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
Next
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
End Sub
'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 Function
End Class
测试截图如下。
【vb.net】怎么把text里面的内容生成一个txt文件
Dim SaveFileDialog1 As New SaveFileDialog()
'创建一个保存对话框
SaveFileDialog1.Filter = "txt files (*.txt)|*.txt"
'设置
扩展名
If SaveFileDialog1.ShowDialog() = System.Windows.Forms.DialogResult.OK Then
'如果确定保存
My.Computer.
FileSystem
.WriteAllText(SaveFileDialog1.Filename, Textbox1.Text,False)
'保存文本,False表示不追加文本,直接覆盖其内容
End If
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 If
End Try
End Sub
