DocIO saves file but cannot reopen it

I am creating and saving a  Word file using the following c#:

            WordDocument document = new WordDocument();

            //Adds a new section into the Word document

            IWSection section = document.AddSection();

            //Specifies the page margins

            section.PageSetup.Margins.All = 50f;

            //Adds a new simple paragraph into the section

            IWParagraph Paragraph1 = section.AddParagraph();

            ////Sets the paragraph's horizontal alignment as center

            Paragraph1.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Center;

            //Adds a text range into the paragraph

            IWTextRange TextRange1 = Paragraph1.AppendText(title);

            //sets the font formatting of the text range

            TextRange1.CharacterFormat.Bold = true;

            TextRange1.CharacterFormat.FontName = "Georgia";

            TextRange1.CharacterFormat.FontSize = 20;

            //Adds another text range into the paragraph

            IWParagraph Paragraph2 = section.AddParagraph();

            ////Sets the paragraph's horizontal alignment as center

            Paragraph2.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Left;

            IWTextRange TextRange2 = Paragraph2.AppendText("Introduction");

            TextRange2.CharacterFormat.Bold = true;

            TextRange2.CharacterFormat.FontName = "Georgia";

            TextRange2.CharacterFormat.FontSize = 14;

            //Adds another text range into the paragraph

            IWTextRange TextRange3 = Paragraph2.AppendText(newintro);

            TextRange3.CharacterFormat.FontName = "Georgia";

            TextRange3.CharacterFormat.FontSize = 12;

            IWTextRange TextRange4 = Paragraph2.AppendText("Ingredients");

            TextRange4.CharacterFormat.Bold = true;

            TextRange4.CharacterFormat.FontName = "Georgia";

            TextRange4.CharacterFormat.FontSize = 14;

            //Adds another text range into the paragraph

            IWTextRange TextRange5 = Paragraph2.AppendText(newingr);

            TextRange5.CharacterFormat.FontName = "Georgia";

            TextRange5.CharacterFormat.FontSize = 12;

            TextRange5.CharacterFormat.Italic = true;

            IWTextRange TextRange6 = Paragraph2.AppendText("Instructions");

            TextRange6.CharacterFormat.Bold = true;

            TextRange6.CharacterFormat.FontName = "Georgia";

            TextRange6.CharacterFormat.FontSize = 14;

            //Adds another text range into the paragraph

            IWTextRange TextRange7 = Paragraph2.AppendText(newsteps);

            TextRange7.CharacterFormat.FontName = "Georgia";

            TextRange7.CharacterFormat.FontSize = 12;

            TextRange7.CharacterFormat.Italic = true;

            try

            {

                PermissionStatus status = await CheckAndRequestWritePermission();

                Stream stream = new FileStream(path, FileMode.OpenOrCreate);

                document.Save(stream, FormatType.Docx);

                document.Close();

            }

The Word file is created and saved without errors, but when I try to open it I get an error message:

Syncfusion.Compression.Zip.ZipException: 'Zip exception.Can't locate end of central directory record. Possible wrong file format or archive is corrupt.'

The c# to open the file is:

            Stream stream = new FileStream(path, FileMode.OpenOrCreate);

            WordDocument document = new WordDocument();

            document.Open(stream, FormatType.Docx);


The path variabe is set for bot saving and opening to:

/storage/emulated/0/Documents/Fave con pecorino-Broad beans with pecorino.docx

Could you please investigate

Hi Paul,

We have tried to reproduce the reported issue using the given details at our end.

From the given code snippet, we found that you haven’t closed the stream after saving the Word document which leads to document corruption. So, when reopening the saved corrupted Word document, the reported ZipException occurs.

In order to make this work, we suggest you close the stream after saving the Word document and then reopen the saved Word document. Please refer the below highlighted code snippet to resolve the reported issue.

//Adds another text range into the paragraph

IWTextRange TextRange7 = Paragraph2.AppendText(newsteps);

TextRange7.CharacterFormat.FontName = "Georgia";

TextRange7.CharacterFormat.FontSize = 12;

TextRange7.CharacterFormat.Italic = true;

try

{

PermissionStatus status = await CheckAndRequestWritePermission();

Stream stream = new FileStream(path, FileMode.OpenOrCreate);

document.Save(stream, FormatType.Docx);

document.Close();

stream.Close();

}

Regards,
Akash A.
