FileInfo Class

Use the FileInfo class for typical operations such as copying, moving, renaming, creating, opening, deleting, and appending to files

Many of the FileInfo methods return other I/O types when you create or open files. You can use these other types to further manipulate a file. For more information, see specific FileInfo members such as Open, OpenRead, OpenText, CreateText, or Create.

Sample Code

Class FileManagement
Private m_pFile As IO.FileInfo
Private m_sTempFile As String = "C:\Test.Txt"

Public Sub SampleCreateFile()
m_pFile = New IO.FileInfo(m_sTempFile)

' Check exist file name
If Not m_pFile.Exists Then
Dim objStream As IO.StreamWriter = m_pFile.CreateText()

objStream.WriteLine("Welcome to My Blog")
objStream.WriteLine("Thank you")

End If

End Sub

Public Sub SampleReadFile()
m_pFile = New IO.FileInfo(m_sTempFile)

If m_pFile.Exists Then
'Read Text
Dim objStream As IO.StreamReader = m_pFile.OpenText()

' Peek returns the next aviable charactor
While objStream.Peek() >= 0
End While

End If
End Sub

Public Sub SampleFileInfomation()

' Use class file to get file attributes

' Get Time

' Set Time a
IO.File.SetCreationTime(m_sTempFile, DateTime.Now)
IO.File.SetLastAccessTime(m_sTempFile, DateTime.Now)
IO.File.SetLastWriteTime(m_sTempFile, DateTime.Now)

End Sub

Public Sub SampleOther()
m_pFile = New IO.FileInfo(m_sTempFile)

' Copy File
m_pFile.CopyTo("C:\test2.txt", True)

' Move File

' Delete
m_pFile = New IO.FileInfo("C:\test2.txt")
End Sub
End Class

Now you could have your new website online and you’re keen to begin making some sales! But, how will you make gross sales in the event you do not need high volumes of visitors to your website?
