using System;
using System.Drawing;
namespace AddCheckbox
{

class Program
{

static void Main(string[] args)
{
//Create a new word document
Document document = new Document();

//Add a section to the document
Section section = document.AddSection();

//Add a document to the section
Paragraph paragraph = section.AddParagraph();

//Add checkbox content control
StructureDocumentTagInline sdt = new StructureDocumentTagInline(document);
paragraph = section.AddParagraph();
sdt = new StructureDocumentTagInline(document);
sdt.CharacterFormat.FontSize = 20;
paragraph.ChildObjects.Add(sdt);
sdt.SDTProperties.SDTType = SdtType.CheckBox;
SdtCheckBox scb = new SdtCheckBox();
sdt.SDTProperties.ControlProperties = scb;
TextRange tr = new TextRange(document);
tr.CharacterFormat.FontName = "MS Gothic";
tr.CharacterFormat.FontSize = 20;
sdt.ChildObjects.Add(tr);
scb.Checked = true;

sdt.SDTProperties.Alias = "CheckoBox";
sdt.SDTProperties.Tag = "Checkbox";

//Add picture content control
paragraph = section.AddParagraph();
sdt = new StructureDocumentTagInline(document);
paragraph.ChildObjects.Add(sdt);
sdt.SDTProperties.ControlProperties = new SdtPicture();

sdt.SDTProperties.Alias = "Picture";
sdt.SDTProperties.Tag = "Picture";

DocPicture pic = new DocPicture(document) { Width = 10, Height = 10 };
pic.LoadImage(Image.FromFile("Logo.jpg"));
sdt.SDTContent.ChildObjects.Add(pic);

document.SaveToFile("Sample.docx", FileFormat.Docx2013);
