Keep Source Numbering

This tutorial explains how to append a source document to a destination document while preserving the original numbering formatting of numbered paragraphs using Aspose.Words for .NET.

Step 1: Set up the project

Make sure you have the following prerequisites:

• Aspose.Words for .NET library installed. You can download it from [Aspose.Releases]https://releases.aspose.com/words/net/ or use NuGet package manager to install it.
• A document directory path where the source and destination documents will be saved.

Step 2: Create the destination and source documents

Create instances of Document for the destination and source documents.

// Path to your document directory
string dataDir = "YOUR DOCUMENT DIRECTORY";

Document srcDoc = new Document(dataDir + "Document source.docx");
Document dstDoc = new Document(dataDir + "Northwind traders.docx");

Step 3: Keep source numbering when importing

To preserve the numbering formatting of numbered paragraphs from the source document, create an instance of ImportFormatOptions and set KeepSourceNumbering to true. Use a NodeImporter to import nodes from the source document to the destination document, specifying ImportFormatMode.KeepSourceFormatting and the importFormatOptions.

ImportFormatOptions importFormatOptions = new ImportFormatOptions { KeepSourceNumbering = true };
NodeImporter importer = new NodeImporter(srcDoc, dstDoc, ImportFormatMode.KeepSourceFormatting, importFormatOptions);

Step 4: Import and append paragraphs

Iterate through the paragraphs in the source document and import each paragraph into the destination document using the importer. Append the imported nodes to the destination document’s body.

ParagraphCollection srcParas = srcDoc.FirstSection.Body.Paragraphs;
foreach (Paragraph srcPara in srcParas)
{
    Node importedNode = importer.ImportNode(srcPara, false);
    dstDoc.FirstSection.Body.AppendChild(importedNode);
}

Step 5: Save the modified document

Save the modified document using the Save method of the Document object.

dstDoc.Save(dataDir + "JoinAndAppendDocuments.KeepSourceNumbering.docx");

This completes the implementation of appending a source document to a destination document while keeping the original numbering formatting using Aspose.Words for .NET.

Example source code for Keep Source Numbering using Aspose.Words for .NET

	// Path to your document directory 
	string dataDir = "YOUR DOCUMENT DIRECTORY";

	Document srcDoc = new Document(dataDir + "Document source.docx");
	Document dstDoc = new Document(dataDir + "Northwind traders.docx");
	// Keep source list formatting when importing numbered paragraphs.
	ImportFormatOptions importFormatOptions = new ImportFormatOptions { KeepSourceNumbering = true };
	NodeImporter importer = new NodeImporter(srcDoc, dstDoc, ImportFormatMode.KeepSourceFormatting,
		importFormatOptions);
	ParagraphCollection srcParas = srcDoc.FirstSection.Body.Paragraphs;
	foreach (Paragraph srcPara in srcParas)
	{
		Node importedNode = importer.ImportNode(srcPara, false);
		dstDoc.FirstSection.Body.AppendChild(importedNode);
	}
	dstDoc.Save(dataDir + "JoinAndAppendDocuments.KeepSourceNumbering.docx");
