Q2: 求VB.NET写的自动保存txt文档的代码

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
