How to check whether a filie is existing

[szms]

Well I am tying to open a file for reading which does not exist and thus getting an erro message. How to check whether a file is existing before I open it for reading?

I am using VB.NET and doing windows application

Well what I would probably do is create a data set with all the files in the directory in it, then check the file name string with the data set. There is probably a more efficient way, but this could make it easier for you if you want to use other information about the file or several files. I can probably post code on how to populate a data set with file info or read from a directory.

You should use the System.IO.File class. It has a shared method called Exists.

Imports System.IO

' then in the function

If File.Exists(filepath) Then
  'open it
Else
  'dont open it.
End If

HTH.
