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)

Next

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

Next

Next

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，
