Question

我已经四处寻找但找不到解决方案。这个Reading only x number of bytes from file in VB.NET似乎指向了正确的方向，但我不能让它给我需要的HEX信息......

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
    If (OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK) Then
        TextBox1.Text = OpenFileDialog1.FileName
    End If
End Sub


Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim filename = TextBox1.Text
    Dim arraySize = 5
    Dim buffer() As Byte = New Byte(arraySize) {}
    Using fs As New System.IO.FileStream(filename, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.None)
        fs.Read(buffer, 0, buffer.Length)
    End Using
'this solves it!
 Dim hextottext As String = System.Text.Encoding.UTF8.GetString(buffer)
    MsgBox(hextottext)

End Sub

这就是我正在使用的代码 - 当它单步执行时，

fs = System.IO.Filestream

我不明白为什么。

基本上我想读取前6个字节，将它们转换为十六进制的可读文本，这是一个.iso映像文件。

感谢chr功能提示，但我在搜索过程中发现了这一点！

从.iso文件中读取6个字节
