How to Replace List Paragraph Text in Core Word Document?

Syncfusion® Essential® DocIO is a .NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can replace list paragraph text with multiple paragraphs from another Word document using C#.

To achieve this, follow the steps below:

• Find the list paragraph text in the destination Word document.
• Get all the paragraphs from the source document.
• Replace the found text in the destination with the first paragraph text from the source document.
• Insert the remaining paragraphs from the source document immediately after the replaced text in the destination document.

Steps to replace list paragraph text with multiple paragraphs from another Word document:

1. Create a new .NET Core console application project.
2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org.
   
   

3. Include the following namespaces in Program.cs file
   C#

using Syncfusion.DocIO.DLS;
using Syncfusion.DocIO;
using System.IO;

4. Use the following code example to replace list paragraph text with multiple paragraphs from another Word document.
   C#

using (FileStream destDocStream = new FileStream(Path.GetFullPath(@"Data/DestinationDocument.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
   //Open the destination Word document.
   using (WordDocument destDocument = new WordDocument(destDocStream, FormatType.Docx))
   {
       using (FileStream sourceDocStream = new FileStream(Path.GetFullPath(@"Data/SourceDocument.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
       {
           //Open the source Word document.
           using (WordDocument sourceDocument = new WordDocument(sourceDocStream, FormatType.Docx))
           {
               //Find the text "[finder]" in the destination document.
               TextSelection textSelection = destDocument.Find("[finder]", false, false);
               if (textSelection != null)
               {
                   //Get the paragraph containing the found text in destintaion document.
                   WParagraph destOwnerParagraph = textSelection.GetAsOneRange().OwnerParagraph;
                   //Get the owner section.
                   WSection destOwnerSection = destOwnerParagraph.OwnerTextBody.Owner as WSection;
                   //Get the owner paragraph index.
                   int destOwnerParaIndex = destOwnerSection.Paragraphs.IndexOf(destOwnerParagraph);
                   //Retrieve the first section of the source document.
                   WSection section = sourceDocument.Sections[0];
                   //Iterate through the each paragraph of the source document.
                   for (int i = 0; i < section.Paragraphs.Count; i++)
                   {
                       WParagraph sourcePara = section.Paragraphs[i];
                       //Replace the found text with the first paragraph text from the source document.
                       if (i == 0)
                           destOwnerParagraph.Replace(textSelection.SelectedText, sourcePara.Text, false, false);
                       //For remaining paragraphs in the source document.
                       else
                       {
                           //Clone the found destination paragraph.
                           WParagraph paraToInsert = (WParagraph)destOwnerParagraph.Clone();
                           //Change the paragraph text to the source paragraph text.
                           paraToInsert.Text = sourcePara.Text;
                           //Insert the cloned paragraph as the next item of the found destination paragraph.
                           destOwnerSection.Body.ChildEntities.Insert(destOwnerParaIndex, paraToInsert);
                       }
                       //Increase the paragraph index to insert the next cloned paragraph in the correct position.
                       destOwnerParaIndex++;
                   }
               }
               //Save the destination Word document.
               using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"Output/Result.docx"), FileMode.Create, FileAccess.ReadWrite))
               {
                   //Saves the Word document to file stream.
                   destDocument.Save(outputFileStream, FormatType.Docx);
               }
           }
