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 numbernFileNum = FreeFile' Open a text file for input. inputbox returns the path to read the fileOpen "C:\Documents and Settings\Sudeep\My Documents\3.txt" For Input As nFileNumlLineCount = 1' Read the contents of the fileDo 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 & sNextLineLoopText1.Text = sText' Close the fileClose nFileNumEnd Sub

希望本文所述对大家的VB程序设计有所帮助。
