关于播放器中的功能（歌词同步），急求VB.NET代码！！

思路很简单可以定义一个结构LyricStructure Lyric

Dim Time As Single

Dim Content As String

End Structure声明一个列表 Private Lyrics As New List(Of Lyric)然后以文本方式把歌词文件读入一个变量并对它进行分析分别把时间和歌词内容存入一个Lyric，并加入Lyrics中。代码如下：（假设歌曲文件的路径为path）Dim LrcPath As String== IO.Path.GetDirectoryName(cPath) "/" IO.Path.GetFileNameWithoutExtension(cPath) ".lrc"If IO.File.Exists(LrcPath= True Then AnalysisLyric() Private Sub AnalysisLyric()

Lyrics.Clear() '先清空列表

Dim tm As Byte

Dim sr As New IO.StreamReader(LrcPath, System.Text.Encoding.Default) '读取歌词文件

Do While sr.EndOfStream = False '判断是否处于文件流末尾

Dim tmpStr As String = sr.ReadLine '读取一行

If tmpStr.Length 5 Then Continue Do '长度小于5则跳过，进行下一次循环

Select Case Mid(tmpStr, 2, 2) '判断第2-3个字符因为歌词里的注释都是[ti:***]类似的结构

Case "ti"

lTitle = Mid(tmpStr, 5, tmpStr.Length - 5)

Case "ar"

lArtist = Mid(tmpStr, 5, tmpStr.Length - 5)

Case "al"

lAlbum = Mid(tmpStr, 5, tmpStr.Length - 5)

Case "by"

lAuthor = Mid(tmpStr, 5, tmpStr.Length - 5)

Case Else '如果不为以上的内容则为歌词正文，进行以下操作

If Not Mid(tmpStr, 1, 6) Like "?##:##" Then Continue Do

Dim time(-1) As String '因为有时歌词是以[00:00.00][00:00.00]**** 这样歌词把多个时间存放在一起的，所以定义一个数组来存放歌词

Do '因为不确定时间的个数，所以此处必须循环判断

tm = InStr(tmpStr, "]") '因为歌词时间有时是[00:00.00]形式，有时是[00:00]形式，所以不能单纯的截取第几个字符，我是根据查找']'字符来进行判断的

ReDim Preserve time(time.GetUpperBound(0) + 1) 为time数组重新分配大小

time(time.GetUpperBound(0)) = Mid(tmpStr, 1, tm) 'time.GetUpperBound(0)返回数组的第一维的最大下标

tmpStr = IIf(tmpStr.Length = tm, " ", Mid(tmpStr, tm + 1)) '歌词内容

Loop While Mid(tmpStr, 1, 6) Like "?##:##" '如果截取剩下的部分依然匹配的话继续循环

For Each t In time '为每个时间都创建一个Lyric变量

Dim ln As Lyric

ln.Time = SwitchTime(Mid(t, 2, t.Length - 2))

ln.Content = tmpStr

Lyrics.Add(ln)

End Select

Loop

sr.Close() 关闭流

Sort() '把所有Lyric按时间顺序排序

End Sub Private Function SwitchTime(ByVal time As String) As Single ‘这个函数是用来把00:00.00格式的时间转化成以秒数显示的数值

Dim tm As Single

Dim minute As Single = Val(Mid(time, 1, 2))

Dim second As Single = Val(Mid(time, 4, 5))

tm = minute * 60 + second

Return tm

End Function Private Sub Sort()

For i = 0 To Lyrics.Count - 2

For j = i To Lyrics.Count - 1

If Lyrics(i).Time Lyrics(j).Time Then

Dim tm As Lyric = Lyrics(i)

Lyrics(i) = Lyrics(j)

Lyrics(j) = tm

End If

End Sub 接下来是显示歌词的问题了，只要有每句歌词和对应的时间，那么问题就好办了。你可以用Windows Media Player控件返回的时间和每句歌词的时间做比较，来判断应该显示那一句。代码是很久前写的，那时没加注释，都是刚刚加上去的哟，你可以根据你的实际情况自己修改，有什么不懂的地方可以继续问我哈~~

VB.NET 怎么同步显示lrc歌词？？

可以稍微改下，预读两句歌词的时间范围，时间大于第一句的起始点，小于第二句的起始点，那么显示第一句，
