Loading Specific File Formats

Introduction

In the world of .NET development, parsing and extracting text from various file formats is a common requirement. GroupDocs.Parser for .NET offers powerful tools to simplify this task. This tutorial will guide you through using GroupDocs.Parser to load and extract text from specific file formats step by step.

Prerequisites

Before diving into this tutorial, ensure you have the following:

• Basic knowledge of C# and .NET development.
• Visual Studio or another IDE for .NET development installed.
• GroupDocs.Parser for .NET library. You can download it from here.
• A sample file in one of the supported formats (e.g., Word, PDF, Markdown).

Import Namespaces

Start by adding the necessary namespaces to your C# file:

using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
using GroupDocs.Parser.Options;

Follow these steps to load and extract text from a specific file format:

Step 1: Open a File Stream

First, open a stream to your sample file:

using (Stream stream = File.OpenRead("YourSampleFile.docx"))
{
    // Proceed to next step
}

Replace "YourSampleFile.docx" with the path to your sample file.

Step 2: Create a Parser Instance

Instantiate the Parser class with the opened stream and specify the file format:

using (Parser parser = new Parser(stream, new LoadOptions(FileFormat.Docx)))
{
    // Proceed to next step
}

Replace FileFormat.Docx with the appropriate file format enumeration based on your sample file (e.g., FileFormat.Pdf, FileFormat.Markup for Markdown).

Step 3: Check Text Extraction Support

Verify if text extraction is supported for the loaded file format:

if (!parser.Features.Text)
{
    Console.WriteLine("Text extraction isn't supported.");
    return;
}

Step 4: Extract Text from Document

Use parser.GetText() to obtain a TextReader instance and read the extracted text:

using (TextReader reader = parser.GetText())
{
    string extractedText = reader.ReadToEnd();
    Console.WriteLine(extractedText);
}
