代码如下
100%正确，刚刚写的，调试好了
Imports System.io
Public Class form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim fs As New FileStream("d:\文本.txt", FileMode.Create, FileAccess.Write)
Dim r As New StreamWriter(fs)
Dim I As Integer
r.Write(TextBox1.Lines(I))
r.Flush()
r.Close()
End Sub
End Class
路径自己修改
（你的给分是我回答的动力）
Dim i As Integer
Dim j As Integer
Dim myFile As New System.IO.StreamWriter("c:\Test.txt")
Dim strTemp As String = ""
For j = 0 To frmQuery.DataGridView1.RowCount - 1
strTemp = ""
For i = 0 To frmQuery.DataGridView1.Columns.Count - 1
strTemp = "'" frmQuery.DataGridView1(i, j).Value "'" ","
Next
myFile.WriteLine(strTemp)
Next
myFile.Close()
格式为表格每行保存为文本文件的一行，字段之间以逗号分隔。
直接给你保存和读取TXT的VB.NET的函数代码，你只要在触发事件中调用就可以了，注意换行，有的是显示不下去才显示两行的，还有strFilePath代表文件路径，TempENG代表文件编码格式如：UTF-8或者GB2312，strText 代表内容字符串。
#Region "读取TXT"
Public Function ReadTxt(ByVal strFilePath As String, ByVal TempENG As String) As String
Dim mySr As System.IO.StreamReader
Dim strS As String
Dim n%
strS = ""
mySr = New System.IO.StreamReader(strFilePath, System.Text.Encoding.GetEncoding(TempENG))
Do
Dim line$ = mySr.ReadLine()
strS = strS line vbCrLf
n = n + 1
Loop Until mySr.EndOfStream = True
mySr.Close()
Return strS
End Function
#End Region
#Region "保存TXT"
Public Function SaveTxt(ByVal strFilePath As String, ByVal strText As String, ByVal TempENG As String) As Boolean
Try
If Dir(strFilePath) "" Then File.Delete(strFilePath)
Dim mySw As System.IO.StreamWriter
Dim strLine() As String
mySw = New System.IO.StreamWriter(strFilePath, True, System.Text.Encoding.GetEncoding(TempENG))
strLine = Split(strText, vbCrLf)
For i As Integer = 0 To UBound(strLine)
mySw.WriteLine(strLine(i))
Next
mySw.Close()
Return True
Catch ex As Exception
Return False
End Try
End Function
#End Region
