vb.net - VB.Net 十六进制值中的反向字节

Question

    Private Sub LRbtn_Click(sender As Object, e As EventArgs) Handles LRbtn.Click
    OpenFileDialog1.Title = "Please Select a File"
    OpenFileDialog1.ShowDialog()
    Dim filename As String = OpenFileDialog1.FileName
    Dim fs As FileStream = New FileStream(filename, FileMode.Open)
    Dim br As BinaryReader = New BinaryReader(fs)
    br.BaseStream.Seek(verOffset, SeekOrigin.Begin)
    a = br.ReadInt32()
    verLabel.Text = hex2ascii(Hex(a))
    br.Close()
    fs.Close()

End Sub

我正在打开并二进制读取一个文件，然后我在给定地址读取 4 个字节。

因此，例如，变量a可能是1163022402转换为十六进制的变量是45,52,50,42

转换a为十六进制后，我需要反转字节以获得42,50,52,45

我是VB的新手，我正在学习它，我该怎么办？谢谢！

如果您需要 32 位，只需读取 4 个字节就可以使用br.ReadBytes，那么您可以随意订购它们
