如何使用BinaryReader读取midi文件(格式规范为here

我正在使用vb.net,但我愿意看到其他代码(大多数只是C#,我可以转换它)。我正在做一个大项目,这有点像一个速度爆炸。

这是我目前的代码:

Private Function convertCharArrayToString(ByVal chars() As Char) As String
    Dim tReturn As String = ""
    For Each v As Char In chars
        tReturn &= v
    Next
    Return tReturn
End Function

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    midiStatus = "Reading..."
    Dim midiStream As New StreamReader(midiFile)
    Dim nBR As New BinaryReader(midiStream.BaseStream)
    midiStatus = "Validating Midi File..."
    Dim HeaderA As String = convertCharArrayToString(nBR.ReadChars(4))
    If Not HeaderA = "MThd" Then Return
    Dim HeaderB() As Byte = nBR.ReadBytes(4)
    'Get Track Type
    midiStatus = "Reading Header Data..."
    Dim TrackType1 As Integer = nBR.ReadInt16()
    Dim TrackType2 As Integer = nBR.ReadInt16()
    MsgBox(TrackType1 & TrackType2)

End Sub

当我开始阅读实际的标题数据时,一切正常。关于我如何继续,我完全迷失了。任何帮助或代码示例都会很好!

将解码逻辑写入类中,而不是直接在GUI中编写。

定义MIDI标头的结构,然后使用类似this的设置来设置它。
