Write Text file with tab-delimited in Asp.Net Core 2.2

Hi do you have any guides, work aid or step by step how to export to text with tab delimited. Im using Asp.Net Core 2.2 MVC EF. I want to export a list from my table.. I want to have a button where the user click in this DownloadFile Action will trigger.
public IActionResult DownloadFile()
{
var payments = new List<BdoPE>
{
new BdoPE
{
DocDateInDoc = "01/01/2019",
DocType = "DZ",
CompanyCode = "3000",
PosDateInDoc = "01/01/2019",
FiscalPeriod = "01",
CurrentKey = "PHP",
RefDocNum = "Over-The-Counter",
DocHeadT = "BDO",
PosKeyInNextLine = "40",
AccMatNextLine = "11231131",
AmountDocCur = "0000000010050",
ValDate = "01/01/2019",
AssignNum = "EEA",
ItemText = "1000136212 ",
PosKeyInNextLine2 = "15",
AccMatNextLine2 = "0115027FF",
AmountDocCur2 = "0000000010050",
BaseDateDueCal = "01/01/2019",
ItemText2 = "1000136212"
},
};
// I want this part to let the user select where they want to save the text file.
using (var writer = new StreamWriter("path\\to\\file.txt")) // not static location like this one.
using (var csv = new CsvWriter(writer))
{
csv.WriteHeader<BdoPE>();
csv.WriteRecord(payments);
}
// where should i put the delimiter part?
return;
}

You will need to setup the CsvWriter with a Configuration.
Thus, your code needs only a slight change:
[...]
var configuration = new CsvHelper.Configuration.Configuration();
configuration.Delimiter = '\t';
using (var csv = new CsvWriter(writer, configuration))
{
csv.WriteHeader<BdoPE>();
csv.WriteRecord(payments);
}
[...]

I use the code below to set the Delimiter using CsvHelper.
var config = new CsvConfiguration(CultureInfo.CurrentCulture)
{
Delimiter = "\t"
};

How can i create a word header from a html string

I'm generating a word docx file from a html string and using various articles I've found how to add simple headers and footers to that document.
What I now need to do is generate the header from a html string too but I'm struggling to find an example of how this is done.
The author of this question:
Export docx/doc First Header and Footer as docx File Using openXML
says he has done it but unfortunately he hasn't posted an example.
My code below successfully adds a header but as you can see from the code it will only add the html as text in the header, whereas I want to pass in a html string and that to appear in the header as formatted html.
Has anyone done this?
static void AddHeaderPart(MainDocumentPart mainPart, string headerHtml, Encoding encoding)
{
if (mainPart == null || string.IsNullOrEmpty(headerHtml))
{return;}
// Create a new header part.
HeaderPart headerPart = mainPart.AddNewPart<HeaderPart>();
// Get Id of the headerPart.
string rId = mainPart.GetIdOfPart(headerPart);
// Call GenerateHeaderPartContent
GenerateHeaderPartContent(mainPart, headerPart, headerHtml, encoding);
// Get SectionProperties and Replace HeaderReference with new Id.
IEnumerable<SectionProperties> sectPrs = mainPart.Document.Body.Elements<SectionProperties>();
foreach (var sectPr in sectPrs)
{
// Delete existing references to headers.
sectPr.RemoveAllChildren<HeaderReference>();
// Create the new header reference node.
sectPr.PrependChild<HeaderReference>(new HeaderReference() { Id = rId, Type = HeaderFooterValues.Default });
}
}
static void GenerateHeaderPartContent(MainDocumentPart mainPart, HeaderPart headerPart, string headerHtml, Encoding encoding)
{
Header header1 = new Header() { MCAttributes = new MarkupCompatibilityAttributes() { Ignorable = "w14 wp14" } };
header1.AddNamespaceDeclaration("wpc", "http://schemas.microsoft.com/office/word/2010/wordprocessingCanvas");
header1.AddNamespaceDeclaration("mc", "http://schemas.openxmlformats.org/markup-compatibility/2006");
header1.AddNamespaceDeclaration("o", "urn:schemas-microsoft-com:office:office");
header1.AddNamespaceDeclaration("r", "http://schemas.openxmlformats.org/officeDocument/2006/relationships");
header1.AddNamespaceDeclaration("m", "http://schemas.openxmlformats.org/officeDocument/2006/math");
header1.AddNamespaceDeclaration("v", "urn:schemas-microsoft-com:vml");
header1.AddNamespaceDeclaration("wp14", "http://schemas.microsoft.com/office/word/2010/wordprocessingDrawing");
header1.AddNamespaceDeclaration("wp", "http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing");
header1.AddNamespaceDeclaration("w10", "urn:schemas-microsoft-com:office:word");
header1.AddNamespaceDeclaration("w", "http://schemas.openxmlformats.org/wordprocessingml/2006/main");
header1.AddNamespaceDeclaration("w14", "http://schemas.microsoft.com/office/word/2010/wordml");
header1.AddNamespaceDeclaration("wpg", "http://schemas.microsoft.com/office/word/2010/wordprocessingGroup");
header1.AddNamespaceDeclaration("wpi", "http://schemas.microsoft.com/office/word/2010/wordprocessingInk");
header1.AddNamespaceDeclaration("wne", "http://schemas.microsoft.com/office/word/2006/wordml");

