Dim ipFile As String = e.ProjectPath & "ip.txt"
If e.Name = "销售数据" Then
    If Filesys.FileExists(ipFile) Then
        Dim ip As String = FileSys.ReadAllText(ipFile)
        e.ConnectionString = e.ConnectionString.Replace("119.119.120.120",ip)
    End If
End If

   其中的ip.txt中如何撰写？在ip.txt中直接写入119.119.120.120 就可以了吗？
