关于vb.net写txt文件的信息

vb.net 中对txt文件的读取、写入的方法！始终保持txt里面只有一行！

Public Class Form1

Private Sub 写入文件_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles 写入文件.Click

FileOpen(1, "D:\一行文件.txt", OpenMode.Output) ' Open file for output.

WriteLine(1, "想只保留文件为一行 那你就写一行好了") ' Print blank line to file.

FileClose(1) ' Close file.

End Sub

Private Sub 读取文件_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles 读取文件.Click

Dim TextLine As String

FileOpen(1, "D:\一行文件.txt", OpenMode.Input) ' Open file for output.

TextLine = LineInput(1) '读取一行就了

MsgBox(TextLine)

FileClose(1)

End Class

最简单的方法 还有很多方法 自己研究吧亲 希望能帮到你

vb.net创建一个txt文本,在debug文件夹里

设计一个窗口,添加一个名为textBox1的System.Windows.Forms.TextBox,

添加一个名为button1的System.Windows.Forms.Button.

为button1的单击事件添加如下处理函数：

Sub Button1Click(sender As Object, e As EventArgs)

'f是你的文本文件的文件名

Const f As String="t.txt"

Dim sw As System.IO.StreamWriter=Nothing

Try

If Not System.IO.File.Exists(f) Then

sw=System.IO.File.CreateText(f)

Else

sw=New System.IO.StreamWriter(f,True)

End If

sw.WriteLine(textBox1.Text)

Finally

If sw IsNot Nothing Then

sw.close()

End Try

vb.net如何批量生成一堆TXT文件?

function writetxt (filename as string,currenttxt as string) filename ="c:\" filename ".txt" 'filename要生成的文件名 currenttxt当前写入的文件内容. open filename for output As #1 print #1, currenttxt close #1 end functiong sub xxx ... '定义rs为recorder,并生成记录集, ... rs.movefirst while not rs.eof call writetxt rs.filds("文章标题").value ,rs.filds("文章").value rs.movenext loop '关闭记录集等 end sub

在vb.net中如何生成一个txt文件,并且写入一个数组的值?

已测试,代码如下：

Imports?System.IO?'引入文本操作

Public?Class?Form1

Private?Sub?Button1_Click(ByVal?sender?As?System.Object,?ByVal?e?As?System.EventArgs)?Handles?Button1.Click

Dim?txt?As?String?=?Me.getTxt

SaveTxt(txt)

End?Sub

'取得存储的文本

Private?Function?getTxt()?As?String

Dim?x(0?To?10)?As?Integer

For?i?As?Integer?=?0?To?x.Length?-?1

x(i)?=?CInt(100?*?Rnd())

Next

Dim?str?As?String?=?""

For?j?As?Integer?=?0?To?x.Length?-?1

str?◆=?x(j).ToString?vbCrLf

Return?str

End?Function

'存储文本

Private?Sub?SaveTxt(ByVal?v?As?String)

Dim?fp?As?String?=?GetSavePath()

If?String.IsNullOrEmpty(fp)?=?False?Then

'StreamWriter

Dim?Swriter?As?New?StreamWriter(fp,?False)?'覆盖或新建

Swriter.WriteLine(v)

Swriter.Close()

End?If

'取得存储路径

Private?WithEvents?sd?As?New?SaveFileDialog

Private?Function?GetSavePath()?As?String

sd.FileName?=?""

sd.AddExtension?=?True

sd.DefaultExt?=?"txt"

sd.Filter?=?"TXT文件(*.txt)|*.txt"

sd.ShowDialog()

Return?sd.FileName

End?Class

测试截图如下.

如何用vb.net编写读取txt内容的代码?

代码如下：

'写文本文件

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

'创建(写入)一个文本文件

Dim MyStream As New System.IO.FileStream(Application.StartupPath "\Ssk.txt", System.IO.FileMode.Create)

Dim MyWriter As New System.IO.StreamWriter(MyStream, System.Text.Encoding.Default)

MyWriter.WriteLine(TextBox1.Text)

MyWriter.Flush()

MyWriter.Close()

MyStream.Close()

'读文本文件

'读取一个文本文件

MyReader.Close()