Paragraph paragraph1 = new Paragraph();
ParagraphProperties paragraphProperties1 = new ParagraphProperties();
ParagraphStyleId paragraphStyleId1 = new ParagraphStyleId() { Val = "Header" };
paragraphProperties1.Append(paragraphStyleId1);
//This adds the headerHtml as text - how to add it as html?
Run run1 = new Run();
Text text1 = new Text();
text1.Text = headerHtml;
run1.Append(text1);
paragraph1.Append(paragraphProperties1);
paragraph1.Append(run1);
header1.Append(paragraph1);
headerPart.Header = header1;
}

So the code below uses an altChunk to add html into the header. It's not perfect as I get validation errors when I use the OpenXmlValidator to validate the generated document although the doc still opens ok in word but I'm posting it here as an answer as it does do what I asked above & it might help others:

{
Header header1 = new Header() { MCAttributes = new MarkupCompatibilityAttributes() { Ignorable = "w14 wp14" } };

How to dynamically add a page number in footer in Microsoft OXML c#

I'm creating a word document using OXML in Visual Studio. I don't know how long it is going to be and I need to add a simple page number in the footer of the document.
To generate headers and footers I used this:
https://msdn.microsoft.com/en-us/library/ee355228(v=office.12).aspx
As I understand, this presets the default headers/footers before I even write anything in the document. So I'm not quite sure if I can add page numbering to this? I'd really appreciate the help, because I've been stuck on this for a whole day...

You can add dynamic page numbers by adding a SimpleField with an Instruction of "PAGE". Word will automatically update any such field with the correct page number.
In order to code that you can adapt the GeneratePageFooterPart in the link you provided to include a SimpleField in the Run that gets added to the Footer:
private static Footer GeneratePageFooterPart(string FooterText)
{
var element =
new Footer(
new Paragraph(
new ParagraphProperties(
new ParagraphStyleId() { Val = "Footer" }),
new Run(
new Text(FooterText),
// *** Adaptation: This will output the page number dynamically ***
new SimpleField() { Instruction = "PAGE" })
));
return element;
}
Note that you can change the format of the page number by postfixing the PAGE text. From the Ecma Office Open XML Part 1 - Fundamentals And Markup Language Reference.pdf:
When the current page number is 19 and the following fields are updated:
PAGE
PAGE \* ArabicDash
PAGE \* ALPHABETIC
PAGE \* roman
the results are:
19
- 19 -
S
xix
So to get roman numerals for example you would need to change the SimpleField line of code above to:
new SimpleField() { Instruction = "PAGE \\* roman" })
or (if you prefer)
new SimpleField() { Instruction = #"PAGE \* roman" })

