How to find and replace the placeholder with an incremental value in a Word document?

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 the placeholder with an incremental counter in a Word document in C#.

Steps to find and replace the placeholder with an incremental counter in a Word document using C#

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

C#

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;

4. Use the following code example to find and replace placeholder with an incremental counter in a Word document in C#.

C#

using (FileStream fileStreamPath = new FileStream(Path.GetFullPath(@"../../../Input.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
   //Open an existing Word document.
   using (WordDocument document = new WordDocument(fileStreamPath, FormatType.Automatic))
   {
        //Find all occurrence of the Word "{counter}" in the document.
        TextSelection[] textSelection = document.FindAll("{counter}", false, false);
        //Iterate through each occurrence and change the text as an incremental value.
        int counter = 1;
        foreach (TextSelection selection in textSelection)
        {
            IWTextRange textRange = selection.GetAsOneRange();
            textRange.Text = counter.ToString();
            counter++;
        }
        //Create file stream.
        using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"../../../Sample.docx"), FileMode.Create, FileAccess.ReadWrite))
        {
            //Save the Word document to file stream.
            document.Save(outputFileStream, FormatType.Docx);
        }               
   }
}
