Load Document from Local Disk

Introduction

In this tutorial, we will explore how to use GroupDocs.Parser for .NET to extract text from documents. GroupDocs.Parser is a powerful library that allows developers to parse various document formats and extract text content programmatically. We’ll cover the necessary steps to get started with text extraction using this library.

Prerequisites

Before we begin, ensure you have the following prerequisites installed:

  • Visual Studio installed on your system.
  • Basic knowledge of C# programming language.
  • GroupDocs.Parser for .NET library installed (download here).

Import Namespaces

First, you need to import the necessary namespaces to your C# project:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;

Step 1: Load Document from Local Disk

Begin by loading a document from your local disk. Replace "Your Sample File" with the path to your target document.

// Set the filePath
string filePath = "Your Sample File";
// Create an instance of Parser class with the filePath
using (Parser parser = new Parser(filePath))
{
    // Extract text into the reader
    using (TextReader reader = parser.GetText())
    {
        // Print the extracted text from the document
        // If text extraction isn't supported, the reader will be null
        Console.WriteLine(reader == null ? "Text extraction isn't supported" : reader.ReadToEnd());
    }
}

Explanation of Steps

  1. Setting File Path: Begin by specifying the path to the document you want to extract text from (filePath variable).
  2. Creating Parser Instance: Instantiate the Parser class by passing the filePath.
  3. Extracting Text: Use the GetText() method of the Parser instance to obtain a TextReader object containing the extracted text from the document.
  4. Reading Extracted Text: Utilize the ReadToEnd() method of the TextReader to retrieve the entire text content extracted from the document.
  5. Handling Unsupported Formats: If the document format does not support text extraction, the reader object will be null, and you can handle this scenario accordingly.

Conclusion

In this tutorial, we’ve covered the initial steps to extract text from a document using GroupDocs.Parser for .NET. This library offers extensive features for document parsing, enabling developers to efficiently work with various file formats within their applications.
