{{% alert color="grey" %}}

## Purpose Summary

This page describes how to find and replace text in Word documents with various matching options.

{{% /alert %}}

{{% alert color="primary" %}}

See more details in the [Find and Replace](/words/net/find-and-replace/) article.

{{% /alert %}}

Use one of the [Replace](https://reference.aspose.com/words/net/aspose.words/range/replace/#replace/) methods to find or replace a particular string within the current range. It returns the number of replacements made, so it is useful for searching strings without replace. An exception is thrown if a captured or replacement string contains one or more special characters: paragraph break, cell break, section break, field start, field separator, field end, inline picture, drawing object, footnote.

The following code example shows how to find some text and replace it:

{{< highlight csharp >}}
Document doc = new Document("../../data/document.doc");

// Replaces all 'sad' and 'mad' occurrences with 'bad'.
doc.Range.Replace("document", "document replaced", false, true);

// Replaces all 'sad' and 'mad' occurrences with 'bad'.
doc.Range.Replace(new Regex("[s | m]ad"), "bad");
doc.Save("replacedDocument.doc");
{{< /highlight >}}
