  • Load a sample Word document using Document.LoadFromFile() method.
  • Change the text replacement mode to replace the first instance only by setting the Document.ReplaceFirst property to true.
  • Call the Document.Replace(string matchString, string newValue, bool caseSensitive, bool wholeWord) method to replace text.
  • Save the result document using Document.SaveToFile() method.
  • C#
using Spire.Doc;

namespace ReplaceFirstText
{
    internal class Program
    {
        static void Main(string[] args)
        {
            //Instantiate an object of the Document class
            Document document = new Document();
            //Load a sample Word document
            document.LoadFromFile("Sample.docx");

            //Change the text replacement mode to replace the first instance only
            document.ReplaceFirst = true;

            //Replace the first instance of specific text with new text
            document.Replace("Spire.Doc", "Eiceblue", false, true);

            //Save the result document
            document.SaveToFile("ReplaceFirstText.docx", FileFormat.Docx2016);
            document.Close();
        }
    }
}

Find and Replace Text with Image

Sometimes, you may need to replace text with images for visual representation or design purposes. In Spire.Doc for .NET, replacing text with image can be achieved by inserting the image at the position of the target text and then removing the text from the document. The detailed steps are as follows.

  • Instantiate an object of the Document class.
  • Load a sample Word document using Document.LoadFromFile() method.
  • Find specific text in the document using Document.FindAllString() method.
  • Loop through the matched text.
  • For each matched text, get the paragraph where it is located and get the position of the text in the paragraph.
  • Instantiate an object of the DocPicture class, and then load an image using DocPicture.LoadImage() method.
  • Insert the image into the paragraph at the position of the text and then remove the text from the paragraph.
  • Save the result document using Document.SaveToFile() method.
  • C#
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;

namespace ReplaceTextWithImage
{
    internal class Program

            //Instantiate an object of the Document class
            Document document = new Document();
            //Load a sample Word document
            document.LoadFromFile("Sample.docx");

            //Find specific text in the document
            TextSelection[] selections = document.FindAllString("Spire.Doc", true, true);

            int index = 0;
            Paragraph ownerParagraph = null;

            //Loop through the matched text
            foreach (TextSelection selection in selections)
            {
                //Get the paragraph where the text is located
                ownerParagraph = selection.GetAsOneRange().OwnerParagraph;

                //Get the index position of the text in the paragraph
                index = ownerParagraph.ChildObjects.IndexOf(selection.GetAsOneRange());

                //Load an image
                DocPicture pic = new DocPicture(document);
                pic.LoadImage("img.png");

                //Insert the image into the paragraph at the index position of the text
                ownerParagraph.ChildObjects.Insert(index, pic);

                //Remove the text from the paragraph
                ownerParagraph.ChildObjects.Remove(selection.GetAsOneRange());
            }

            //Save the result document
