Download file from a shared folder on network

Question

I am working on an asp.net application. I am showing user the list of files from a shared folder on network and I want user to be able to download any file from the list. But I am not able to locate that file in the code I get Invalid URI: The format of the URI could not be determined. error.

Code block -

var uri = new Uri(filePath); // Here I get the error
var fName = Path.GetFullPath(uri.LocalPath);
var fileInfo = new FileInfo(fName);

var response = HttpContext.Current.Response;

response.Clear();
response.ClearContent();
response.ClearHeaders();

response.Buffer = true;

response.AddHeader("Content-Description", "attachment;filename="+fileInfo.FullName);
response.WriteFile(fileInfo.FullName);
response.End();

Please suggest how can I get to that file and give it to the response header so that it could be downloaded.

Simply use

response.WriteFile(filePath);

There is no reason to use a URI.
