How to get the section number of the particular bookmark in C#?

Syncfusion Essential DocIO is a .NET Core Word library used to create, read, and edit Word documents programmatically without Microsoft Word or Interop dependencies. Using this library, you can get the section number of the particular bookmark in C#.

Steps to get the section number of the particular bookmark using C#

1. Create a new C# .NET Core console application project.
2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your .NET Core applications from NuGet.org.
3. Include the following namespace in the Program.cs file:

C#

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;

4. Use the following code example to get the section number of the particular bookmark in C#.

C#

using (FileStream fileStreamPath = new FileStream(Path.GetFullPath(@"../../../Input.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
    //Open an existing Word document.
    using (WordDocument document = new WordDocument(fileStreamPath, FormatType.Automatic))
    {
        // Get the bookmark instance by using FindByName method of BookmarkCollection with bookmark name
        Bookmark bookmark = document.Bookmarks.FindByName("BOOKMARK2");
        if (bookmark != null)
        {
            // Get the owner section of bookmark.
            WSection section = GetOwnerEntity(bookmark.BookmarkStart) as WSection;
            if (section != null)
            {
                // Get the index value of section.
                int sectionIndex = document.ChildEntities.IndexOf(section);
                int sectionNumber = sectionIndex + 1;
                Console.WriteLine("This bookmark would be in section " + sectionNumber);
                Console.ReadKey();
            }
        }
    }                
}

5. Helper method

C#

/// <summary>
/// Get the Entity owner.
/// </summary>
private static Entity GetOwnerEntity(BookmarkStart bookmarkStart)
{
     Entity baseEntity = bookmarkStart.Owner;
 
     while (!(baseEntity is WSection))  
     {
             if (baseEntity is null)
                    return baseEntity;
             baseEntity = baseEntity.Owner;
     }
