Public Class Test
Public Shared Sub Main()
Dim path As String = "c:\temp\MyTest.txt"
If File.Exists(path) = False Then
' Create a file to write to.
Dim sw As StreamWriter = File.CreateText(path)
sw.WriteLine("Hello")
sw.WriteLine("And")
sw.WriteLine("Welcome")
sw.Flush()
sw.Close()
End If

' Open the file to read from.
Dim sr As StreamReader = File.OpenText(path)
Do While sr.Peek() >= 0
Console.WriteLine(sr.ReadLine())
Loop
sr.Close()
End Sub
End Class
看看这个例子就知道了
