Hello, World!

A “Hello, World!” code is often the first simple example to write uisng “Aspose.Words for .NET”, and it can also be used as a sanity test to ensure the software intended to compile or run source code is correctly installed.

“Aspose.Words for .NET” C# library gives developers direct access to create, modify, merge, convert, compare Word and Web documents. PDF, DOCX, DOC, RTF, ODT, EPUB, HTML and many other file formats are supported.

Below code snippet follows these steps:

4. Open an existing Document from a file. Automatically detects the file format
5. Append document “A” to the and of the document “B”
6. Save the output as PDF

The following code snippet is a “Hello, World!” program to exhibit working of “Aspose.Words for .NET” API:

namespace Aspose.Words.Examples
{
    public class ExampletHelloWorld
    {
        static void Main(string[] args)
        {
            // Create a new empty document A
            Document docA = new Document();

            // Inisialize a DocumentBuilder
            DocumentBuilder builder = new DocumentBuilder(docA);

            // Insert text to the document A start
            builder.MoveToDocumentStart();
            builder.Write("First Hello World paragraph");

            // Open an existing document B
            Document docB = new Document("C:\\Temp\\documentB.docx");

            // Add document B to the and of document A, preserving document B formatting
            docA.AppendDocument(docB, ImportFormatMode.KeepSourceFormatting);

            // Save the output as PDF
            docA.Save("C:\\Temp\\output_AB.pdf");
        }
    }
