- Get the format of the text box using TextBox.Format property, and then set the text box's wrapping type, position, border color and fill color using the properties of TextBoxFormat Class.
- Add a paragraph to the text box using TextBox.Body.AddParagraph() method, and then set its alignment.
- Insert an image to the paragraph using Paragraph.AppendPicture() method, and then set the size of the inserted image.
- Insert text to the text box using Paragraph.AppendText() method, and then set the text font.
- Save the document to another file using Document.SaveToFile() method.

namespace InsertTextbox
{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document document = new Document();
//Load a sample Word document
document.LoadFromFile("Ralph.docx");
//Insert a textbox and set its wrapping style
TextBox TB = document.Sections[0].AddParagraph().AppendTextBox(130, 320);
TB.Format.TextWrappingStyle = TextWrappingStyle.Square;
//Set the position of the textbox
TB.Format.HorizontalOrigin = HorizontalOrigin.RightMarginArea;
TB.Format.HorizontalPosition = -100;
TB.Format.VerticalOrigin = VerticalOrigin.Page;
TB.Format.VerticalPosition = 130f;
//Set the border style and fill color of the textbox
TB.Format.LineColor = Color.DarkBlue;
TB.Format.FillColor = Color.LightCyan;
//Insert an image to textbox as a paragraph
Paragraph para = TB.Body.AddParagraph();
DocPicture picture = para.AppendPicture(@"C:\Users\Administrator\Desktop\Ralph.jpg");
//Set alignment for the paragraph
para.Format.HorizontalAlignment = HorizontalAlignment.Center;
//Set the size of the inserted image
picture.Height = 90;
picture.Width = 90;
//Insert text to textbox as the second paragraph
TextRange TR = para.AppendText("Emerson is truly the center of the American transcendental movement, "
+ "setting out most of its ideas and values in a little book, Nature, published in 1836, "
+ "that represented at least ten years of intense study in philosophy, religion, and literature.");
//Set alignment for the paragraph
para.Format.HorizontalAlignment = HorizontalAlignment.Center;
//Set the font of the text
TR.CharacterFormat.FontName = "Times New Roman";
TR.CharacterFormat.FontSize = 12;
TR.CharacterFormat.Italic = true;
//Save the result file
document.SaveToFile("AddTextBox.docx", FileFormat.Docx);
}
