small c# program to interact with php script on website

hi

 

i m from php web background. 

 

i wanted to access a computer hard drive file with php script on my website

 

php is not capable alone to interact with desktop computer files.

 

and i dont want to upload these desktop files to my web server.

 

so i need a small program in c# to interact with php script on my website

 

a small program that will install on my computer

 

on click it will open a dialog box with input field and browse button

 

in the input field i will enter the file name and location of my C: \ or D:\ Drive on hard disk

 

and my php script on website should able to read that file

 

i know how to read ms-access and excel files with php

 

but dont know how to make php website interact with desktop 

 

so is there any small open source c# program available to download and which can do the above task of interaction with php script on my website ??
