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"
};

amazonS3client.SelectObjectContentAsync - downloading the large jsonline formate file - unwanted line break

I am trying to download a file content from the S3 bucket using the SelectObjectContentAsync method from AWSSDK for C#.
But there are some unwanted line break(\n) in mid of the raw data.
Data Example :
{"Id":1,"Name":"aaa"}, {"Id":2,"N
\name":"bbb"}
My Code :
var amazonS3Client = new AmazonS3Client(awsAccessKeyId, awsSecretAccessKey, region);
SelectObjectContentRequest selectObjectContentRequest = new SelectObjectContentRequest()
{
Bucket = bucketName,
Key = key,
ExpressionType = ExpressionType.SQL,
Expression = query,
InputSerialization = new InputSerialization()
{
JSON = new JSONInput()
{
JsonType = JsonType.Lines
},
CompressionType = CompressionType.Gzip
},
OutputSerialization = new OutputSerialization()
{
JSON = new JSONOutput()
{
RecordDelimiter = ","
}
}
};
using (var content = amazonS3Client.SelectObjectContentAsync(selectObjectContentRequest).Result.Payload)
{
foreach (var item in content)
{
if (item is RecordsEvent recordsEvent)
{
using (var reader = new StreamReader(recordsEvent.Payload, Encoding.UTF8))
{
using (var file = new StreamWriter(path, true))
{
file.WriteLine(reader.ReadToEnd());
}
}
}
}
}

PDFBox doesn't embedd all Fonts

i'm using PDFBox in C# Project to create PDF/A and PDF/A3. Almost everything is working except that when I use PDFBox to convert a normal PDF-File to PDF/A not all Fonts are embedded. If I use Word to save as PDF/A the Font in Question is embedded. How do I embedd ArialMT too?
private PDDocumentCatalog makeDocPDFAcompliant(String producer, String creator)
{
PDDocumentCatalog cat = doc.getDocumentCatalog();
PDMetadata metadata = new PDMetadata(doc);
cat.setMetadata(metadata);
List<Dictionary<string, PDFont>> lstFonts = new List<Dictionary<string, PDFont>>();
List<PDFont> lstPDFonts= new List<PDFont>();
List pages = cat.getAllPages();
Iterator it = pages.iterator();
while (it.hasNext())
{
PDPage page = (PDPage)it.next();
var pageFont = page.getResources().getFonts();
lstFonts.Add(pageFont.ToDicitonary<string, PDFont>());
}
foreach (Dictionary<string, PDFont> d in lstFonts)
{
foreach (KeyValuePair<string, PDFont> entry in d)
{
PDFont font = entry.Value;
if (!lstPDFonts.Contains(font))
{
lstPDFonts.Add(font);
}
}
}
//PDType0Font font0 = PDType0Font.Load(doc,)

Pechkin converting webpage to pdf c# gives empty pdf.

I am exploring Pechkin to convert webpage to PDF. I have used article: http://ourcodeworld.com/articles/read/366/how-to-generate-a-pdf-from-html-using-wkhtmltopdf-with-c-in-winforms
Ref: How to use wkhtmltopdf.exe in ASP.net
When i try to convert using html string, it works !
byte[] pdfContent = new SimplePechkin(new GlobalConfig()).Convert("<html><body><h1>Hello world!</h1></body></html>");
However when I follow "Generate PDF from a Website" section, I get empty pdf.
configuration.SetCreateExternalLinks(false)
.SetFallbackEncoding(Encoding.ASCII)
.SetLoadImages(true)
.SetPageUri("http://ourcodeworld.com");
Has anyone encountered same issue? Appreciate all help/suggestions.

Try to use
https://github.com/tuespetre/TuesPechkin
var document = new HtmlToPdfDocument
{
GlobalSettings =
{
ProduceOutline = true,
DocumentTitle = "Pretty Websites",
PaperSize = PaperKind.A4, // Implicit conversion to PechkinPaperSize
Margins =
{
All = 1.375,
Unit = Unit.Centimeters
}
},
Objects = {
new ObjectSettings { HtmlText = "<h1>Pretty Websites</h1><p>This might take a bit to convert!</p>" },
new ObjectSettings { PageUrl = "www.google.com" },
new ObjectSettings { PageUrl = "www.microsoft.com" },
new ObjectSettings { PageUrl = "www.github.com" }
}
};
var tempFolderDeployment = new TempFolderDeployment();
var win32EmbeddedDeployment = new Win32EmbeddedDeployment(tempFolderDeployment);
var remotingToolset = new RemotingToolset<PdfToolset>(win32EmbeddedDeployment);
var converter = ThreadSafeConverter(remotingToolset);
byte[] pdfBuf = converter.Convert(document);
// Very important - overwise cpu will grow !!!
remotingToolset.Unload();

Filtering by .docx in ios document picker

What is the Uniform Type Identifer to provide to a UIDocumentMenuViewController to allow a user to select *.docx files?
The documentation in System-Declared Uniform Type Identifiers does not list a public UTType that allows filtering by .docx. An identifier exists for a standard *.doc file but not *.docx, is there instead an alternate UTType?
This is my current code:
var allowedDocumentTypes = new string[] {
UTType.RTF,
UTType.Text,
UTType.PDF,
UTType.UTF8PlainText,
UTType.RTFD,
UTType.UTF16ExternalPlainText,
UTType.UTF16PlainText,
UTType.UTF8PlainText,
UTType.FlatRTFD,
"com.microsoft.word.doc",
"com.microsoft.word.docx" // An attempt to include docx filtering.
};
var pickerMenu = new UIDocumentMenuViewController(allowedDocumentTypes, UIDocumentPickerMode.Open);
pickerMenu.DidPickDocumentPicker += (sender, args) =>
{
args.DocumentPicker.DidPickDocument += (sndr, pArgs) =>
{
var securityEnabled = pArgs.Url.StartAccessingSecurityScopedResource();
FileInfo fi = new FileInfo(pArgs.Url.Path);
var result = new SelectFileResult();
result.FilePath = fi.FullName;
result.FileName = fi.Name;
NSUrlRequest urlReq = NSUrlRequest.FromUrl(pArgs.Url);
NSUrlResponse response;
NSError error;;
var data = NSUrlConnection.SendSynchronousRequest(urlReq, out response, out error);
result.MimeType = response.MimeType;
Action onFileConsumeDone = () =>
{
pArgs.Url.StopAccessingSecurityScopedResource();
};
onFileSelected(result, onFileConsumeDone);
};
// Display the document picker
AppDelegate.TopViewController.PresentViewController(args.DocumentPicker, true, null);
};
pickerMenu.ModalPresentationStyle = UIModalPresentationStyle.Popover;
AppDelegate.TopViewController.PresentViewController(pickerMenu, true, null);
I had a shot in the dark and included the identifier com.microsoft.word.docx but it does not trigger filtering by docx.
My current solution is C# but objective-c and swift solutions accepted.

Try org.openxmlformats.wordprocessingml.document

Try
let supportedTypes: [UTType] = [UTType.content]
