System.IO.DirectoryNotFoundException: Could not find a part of the path

Question

_{Wednesday, February 15, 2012 2:59 AM}

I have been getting this message.  sometimes the code just works fine, sometimes the error occurs.

Could not find a part of the path 'C:\User\Documents\ Sites\MySite\page\form.pdf'.

here is the code that creates the file and the error line

@using System.IO;
.....
@{
.....
try{
var output = new FileStream(Server.MapPath("form.pdf"),FileMode.Create);
            var writer = PdfWriter.GetInstance(doc, output);

......
catch (DocumentException dex)
            {
                throw (dex);
            }
            catch (IOException ioex)
            {
                throw (ioex); (the error is on this line)
            }
            finally
            {
                doc.Close();
            }

You would need to ensure that the directory is created prior to creating the file.

    var appDataPath = Server.MapPath("~/App_Data/");
    if (!Directory.Exists(appDataPath)) {
        Directory.Create(appDataPath);
    }
    var filePath = Path.Combine(appDataPath, Path.GetRandomFileName() + ".pdf");
    using (var output = File.Create(filePath)) {
       // Do stuff here

    }

That should be CreateDirectory:

 if (!Directory.Exists(appDataPath)) {
     Directory.CreateDirectory(appDataPath);
 }

Can you put the stack trace to know if the exception was thrown in the "new FileStream..." line or in the next one?

You don't have to check, Directory.CreateDirectory() never throws an exception if the directory already exists.
