Using the OpenXmlDocument Class

Now, we can write a small program to use our new class, to dump the relationships to the console:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Examples.LtxOpenXml;

class Program
{
    static void DumpRelationships(List<Relationship> source, int indentLevel)
    {
        string indent = "".PadRight(indentLevel * 2);

        foreach (var r in source)
        {
            Console.WriteLine("{0}Id: {1}",
                indent, r.Id);
            Console.WriteLine("{0}RelationshipType: {1}",
                indent, r.RelationshipType);
            Console.WriteLine("{0}ContentType: {1}",
                indent, r.ContentType);
            Console.WriteLine("{0}SourceUri: {1}",
                indent, r.SourceUri);
            Console.WriteLine("{0}TargetUri: {1}",
                indent, r.TargetUri);
            Console.WriteLine("{0}TargetMode: {1}",
                indent, r.TargetMode);
            if (r.XDocument != null)
                Console.WriteLine("{0}XDocument descendant node count: {1}",
                    indent, r.XDocument.DescendantNodes().Count());
            Console.WriteLine();
            if (r.Relationships != null)
                DumpRelationships(r.Relationships, indentLevel + 1);
        }
    }

    static void Main(string[] args)
    {
        string filename = "OfficeXMLMarkupExplained_en.docx";
        //string filename = "Test.docx";
        //string filename = "Book1.xlsx";

        using (OpenXmlDocument doc = new OpenXmlDocument(filename))
        {
            Console.WriteLine("Document Name: {0}", doc.Name);
            Console.WriteLine();
            DumpRelationships(doc.Relationships, 0);
        }
    }
}

This code produces very similar output to the first example.
