Opdel tekstfil i mange filer i C# .NET

Brug tekstsplitterbibliotek til .NET-applikationer – opdel hver linje eller flere linjer i kildetekstfilen i en separat resulterende .txt-fil ved at bruge et par linjer C#-kode.

Initialiser TextSplitOptions-klassen med outputfilstiformat, ønsket TextSplitMode og linjenumre
Instantiér Merger-objekt med kildedokumentsti eller strøm
Kald Split-metoden og send TextSplitOptions-objektet for at gemme de resulterende tekstfiler

Enkeltdokumentændringsoperationer

Udfør multifunktionelle dokumentmanipulationsfunktioner i en række dokumentformater såsom Word, Excel-regneark, præsentationer, RTF, PDF, Visio, HTML, OneNote, XPS og mange andre ved at tilføje blot et par linjer C#-kode.

De vigtigste enkeltdokumenthandlinger omfatter flytning af sider i et dokument til en ny position, fjernelse af en enkelt side eller en samling eller udvalgte sider, udskiftning af sidepositioner, udtrækning af bestemte sider fra dokumentet, ændring af sideretningen til stående eller liggende tilstand og rotation siderne i kildedokumentet til en vinkel på 90, 180 eller 270 grader.

	string filePath = @"c:\sample.txt";
	string filePathOut = @"c:\output\line_{0}.{1}";

	TextSplitOptions splitOptions = new TextSplitOptions(filePathOut, new int[] { 3, 6 });

	using (Merger merger = new Merger(filePath))
	{
	merger.Split(splitOptions);

What is PDF file format?

PDF (Portable Document Format) is a widely used document file format developed by Adobe Systems in 1993. It was specifically designed to provide a platform-independent solution for storing and sharing documents across various operating systems and over the Internet. PDFs utilize a vector-based drawing model, storing graphical elements such as lines, shapes, and images as mathematical equations. This unique approach ensures that PDFs are resolution independent, guaranteeing consistent document quality regardless of the viewing device or program.

One of the key advantages of PDFs is their support for a range of security features. Encryption, password protection, digital signatures, and document watermarking are among the security measures available. These features make PDFs highly secure and suitable for sensitive documents, such as medical records, legal documents, government forms, and invoices. The printing industry also heavily relies on PDFs to facilitate electronic communication with customers.

Creating PDFs is a straightforward process, as they can be generated from various electronic document formats, including Word documents, PowerPoint presentations, and webpages. It’s important to note that PDFs are typically not editable directly. To modify the content of a PDF, it must first be converted to a different file format that supports editing. Numerous software programs, many of which are freely available for download, offer the functionality to convert PDFs to editable formats.

PDFs have gained immense popularity and have become a standard method for document sharing due to their versatility, security features, and consistent formatting. Their compatibility across different devices and operating systems ensures seamless document access for users. Additionally, PDFs preserve the layout, fonts, and images of the original document, making them an ideal choice for sharing visually rich content.