Try this:
private static void GenerateFooterPartContent(WordprocessingDocument package, string text = null)
{
FooterPart footerPart1 = package.MainDocumentPart.FooterParts.FirstOrDefault();
if (footerPart1 == null)
{
footerPart1 = package.MainDocumentPart.AddNewPart<FooterPart>();
}
var relationshipId = package.MainDocumentPart.GetIdOfPart(footerPart1);
// Get SectionProperties and set HeaderReference and FooterRefernce with new Id
SectionProperties sectionProperties1 = new SectionProperties();
FooterReference footerReference2 = new FooterReference() { Type = HeaderFooterValues.Default, Id = relationshipId };
sectionProperties1.Append(footerReference2);
package.MainDocumentPart.Document.Body.Append(sectionProperties1);
Footer footer1 = new Footer();
Paragraph paragraph2 = CreateParagraph(package, string.Empty, "Footer");
Run r = new Run(new SimpleField() { Instruction = "DATE" });
paragraph2.Append(r);
if (!string.IsNullOrWhiteSpace(text))
{
r = new Run();
PositionalTab positionalTab1 = new PositionalTab() { Alignment = AbsolutePositionTabAlignmentValues.Center,
RelativeTo = AbsolutePositionTabPositioningBaseValues.Margin,
Leader = AbsolutePositionTabLeaderCharValues.None };
r.Append(positionalTab1);
paragraph2.Append(r);
r = new Run(new Text(text) { Space = SpaceProcessingModeValues.Preserve });
paragraph2.Append(r);
}
r = new Run();
PositionalTab positionalTab2 = new PositionalTab() { Alignment = AbsolutePositionTabAlignmentValues.Right,
RelativeTo = AbsolutePositionTabPositioningBaseValues.Margin,
Leader = AbsolutePositionTabLeaderCharValues.None };
r.Append(positionalTab2);
paragraph2.Append(r);
r = new Run(new Text("Page: ") { Space = SpaceProcessingModeValues.Preserve },
// *** Adaptation: This will output the page number dynamically ***
new SimpleField() { Instruction = "PAGE" },
new Text(" of ") { Space = SpaceProcessingModeValues.Preserve },
// *** Adaptation: This will output the number of pages dynamically ***
new SimpleField() { Instruction = "NUMPAGES" });
paragraph2.Append(r);
footer1.Append(paragraph2);
footerPart1.Footer = footer1;
}

Apply style on Content Control in a Word Document using OpenXML

I'm trying to generate Word documents using OpenXML SDK and Word Document Generator. I need to apply my custom style on ContentControls (Repeating Section).
For Recursive Placeholders, I use
foreach (var item in list)
{
var datacontext = new OpenXmlElementDataContext()
{
Element = openXmlElementDataContext.Element,
DataContext = item.Value
};
var clonedElement = CloneElementAndSetContentInPlaceholders(datacontext);
SetContentOfContentControl(clonedElement, item.Value);
}
openXmlElementDataContext.Element.Remove();
I need to apply my style on this element. How to I can do ?
I try to see generated code with "Open XML SDK 2.5 Productivity Tool for Microsoft Office" to inspire me:
var moduleDatacontext = new OpenXmlElementDataContext()
{
Element = openXmlElementDataContext.Element,
DataContext = module.Valeur
};
var moduleClonedElement = CloneElementAndSetContentInPlaceholders(moduleDatacontext);
var sdtProperties1 = new SdtProperties();
var styleId1 = new StyleId() { Val = "FormationTitre2" };
ParagraphMarkRunProperties paragraphMarkRunProperties1 = new ParagraphMarkRunProperties();
RunFonts runFonts1 = new RunFonts() { ComplexScriptTheme = ThemeFontValues.MinorHighAnsi };
paragraphMarkRunProperties1.Append(runFonts1);
sdtProperties1.Append(styleId1);
sdtProperties1.Append(paragraphMarkRunProperties1);
Run run1 = new Run() { RsidRunProperties = "00C463E5" };
RunProperties runProperties1 = new RunProperties();
RunFonts runFonts2 = new RunFonts() { ComplexScriptTheme = ThemeFontValues.MinorHighAnsi };
runProperties1.Append(runFonts2);
run1.Append(runProperties1);
moduleClonedElement.Append(sdtProperties1);
moduleClonedElement.Append(run1);
When I open the generated document, I have this error :
We're sorry. We can't open "...docx" because we found a problem with its contents.
I validate the document and I can see 15 errors:
Full Size

