Imports IWshRuntimeLibrary '引用:Windows Script Host Object Model
Public Class LnkFileClass

End Sub
Public Function GetLnkFileInfo(ByVal LnkFilePath As String) As String
Dim iPos As Integer

通过字节搜索获得路径也不慢么:

Public Class LnkFileExePath
Private m_Stream As FileStream
Private m_Reader As BinaryReader
Public Sub New()
End Sub
Public Function GetLnkFileInfo(ByVal LnkFile As String) As String
GetLnkFileInfo = ""
Dim tmp As String = ""
Dim i As Integer = 0
Dim iFilePath As String = ""
Dim iPos As Integer = 0
Dim n As Integer = 0
Try
m_Stream = New FileStream(LnkFile, FileMode.Open, FileAccess.Read)
m_Reader = New BinaryReader(m_Stream)
Catch ex As Exception
Return ""
End Try
Try
Dim k As Integer = m_Reader.BaseStream.Length
For i = 260 To k
m_Reader.BaseStream.Seek(i, SeekOrigin.Begin)
iFilePath = Nextchars(1024, m_Reader)
If iFilePath.Substring(1, 2) = ":/" Then
iFilePath = iFilePath.Substring(0, InStr(iFilePath, Chr(0)) - 1)
If iFilePath.Length > 5 Then
If iFilePath.Substring(iFilePath.Length - 4) = ".exe" Then
m_Reader.Close()
m_Stream.Close()
Debug.WriteLine(i & " " & iFilePath)
Return iFilePath
End If
End If
End If
Next
Catch ex As Exception
m_Reader.Close()
m_Stream.Close()
Return ""
End Try
m_Reader.Close()
m_Stream.Close()
Return ""
End Function
Private Function Nextchars(ByVal Num As Integer, ByVal reader As BinaryReader) As String
Dim ch() As Byte
ReDim ch(Num - 1)
reader.Read(ch, 0, ch.Length)
Return Encoding.Default.GetString(ch, 0, ch.Length)
End Function
End Class
