(i))NextDim output As String = sb.ToString()
[解决办法]
读写文件是基本知识，自己找资料学啊
VB.NET code
Dim sw As System.IO.StreamWritersw = System.IO.File.CreateText("C:\Users\Cloveaf\Desktop\123.txt")sw.Write(output)sw.Close()sw.Dispose()