I've found the solution. I search first paragraph and apply my custom style on it.
// clone element
var clonedElement = CloneElementAndSetContentInPlaceholders(datacontext);
// search the first created paragraph on my clonedElement
Paragraph p = clonedElement.Descendants<Paragraph>().FirstOrDefault();
if (p != null)
p.PrependChild<ParagraphProperties>(new ParagraphProperties());
// get the paragraph properties
ParagraphProperties pPr = p.Elements<ParagraphProperties>().First();
// apply style
pPr.ParagraphStyleId = new ParagraphStyleId { Val = "FormationTitre2" };
// set content of content control
SetContentOfContentControl(clonedElement, item.Value);

how can I change the font open xml

How can I change the font family of the document via OpenXml ?
I tried some ways but, when I open the document, it's always in Calibri
Follow my code, and what I tried.
The Header Builder I think is useless to post
private static void BuildDocument(string fileName, List<string> lista, string tipo)
{
using (var w = WordprocessingDocument.Create(fileName, WordprocessingDocumentType.Document))
{
var mp = w.AddMainDocumentPart();
var d = new DocumentFormat.OpenXml.Wordprocessing.Document();
var b = new Body();
var p = new DocumentFormat.OpenXml.Wordprocessing.Paragraph();
var r = new Run();
// Get and format the text.
for (int i = 0; i < lista.Count; i++)
{
Text t = new Text();
t.Text = lista[i];
if (t.Text == " ")
{
r.Append(new CarriageReturn());
}
else
{
r.Append(t);
r.Append(new CarriageReturn());
}
}
// What I tried
var rPr = new RunProperties(new RunFonts() { Ascii = "Arial" });
lista.Clear();
p.Append(r);
b.Append(p);
var hp = mp.AddNewPart<HeaderPart>();
string headerRelationshipID = mp.GetIdOfPart(hp);
var sectPr = new SectionProperties();
var headerReference = new HeaderReference();
headerReference.Id = headerRelationshipID;
headerReference.Type = HeaderFooterValues.Default;
sectPr.Append(headerReference);
b.Append(sectPr);
d.Append(b);
// Customize the header.
if (tipo == "alugar")
{
hp.Header = BuildHeader(hp, "Anúncio Aluguel de Imóvel");
}
else if (tipo == "vender")
{
hp.Header = BuildHeader(hp, "Anúncio Venda de Imóvel");
}
else
{
hp.Header = BuildHeader(hp, "Aluguel/Venda de Imóvel");
}
hp.Header.Save();
mp.Document = d;
mp.Document.Save();
w.Close();
}
}

In order to style your text with a specific font follow the steps listed below:
Create an instance of the RunProperties class.
Create an instance of the RunFont class. Set the Ascii property to the desired font familiy.
Specify the size of your font (half-point font size) using the FontSize class.
Prepend the RunProperties instance to your run containing the text to style.
Here is a small code example illustrating the steps described above:
private static void BuildDocument(string fileName, List<string> text)
{
using (var wordDoc = WordprocessingDocument.Create(fileName, WordprocessingDocumentType.Document))
{
var mainPart = wordDoc.AddMainDocumentPart();
mainPart.Document = new Document();
var run = new Run();
foreach (string currText in text)
{
run.AppendChild(new Text(currText));
run.AppendChild(new CarriageReturn());
}
var paragraph = new Paragraph(run);
var body = new Body(paragraph);
mainPart.Document.Append(body);
var runProp = new RunProperties();
var runFont = new RunFonts { Ascii = "Arial" };
// 48 half-point font size
var size = new FontSize { Val = new StringValue("48") };
runProp.Append(runFont);
runProp.Append(size);
run.PrependChild(runProp);
mainPart.Document.Save();
wordDoc.Close();
}
}
Hope, this helps.

If you are using Stylesheet just add an instance of FontName property at appropriate font index during Fonts initilaization.
private Stylesheet GenerateStylesheet()
{
Stylesheet styleSheet = null;
Fonts fonts = new Fonts(
new Font( // Index 0 - default
new FontSize() { Val = 8 },
new FontName() { Val = "Arial"} //i.e. or any other font name as string
);
Fills fills = new Fills( new Fill(new PatternFill() { PatternType = PatternValues.None }));
Borders borders = new Borders( new Border() );
CellFormats cellFormats = new CellFormats( new CellFormat () );
styleSheet = new Stylesheet(fonts, fills, borders, cellFormats);
return styleSheet;
}
Then use it in Workbook style part as below.
WorkbookStylesPart stylePart = workbookPart.AddNewPart<WorkbookStylesPart>();
stylePart.Stylesheet = GenerateStylesheet();
stylePart.Stylesheet.Save();
