Imports System.IO
Imports System.Text
Class FStream
Shared Sub Main()
Const fileName As String = "Test#@@#.dat"
' Create random data to write to the file.
Dim dataArray(100000) As Byte
Dim randomGenerator As New Random()
randomGenerator.NextBytes(dataArray)
Dim fileStream As FileStream = _
new FileStream(fileName, FileMode.Create)
Try
' Write the data to the file, byte by byte.
For i As Integer = 0 To dataArray.Length - 1
fileStream.WriteByte(dataArray(i))
Next i
' Set the stream position to the beginning of the stream.
fileStream.Seek(0, SeekOrigin.Begin)
' Read and verify the data.
For i As Integer = 0 To _
CType(fileStream.Length, Integer) - 1
If dataArray(i) <> fileStream.ReadByte() Then
Console.WriteLine("Error writing data.")
Return
End If
Next i
Console.WriteLine("The data was written to {0} " & _
"and verified.", fileStream.Name)
Finally
fileStream.Close()
End Try
End Sub
End Class示例2: FSSeek
' 導入命名空間
Imports System.IO
Public Class FSSeek
Public Shared Sub Main()
Dim offset As Long
Dim nextByte As Integer
' alphabet.txt contains "abcdefghijklmnopqrstuvwxyz"
Using fs As New FileStream("c:\temp\alphabet.txt", FileMode.Open, FileAccess.Read)
