}
else
{
//nothing in the URL as HTTP GET
Response.Write("Please provide a file to download.");
}
}
i'm guessing that your problem may lie in the value you are passing into your code.
you've not shown us the actual value of pathToOpen
private void openPdfFile(string pathToOpen)
Please very carefully check the value of pathToOpen
also, you can try an experiment by temporarily modifiy your method signature to use a real path:
private void openPdfFile(string " ... real path to some file ...")

You have to pass full path into respose check below code
// Your Code Response.AddHeader("Content-Disposition", "filename=" + file.Name); // Replace with below code Response.AddHeader("Content-Disposition", "filename=" + path);let me know if any query
