Open-XML saving word document produces corrupted file

Question

Although I'm new to the Open-XML world, I've already encountered some troubles/problems using it. The most of them were easily solved but I can't get around this one:

public class ReportDocument : IDisposable
{
    private MemoryStream stream;
    private WordprocessingDocument document;
    private MainDocumentPart mainPart;

    public byte[] DocumentData
    {
        get 
        {
            this.document.ChangeDocumentType(WordprocessingDocumentType.MacroEnabledDocument);
            byte[] documentData = this.stream.ToArray();
            return documentData;
        }
    }

    public ReportDocument()
    {
        byte[] template = DocumentTemplates.SingleReportTemplate;
        this.stream = new MemoryStream();
        stream.Write(template, 0, template.Length);
        this.document = WordprocessingDocument.Open(stream, true);
        this.mainPart = document.MainDocumentPart;
    }

    public void SetReport(Report report)
    {
        Body body = mainPart.Document.Body;
        var placeholder = body.Descendants<SdtBlock>();
        this.SetPlaceholderTextValue(placeholder, "Company", WebApplication.Service.Properties.Settings.Default.CompanyName);
        this.SetPlaceholderTextValue(placeholder, "Title", String.Format("Status Report for {0} to {1}", report.StartDate.ToShortDateString(),
            report.ReportingInterval.EndDate.ToShortDateString()));
        //this.SetPlaceholderTextValue(placeholder, "Subtitle", String.Format("for {0}", report.ReportingInterval.Project.Name));
        this.SetPlaceholderTextValue(placeholder, "Author", report.TeamMember.User.Username);
        this.SetPlaceholderTextValue(placeholder, "Date", String.Format("for {0}", DateTime.Today.ToShortDateString()));
    }

    private void SetPlaceholderTextValue(IEnumerable<SdtBlock> sdts, string alias, string value)
    {
        SdtContentBlock contentBlock = this.GetContentBlock(sdts, alias);
        Text text = contentBlock.Descendants<Text>().First();
        text.Text = value;
    }

    private SdtContentBlock GetContentBlock(IEnumerable<SdtBlock> sdts, string alias)
    {
        return sdts.First(sdt => sdt.Descendants<SdtAlias>().First().Val.Value == alias).SdtContentBlock;
    }

    public void Dispose()
    {
        this.document.Close();
    }
}

So i create a new document, based on a template it gains through the memory stream and want to write it back to a memory stream when the changes are made.

The big problem is, when i save the resulting byte array the data docx file is corrupted:

The document.xml in .\word is called document2.xml The document.xml.rels in .\word_rels is called document2.xml.rels and it contains I hope some of you can provide good solutions for it.

Try the project available on CodePlex @ worddocgenerator.codeplex.com. Your approach is already implemented there and samples are provided. — Atul Verma

Change your DocumentData property to this and I think it should work. The important thing is to close the document before you read the memorystream.

public byte[] DocumentData
    {
        get 
        {
            this.document.ChangeDocumentType(WordprocessingDocumentType.MacroEnabledDocument);
            this.document.MainDocumentPart.Document.Save();
            this.document.Close();            
            byte[] documentData = this.stream.ToArray();
            return documentData;
        }
    }
