How to properly serve a PDF file

Question

I am using .NET 3.5 ASP.NET. Currently my web site serves a PDF file in the following manner:

context.Response.WriteFile(@\"c:\\blah\\blah.pdf\");

Answer 1

Building upon Peter Lillevold's answer, I went and just made some extension methods for his above functions.

public static void WriteTo(this Stream inputStream, Stream outputStream)
{
    const int bufferSize = 64 * 1024;
    var buffer = new byte[bufferSize];

    while (true)
    {
        var bytesRead = inputStream.Read(buffer, 0, bufferSize);
        if (bytesRead > 0)
        {
            outputStream.Write(buffer, 0, bytesRead);
        }
        if ((bytesRead == 0) || (bytesRead < bufferSize)) break;
    }
}

public static void WriteToFromFile(this Stream outputStream, string inputFile)
{
    using (var inputStream = new FileStream(inputFile, FileMode.Open, FileAccess.Read))
    {
        inputStream.WriteTo(outputStream);
        inputStream.Close();
    }
}
