Process.Start doenst work now application is live? C# asp.net - Opening folder

Hi, I have an upload function which saves attchments to a folder. I am trying to access the uploaded attachments using Process.Start to open them.

This worked fine when local but now its on the web server it no longer works. Im presuming it becuase of Process.Start. My issues is that I get the error that it cant locate the folder/file but im sure its mapped properly.

Any ideas why its doing this or how to overcome it?

Thanks

}

string Location = "~\\Attachments\\";
        
string File = lblLink.Text;
     
Process.Start(Location + File);
        
	   //"file:///W:/Attachments"
            //lblLink.Text = Location + File;
            //Debug.Write (Location + File);
            //Console.WriteLine(Location + File);
            //Console.ReadLine();
        }

Just type the location in the URL bar and I got a HTTP 403 error

Have you tried Process.Start(Server.MapPath("~/Attachments/" + fileName)) ?

Hi,

Process.Start will not open file in client machine.

Try below code:

string path = "File Name with Path Here";
System.IO.FileInfo file = new System.IO.FileInfo(path);

if (file.Exists)
{
   Response.Clear();
   Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
   Response.AddHeader("Content-Length", file.Length.ToString());
   Response.ContentType = "application/octet-stream";
   Response.WriteFile(file.FullName);
   Response.End();
}

@ lazyberezovsky: - Yeah I have, no luck with that either.

@rajapandian_81: The file name changes so I cant write the name of it. Can this be done stating the path and a string the contains the file name?

Tired this below but no luck

string path = @"\Attachments\ + File";
        System.IO.FileInfo file = new System.IO.FileInfo(path); 

if (file.Exists) 
{ 
   Response.Clear(); 
   Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name); 
   Response.AddHeader("Content-Length", file.Length.ToString()); 
   Response.ContentType = "application/octet-stream"; 
   Response.WriteFile(file.FullName); 
   Response.End(); 
}

----> string path = @"\Attachments\ + File";

Please clarify
What is Attachments. Is it virtual directory?

I hope File is string variable.
Try
string path = @"Attachments\" + File;

the url address is something like this. It does open the file(s)

http://itsuit.it.ac.uk/web/Attachments/634021777431309205Mine.doc

string path = @"\Attachments\ + File";
Do not gives you concatenation. You placed quotes in wrong place.
