请教:VB.NET中文件写入问题!!

本人刚接触.NET 遇到这样一个问题: 要把一段文字(STRING)写入到指定文件中,不知道用何方法,请熟悉这方面的朋友指点一下.具体判断是 如果在指定路径下 没有该文件名,则在该路径下创建文件. 并将上面文字写入文件中 保存.

请高手帮忙 不胜感激!!

Imports System.IO

Imports System.Text

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim s As String

Dim bte As Byte()

Dim myfile As New FileStream( d:/123.txt , FileMode.Create, FileAccess.Write)

s = 要保存到文件的文字

bte = Encoding.Default.GetBytes(s)

myfile.Write(bte, 0, bte.Length)

myfile.Close()

End Sub

End Class

__________________________________________________________________________

Dim chl As New System.IO.StreamWriter( 路径，比如c:/123.txt , True)

chl.WriteLine( 要写入的字符串 )

chl.Close()

__________________________________________________________________________

Dim chl As New System.IO.StreamWriter( 路径，比如c:/123.txt , True)

chl.WriteLine( 要写入的字符串 )

chl.Close()

__________________________________________________________________________

没看到还要创建文件，补充

If Not File.Exists( 路径，比如c:/123 ) Then

File.Create( 路径，比如c:/123 ).Close()

End If

Dim chl As New System.IO.StreamWriter( 路径，比如c:/123.txt , True)

chl.WriteLine( 要写入的字符串 )

chl.Close()

__________________________________________________________________________

FileOpen(1, c:/new.txt , OpenMode.Append)

PrintLine(1, 寫入第一行 )

Print(1, 寫入第二行 )

Print(1, 接在第二行後寫入 寫入第三行 )

FileClose(1)

也可以用MY命名空间

__________________________________________________________________________

my.computer.filsystem.writealltext(路径，要写入的文件内容，是覆盖还是追加)
