本文实例讲述了VB实现按行读取文本文件的方法。分享给大家供大家参考。具体如下：

'(general declaration) Dim nFileNum As Integer, sText As String, sNextLine As String, lLineCount As Long '================================== Private Sub Command1_Click() ' Get a free file number nFileNum = FreeFile ' Open a text file for input. inputbox returns the path to read the file Open "C:Documents and SettingsSudeepMy Documents3.txt" For Input As nFileNum lLineCount = 1 ' Read the contents of the file Do While Not EOF(nFileNum) Line Input #nFileNum, sNextLine 'do something with it 'add line numbers to it, in this case! sNextLine = sNextLine & vbCrLf sText = sText & sNextLine Loop Text1.Text = sText ' Close the file Close nFileNum End Sub

希望本文所述对大家的VB程序设计有所帮助。
