In Word, with the help of content control, documents or templates with specific functions can be designed. Several commonly used content controls are briefly introduced in the following table:

Name	brief introduction
Dropdown List Content Control	The drop-down list contains a predefined list. Unlike combo boxes, drop-down lists do not allow users to edit items.
Plain text content control	Plain text content controls can only contain text and cannot contain other items, such as tables, pictures or other content controls.
Rich text content control	Unlike plain text content controls, rich text content controls can contain items other than text, such as tables, pictures, or other content controls.
Date picker content control	The date picker content control contains a calendar control to help users enter dates.
Combo Box Content Control	The combo box control contains a list that can be edited directly. It combines the attributes of text box and drop-down list. Users can enter values in the box or select values from the drop-down list.
Picture Content Control	Picture content controls are used to display pictures. Users can specify pictures when making templates, or they can select pictures to insert by clicking this control.

Method 2: Through Nuget Website download.

 

C# sample code (for reference):

The test documents are as follows:

using Spire.Doc;
using Spire.Doc.Documents;
using System;
using System.Collections.Generic;
using System.Text;

namespace GetSDT

            Document document = new Document();
            document.LoadFromFile("test.docx");

            //call StructureTags Class Gets a List of Content Controls
            StructureTags structureTags = GetAllTags(document);
            List<StructureDocumentTagInline> tagInlines = structureTags.tagInlines;

            //Get the content control properties and output them to the console
            for (int i = 0; i < tagInlines.Count; i++)
            {
                string alias = tagInlines[i].SDTProperties.Alias;
                string tag = tagInlines[i].SDTProperties.Tag;
