File.Exist Question

Hello everyone. I have just started learing visual basic .net on my
own and I have a very newbie question. I have the following code in my
program:

Dim path As String = "c: empMyTest.txt"
If File.Exists(path) Then
MessageBox.Show("This file Exists")
End If

I cannot build the project and I get the folloing error in the task
list.

Name `File` is not declared.

Can someone explain what I have wrong with this?

Thanks in advance,

Kypper

Try this. Before your private sub starts include
Import System.IO.File

File.Exist Question

Hi,

make sure you have added Imports System.IO
at the begining of the code ...

Also please note that if you do not have sufficient permissions it
will still through false ... check file permissions please

Or instantiate a instance of the class as:
Dim fMyFile As System.IO.File

You think in .net you can use those names cause they are there when you type
them. Yet, the are all in the system.dll file but you must pull them from
the parent class that they belong in. For example the file class is a part
of system.io. You cannot call it from system immediately. However, it is
shown in system cause it`s a part of system. It may sound confusing but very
easy when you get comfortable with it.
