3. Document for Testing

Prepare a sample document (e.g., a Word document, PDF, etc.) that you’ll use to test the signature deletion functionality.

Import Namespaces

To begin using GroupDocs.Signature for .NET in your project, import the necessary namespaces:

using System;
using System.Collections.Generic;
using System.IO;
using GroupDocs.Signature;
using GroupDocs.Signature.Domain;
using GroupDocs.Signature.Options;

Now, let’s break down the process of deleting a text signature from a document into multiple steps:

Step 1: Define File Paths

First, define the paths for your input document, output document, and file name.

string filePath = "sample_multiple_signatures.docx";
string fileName = Path.GetFileName(filePath);
string outputFilePath = Path.Combine("Your Document Directory", "DeleteText", fileName);

Step 2: Copy Source File

Since the Delete method works with the same document, copy the source file to a new location.

File.Copy(filePath, outputFilePath, true);

Step 3: Initialize Signature Object

Initialize a Signature object using the output file path.

using (Signature signature = new Signature(outputFilePath))
{
    // Code for deleting text signature will go here
}

Step 4: Search for Text Signatures

Search for text signatures within the document using TextSearchOptions.

TextSearchOptions options = new TextSearchOptions();
List<TextSignature> signatures = signature.Search<TextSignature>(options);

Step 5: Delete Text Signature

If text signatures are found, delete the first one.

if (signatures.Count > 0)
{
    TextSignature textSignature = signatures[0];
    bool result = signature.Delete(textSignature);
    if (result)
    {
        Console.WriteLine($"Signature with Text '{textSignature.Text}' was deleted from document ['{fileName}'].");
    }
    else
    {
        Helper.WriteError($"Signature was not deleted from the document! Signature with Text '{textSignature.Text}' was not found!");
    }
}

Conclusion

In conclusion, GroupDocs.Signature for .NET offers a straightforward approach to deleting text signatures from documents programmatically. By following the steps outlined in this tutorial, developers can seamlessly integrate signature deletion functionality into their .NET applications, enhancing document management processes and ensuring compliance with electronic signature standards.
