Load Document

Introduction

Editing documents programmatically can be a daunting task, especially if you’re dealing with different file formats and complex structures. Luckily, GroupDocs.Editor for .NET makes this task a breeze, providing a robust and easy-to-use API for editing a wide range of document types. In this tutorial, we’ll walk you through everything you need to get started with GroupDocs.Editor for .NET, including the prerequisites, how to import namespaces, and a detailed, step-by-step guide to loading documents using various methods.

Prerequisites

Before we dive in, make sure you have the following prerequisites set up:

  • Visual Studio: Ensure you have Visual Studio installed on your machine.
  • .NET Framework: GroupDocs.Editor for .NET supports .NET Framework 2.0 or later. Ensure your project is targeting a compatible framework.
  • GroupDocs.Editor for .NET: Download the latest version from the download page.
  • Basic Knowledge of C#: Familiarity with C# and .NET programming is necessary to follow along with this tutorial.

Import Namespaces

To begin using GroupDocs.Editor for .NET, you need to import the necessary namespaces into your project. Add the following using directives at the top of your C# file:

using GroupDocs.Editor.Options;
using System.IO;

These namespaces will provide access to the classes and methods required for document editing tasks.

Step 1: Load Document from a File Path

Loading a document from a file path is straightforward. This method is ideal for documents stored locally on your machine.

string inputPath = "Your Sample Document";
// Load document as file via path and without load options
Editor editor1 = new Editor(inputPath);
// Dispose resources
editor1.Dispose();
System.Console.WriteLine("Document loaded successfully from file path.");

Step 2: Load Document with Load Options

Sometimes, you may need to load documents that require special handling, such as password-protected files. In such cases, you can use load options.

string inputPath = "Your Sample Document";
// Create load options for Word documents
WordProcessingLoadOptions wordLoadOptions = new WordProcessingLoadOptions();
wordLoadOptions.Password = "some password";
// Load document as file via path and with load options
Editor editor2 = new Editor(inputPath, delegate { return wordLoadOptions; });
// Dispose resources
editor2.Dispose();
System.Console.WriteLine("Password-protected document loaded successfully.");

Step 3: Load Document from a Byte Stream

Loading a document from a byte stream is useful when you need to process documents that are not stored as files, such as those retrieved from a database or a web service.

FileStream inputStream = File.OpenRead("Your Sample Document");
// Load document as content from byte stream and without load options
Editor editor3 = new Editor(delegate { return inputStream; });
// Dispose resources
editor3.Dispose();
System.Console.WriteLine("Document loaded successfully from byte stream.");

Step 4: Load Document with Load Options from a Byte Stream

For documents requiring special handling when loaded from a byte stream, you can combine byte stream loading with load options.

FileStream inputStream = File.OpenRead("Your Sample Document");
// Create load options for spreadsheets
SpreadsheetLoadOptions sheetLoadOptions = new SpreadsheetLoadOptions();
sheetLoadOptions.OptimizeMemoryUsage = true;
// Load document as content from byte stream and with load options
Editor editor4 = new Editor(delegate { return inputStream; }, delegate { return sheetLoadOptions; });
// Dispose resources
editor4.Dispose();
System.Console.WriteLine("Spreadsheet document loaded successfully with load options.");
