How to find and replace text with content control in Word document?

Platform: ASP.NET Core - EJ 2 |
Control: DocIO

Syncfusion Essential DocIO is a .NET Core Word library used to create, read, and edit Word documents programmatically without Microsoft Word or Interop dependencies. Using this library, you can find and replace text with content control in the Word document in C#.

Steps to find and replace text with content control in the Word document:

  1. Create a new C# .NET Core console application project. Create .NET Core console application in Visual Studio in ASP.NET Core Word
  2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your .NET Core applications from NuGet.org. Add DocIO.Net.Core NuGet packages of ASP.NET Core Word
  3. Include the following namespace in the Program.cs file:

C#

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;
  1. Use the following code example to find and replace text with content control in the Word document:

C#

using (FileStream inputStream= new FileStream(Path.GetFullPath(@"../../../Data/Input.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
   //Load an existing Word document.
   using (WordDocument document = new WordDocument(inputStream, FormatType.Docx))
   {
       //Create a BlockContentControl.
       BlockContentControl blockContentControl = new BlockContentControl(document, ContentControlType.RichText);
       //Add a new table to the block content control.
       WTable table = blockContentControl.TextBody.AddTable() as WTable;
       //Specify the total number of rows and columns.
       table.ResetCells(1, 2);
       //Get first row of the table.
       WTableRow row = table.Rows[0];
       //Add a new paragraph to the first cell of the table.
       IWParagraph cellParagraph= row.Cells[0].AddParagraph();
       row.Cells[0].CellFormat.VerticalAlignment = VerticalAlignment.Top;
       FileStream imageStream = new FileStream(Path.GetFullPath(@"../../../Data/image.png"), FileMode.Open, FileAccess.ReadWrite);
       //Append a picture to the cell.
       WPicture picture = cellParagraph.AppendPicture(imageStream) as WPicture;
       picture.Height = 88.3f;
       picture.Width = 142.2f;
       //Add a new paragraph to the next cell.
       cellParagraph = row.Cells[1].AddParagraph();
       row.Cells[1].CellFormat.VerticalAlignment = VerticalAlignment.Top;
       cellParagraph.ParagraphFormat.BeforeSpacing = 12f;
       //Append text to the cell.
       IWTextRange text = cellParagraph.AppendText("Mountain-200");
       cellParagraph.ParagraphFormat.AfterSpacing = 3f;
       //Set the text format.
       text.CharacterFormat.Bold = true;
       text.CharacterFormat.FontName = "Arial";
       text.CharacterFormat.FontSize = 16f;
       //Add a new paragraph.
       cellParagraph = row.Cells[1].AddParagraph();
       //Append text to the paragraph of a cell.
       cellParagraph.AppendText("Product No: BK-M68B-38 \nSize: 38\nWeight: 25\nPrice: $2,294.99\n\n ");
       //Specify the table borders border type.
       table.TableFormat.Borders.BorderType = BorderStyle.Single;
       //Create a textbody part object.
       TextBodyPart textBodyPart = new TextBodyPart(document);
       //Add the block content control to the textbodyPart.
       textBodyPart.BodyItems.Add(blockContentControl);
       //Replace all entries of a given regular expression with the text body part.
       document.Replace(new Regex("<<(.*)>>"), textBodyPart);
       //Create a file stream.
       using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"../../../Sample.docx"), FileMode.Create, FileAccess.ReadWrite))
       {
           //Save the Word document to the file stream.
           document.Save(outputFileStream, FormatType.Docx);
       }
   }
}
