在 vb 2005 中逐行浏览文本文件

发布于 2024-07-08 13:59:13 字数 190 浏览 9 评论 0原文

因此，我的程序本质上需要逐行遍历纯文本文件：

Read line 1:
Do commands
loop
Read line2:
Do Commands
loop

等等，直到完成整个文件，有人知道这方面有什么好的编码示例吗？所有教程似乎都显示了打开和写入/读取文本文件，但没有介绍如何操作逐行进行。

So my program needs to go through a plain text file line by line essentially:

Read line 1:
Do commands
loop
Read line2:
Do Commands
loop

etc until its done with the entire file does anyone know any good coding examples for this, all the tutorials seem to show open and writing/reading textfiles but nothing on how to do it line by line.

For Each line As String In System.IO.File.ReadAllLines("file.txt")
  ' Do Something'
Next

For Each line As String In System.IO.File.ReadAllLines("file.txt")

你可以这样做：

Using f As System.IO.FileStream = System.IO.File.OpenRead("somefile.txt")
    Using s As System.IO.StreamReader = New System.IO.StreamReader(f)
        While Not s.EndOfStream
            Dim line As String = s.ReadLine

            'put you line processing code here

        End While
    End Using
End Using

You could do it like this:

Using f As System.IO.FileStream = System.IO.File.OpenRead("somefile.txt")
    Using s As System.IO.StreamReader = New System.IO.StreamReader(f)
        While Not s.EndOfStream
            Dim line As String = s.ReadLine

            'put you line processing code here

        End While
    End Using
End Using
