1、System.IO.File.Create(Application.StartupPath + "e.txt")
2、写文件
Dim sw As StreamWriter = New StreamWriter(Application.StartupPath + "e.txt")
sw.Write("This is the ")
sw.WriteLine("header for the file.")
sw.WriteLine("-------------------")
sw.Write("The date is: ")
sw.WriteLine(DateTime.Now)
sw.Close()
3、读文件
Dim sr As StreamReader = New StreamReader(Application.StartupPath + "e.txt")
Dim line As String
Do
line = sr.ReadLine()
Console.WriteLine(Line)
Loop Until line Is Nothing
sr.Close()
Catch E As Exception
' Let the user know what went wrong.
Console.WriteLine("The file could not be read:")
Console.WriteLine(E.Message)
End Try

在MSDN里面输入个File 或者 FileInfo 就能解决Top
