Dim hosts As New FileInfo("C:\Windows\system32\drivers\etc\hosts")
Console.WriteLine("ReadOnly?" + hosts.IsReadOnly)
Console.WriteLine("Size?" + hosts.Length) 
B Use the following code:
Dim hosts As New File("C:\Windows\system32\drivers\etc\hosts")
Console.WriteLine("ReadOnly?" + hosts.IsReadOnly)
Console.WriteLine("Size?" + hosts.Length) 
C Use the following code:
Dim hosts As New File("C:\Windows\system32\drivers\etc\hosts")
Console.WriteLine("ReadOnly?" + hosts.GetReadOnly)
Console.WriteLine("Size?" + hosts.GetLength) 
D Use the following code:
Dim hosts As New FileInfo("C:\Windows\system32\drivers\etc\hosts")
