Receiving IOException

Question

I'm getting the IOException Error when I try this, and I'm not sure what I'm doing wrong:

This is my code:

FileStream fStream = new FileStream(PDFFilePath(), FileMode.CreateNew, FileAccess.ReadWrite);

Where

private string PDFFilePath()
    {
        m_sFilePath = "C:/Pictures/";
        return m_sFilePath;
    }

What am I missing?

I'm using this FileStream to save PDF documents using the Pdf.Select NuGet. It uses a method:

PdfDocument.Save(Stream stream);

I think you should be specifying your path this way:

private string PDFFilePath(string filename)
{
    m_sFilePath = @"C:\Pictures\" + filename;
    return m_sFilePath;
}

Like @Reisclef said, you have to provide a file path, not a directory. Since you're using FileMode.CreateNew, it has to be a new file, so you might also want to use File.Exists(m_sFilePath) before returning.
