Question

I have following piece of code:

        byte[] snapthotBytes, snapthotBytes2;
        string stringOutput, stringOutput2;
        IInvestigationDump investigationDump = new HtmlSnapshotDump();
        using (TextWriter writer = new StringWriter())
        {
            investigationDump.Dump(investigation, writer);
            snapthotBytes = Encoding.UTF8.GetBytes(writer.ToString());
            stringOutput = writer.ToString();
        } // end of first implementation

        using (MemoryStream stream = new MemoryStream())
        using (TextWriter writer = new StreamWriter(stream))
        {
            investigationDump.Dump(investigation, writer);
            stream.Seek(0, SeekOrigin.Begin);
            var reader = new StreamReader(stream);
            stringOutput2 = reader.ReadToEnd();
            snapthotBytes2 = stream.ToArray();
        } // end of second implementation

        // stringOutput != stringOutput2 - content wise
        // snapthotBytes != snapthotBytes2 - content wise

Some introduction:

• Dump method just traverses investigation object and renders an HTML report (by writing to a writer object).
• Appart from the fact that StringWriter uses UTF-16 encoding and XML declaration will differ, both stringOutput & stringOutput2 should have the same content. Dump methods signature is:

void Dump(IInvestigation investigation, TextWriter writer);

• Dump method just writes to a writer, without any conditions etc.

At first I used MemoryStream code snippet, it was easier as I received byte[] straightaway. But soon I realized a bug. Amazingly it turned out that stringOutput2 (produced by MemoryStream solution) is trimmed, it is shorter! It just ends with trimmed HTML content:

        <tr>
          <td>Certificate or License No</td>
          <td class="value">Friuan</td>
          <td>Place of Issue</td>
          <td class="value">Foruan</td>
        </tr>
        <tr>
          <td>Award Date</td>
          <td 

Answer 1

How about

writer.Flush()

before trying to read the stream?
