Hi I have an asp.net web application. I am trying to access files from remote server (on local network) and unfortunately it isn’t working out. Problem is I am not sure if the error is cos the path mentioned isn’t correct or is this a problem with iis7 permissions. I have set <identity impersonate="true"... in web.config file. Below is the code i am trying to access :

C#

Response.AppendHeader("content-disposition", "attachment; filename=" + 
 document.FileName);
 Response.ContentType = document.ContentType;
 String filepath = "\\<server-name>\<shared folder>\file.txt";
 Response.WriteFile(filepath);
 Response.End();

I have tried every possible combination of filepath string. Nothing works. Please help.

have you tried accessing the file from windows explorer with a user with the right credentials? Also, the one mistake I see is you're missing the "@" preceding the string, otherwise, you need to qualify your escapes "\" with more escapes.

Hi I tried that :

String filepath = @"\\<server-name>\\<shared folder>\\test.txt";

I get the exception:

"Could not find file

'\\\\<server-name>\\<shared folder>\\test.txt'

UPDATE SM: When you put @, you don't use escape sequences! Read books please!
try:

String filepath = @"\\<server-name>\<shared folder>\test.txt";

AFAIK you can't access a file from network like that. Please read the following article for details.
