Spire.Cloud.Word provides the ParagraphsApi interface which is used for handling paragraphs in Word documents. This article introduces how to add, remove or edit a paragraph in an existing Word document.

Example 1. Add a paragraph

using Spire.Cloud.Word.Sdk.Api;
using Spire.Cloud.Word.Sdk.Client;
using System;

namespace CloudAddParagraph
{
    class Program
    {
        static string appId = "App ID";
        static string appKey = "App Key";
        static string baseUrl = "https://api.cloudxdocs.com";

        //Create a Configuration object based on App ID, App Key and base URL
        static Configuration configuration = new Configuration(appId, appKey, baseUrl);

        //Create a ParagraphsApi object
        static ParagraphsApi paragraphsApi = new ParagraphsApi(configuration);

        static void Main(string[] args)
        {
            //Specify the source document name
            string fileName = "sample.docx";

            //Specify the section and body to insert paragraph
            string nodePath = "Section/0/Body/0";

            //Specify the path and name of the generated document
            string destFilePath = "output/AddParagraph.docx";

            //Specify the folder where the source document is stored
            string folder = "input";

            //Use the default storage, set to null
            string storage = null;

            //Specify the index where the new paragraph will be inserted
            int indexOfParagraph = 2;

            //Specify the open password of the source document, set to null if there’s no password
            string password = null;

            //Specify the text of the new paragraph
            string text = "This is a new paragraph.";

            //Call AddParagraph method to insert a new paragraph
            paragraphsApi.AddParagraph(fileName, nodePath, destFilePath, folder, storage, indexOfParagraph, password, text);         
        }
    }
}

Example 2. Remove a paragraph

using Spire.Cloud.Word.Sdk.Api;
using Spire.Cloud.Word.Sdk.Client;
using System;

namespace CloudDeleteParagraph
{
    class Program
    {
        static string appId = "App ID";
        static string appKey = "App Key";
        static string baseUrl = "https://api.cloudxdocs.com";

        //Create a Configuration object based on App ID, App Key and base URL
        static Configuration configuration = new Configuration(appId, appKey, baseUrl);

        //Create a ParagraphsApi object
        static ParagraphsApi paragraphsApi = new ParagraphsApi(configuration);

        static void Main(string[] args)
        {
            //Specify the source document name
            string fileName = "sample.docx";

            //Specify the section and body
            string nodePath = "Section/0/Body/0";

            //Specify the index of the paragraph that'll be deleted
            int? index = 0;

            //Specify the path and name of the generated document
            string destFilePath = "output/DeleteParagraph.docx";

            //Specify the folder where the source document is stored
            string folder = "input";

            //Use the default storage, set to null
            string storage = null;

            //Specify the open password of the source document, set to null if there’s no password
            string password = null;

            //Call DeleteParagraph method to delete the specific paragraph
            paragraphsApi.DeleteParagraph(fileName, nodePath, index, destFilePath, folder, storage, password);
        }
    }
}

Example 3. Edit a pragraph

using Spire.Cloud.Word.Sdk.Api;
using Spire.Cloud.Word.Sdk.Client;
using System;

namespace CloudEditParagraph
{
    class Program
    {
        static string appId = "App ID";
        static string appKey = "App Key";
        static string baseUrl = "https://api.cloudxdocs.com";

        //Create a Configuration object based on App ID, App Key and base URL
        static Configuration configuration = new Configuration(appId, appKey, baseUrl);

        //Create a ParagraphsApi object
        static ParagraphsApi paragraphsApi = new ParagraphsApi(configuration);

        static void Main(string[] args)
        {
            //Specify the source document name
            string fileName = "sample.docx";

            //Specify the section and body
            string nodePath = "Section/0/Body/0";

            //Specify the index of the paragraph that'll be updated
            int? index = 0;

            //Specify new text
            string text = "This is the updated paragraph";

            //Specify the path and name of the generated document
            string destFilePath = "output/EditParagraph.docx";

            //Specify the folder where the source document is stored
            string folder = "input";

            //Use the default storage, set to null
            string storage = null;

            //Specify the open password of the source document, set to null if there's no password
            string password = null;

            //Call UpdateParagraphText method to replace text of an existing paragraph
            paragraphsApi.UpdateParagraphText(fileName, nodePath, index, text, destFilePath, folder, storage, password);
        }
    }
