我是靠谱客的博主瘦瘦芝麻，最近开发中收集的这篇文章主要介绍VB实现按行读取文本文件的方法，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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。
