By default, full read/write access to new files is granted to all users.
This method is a wrapper for the functionality provided by File..::.Create.

The following example creates a reference to a file, and then creates the file on disk using FileInfo.Create().

End If
'Create the file.
Dim fs As FileStream = fi.Create()
Dim info As Byte() = New UTF8Encoding(True).GetBytes("This is some text in the file.")
'Add some information to the file.
fs.Write(info, 0, info.Length)
fs.Close()
'Open the stream and read it back.
Dim sr As StreamReader = fi.OpenText()
Do While sr.Peek() >= 0
Console.WriteLine(sr.ReadLine())
Loop
sr.Close()
End Sub
