Prerequisites

Before we begin, ensure you have the following prerequisites in place:

  • Basic knowledge of C# programming language.
  • GroupDocs.Signature for .NET installed in your development environment. You can download it from here.
  • An Integrated Development Environment (IDE) such as Visual Studio installed on your system.
  • Sample document(s) containing signatures for demonstration purposes.

Import Namespaces

To start with, make sure to import the necessary namespaces into your project. This allows you to access the functionalities provided by GroupDocs.Signature for .NET effortlessly.

using System;
using System.IO;
using GroupDocs.Signature;
using GroupDocs.Signature.Domain;

Step 1: Define File Paths

Begin by defining the paths for your input document and the output directory where the modified document will be saved.

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

Ensure to replace "Your Document Directory" with the actual directory path where your documents are stored.

Step 2: Copy the Source File

Since the Delete method works with the same document, it’s recommended to make a copy of the source file to preserve the original.

File.Copy(filePath, outputFilePath, true);

This step ensures that any modifications made to the document do not affect the original file.

Step 3: Delete Signatures

Now, initialize a Signature object with the output file path and proceed to delete signatures by type.

using (Signature signature = new Signature(outputFilePath))
{
    DeleteResult result = signature.Delete(SignatureType.QrCode);

Here, we’re deleting QR-Code signatures from the document. You can replace SignatureType.QrCode with the desired signature type according to your requirements.

Step 4: Process Deletion Result

After deletion, check the result to determine the success of the operation and display relevant information.

if (result.Succeeded.Count > 0)
{
    Console.WriteLine("Following QR-Code signatures were deleted:");
    int number = 1;
    foreach (QrCodeSignature temp in result.Succeeded)
    {
        Console.WriteLine($"Signature #{number++}: Type: {temp.SignatureType} Id:{temp.SignatureId}, Text: {temp.Text}");
    }
}
else
{
    Helper.WriteError("No QR-Code signature was deleted.");
}

This step ensures transparency by providing feedback on the deleted signatures.

Conclusion

In conclusion, managing signatures within your documents is simplified with GroupDocs.Signature for .NET. By following the steps outlined in this tutorial, you can effortlessly delete signatures by type, enhancing the efficiency of your document management workflows.
