Open and read documents in C#

If you want to open a text file and work with the data in plain-text format, you can do it using the most basic features of the C# language and operating system. As for reading office documents, presented in a wide variety of file formats (DOCX, DOC, PDF, RTF, ODT, HTML, etc.), this task is more difficult to solve, since such documents are described by complex tree-like data structures within the DOM model.

Our C# library is a cloud-based solution that will allow you to open documents in any office and web format. This distributed approach gives you flexibility in software development using C# language, as all resource-intensive document processing will take place on Aspose servers. All you need is to get private keys to access Cloud API in C# code.

Programmatically read Word, PDF documents in C#

You can iterate over document elements, or you can search for specific elements in the DOM tree. We provide a wide range of C# functions both for working with the structure of the document and with the data contained in the document nodes.

The following C# code example will help you quickly figure out how to load a document and perform some actions on it.

Upload a document you want to access
Run code
using Aspose.Words.Cloud.Sdk;

var config = new Configuration { ClientId = "####-####-####-####-####", 
   ClientSecret = "##################" };
var wordsApi = new WordsApi(config);
var fileName = "Input.docx";

using var requestFileContent = File.OpenRead(File.ReadAllText(fileName));
var uploadDocumentRequest = new UploadFileRequest(requestFileContent, fileName);
await wordsApi.UploadFile(uploadDocumentRequest);

var requestParagraph = new ParagraphInsert()
{
    Text = "Reading and writing to the file in the cloud occurs automatically."
};
var insertParagraphRequest = new InsertParagraphRequest(fileName, requestParagraph);
await wordsApi.InsertParagraph(insertParagraphRequest);

var downloadDocumentRequest = new DownloadFileRequest(fileName);
await wordsApi.DownloadFile(downloadDocumentRequest);
