Implementation Guide

Now that GroupDocs.Redaction is set up, let’s implement saving a redacted document while preserving its original format.

Creating and Configuring Redactor

Overview: The Redactor class is central to applying redactions. It allows you to load documents and apply various modifications.

Step 1: Initialize the Redactor

Create an instance of the Redactor class with your document’s file path:

string sourceFile = "YOUR_DOCUMENT_DIRECTORY"; // Replace with actual path.
using (Redactor redactor = new Redactor(sourceFile))
{
    ...
}

Step 2: Apply Exact Phrase Redaction

Overview: Use ExactPhraseRedaction to replace specific text in your document.

// This replaces all instances of "John Doe" with "[personal]".
redactor.Apply(new ExactPhraseRedaction("John Doe", new ReplacementOptions("[personal]"));

Saving the Redacted Document

Overview: Preserve the document’s original format while applying a suffix to indicate modification.

Step 3: Configure Save Options

Set up SaveOptions to keep the original file type and add a date-based suffix:

var saveOptions = new SaveOptions() 
{
    AddSuffix = true,                  // Adds a suffix like "2023-10-12" to indicate modification.
    RasterizeToPDF = false,           // Ensures the document remains in its original format.
    RedactedFileSuffix = DateTime.Now.ToShortDateString()
};

Step 4: Save and Output

Save your redacted document using these options:

var outputFile = redactor.Save(saveOptions);
Console.WriteLine($"\nSource document was redacted successfully.\nFile saved to {outputFile}.\n");

Troubleshooting Tips

  • Document Not Loading: Ensure the file path is correct and accessible.
  • Redaction Fails: Verify that your search terms are accurate and present in the document.
