How to Remove Text Signatures from Your Documents with GroupDocs.Signature

Why Would You Need to Delete Text Signatures?

Have you ever needed to remove a text signature from a document programmatically? Perhaps you’re building a document management system where signatures need to be updated regularly, or maybe you’re developing an application that handles document revisions. Whatever your scenario, GroupDocs.Signature for .NET makes this process remarkably simple.

This powerful library gives you everything you need to handle electronic signatures in your .NET applications. Whether you’re working on contract management, approval workflows, or any other document-centric application, you’ll find that removing text signatures becomes a straightforward task.

What You’ll Need Before Starting

Before we dive into the code and show you how to delete text signatures, let’s make sure you have everything set up correctly:

1. Your Development Environment

First, you’ll need a working .NET development environment on your computer. If you haven’t set this up yet, you can download the .NET SDK directly from Microsoft’s website.

2. The GroupDocs.Signature Library

Next, you’ll need to download and install the GroupDocs.Signature for .NET library. You can get it here: Download GroupDocs.Signature for .NET

3. A Test Document

Finally, prepare a sample document that contains text signatures. This could be a Word document, PDF, or any other supported format that you’d like to work with.

Setting Up Your Project

Now that you have everything in place, let’s start by importing the necessary namespaces into your project:

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

These namespaces give you access to all the functionality you’ll need to delete text signatures from your documents.

How to Delete a Text Signature: A Step-by-Step Guide

Let’s break down the process of removing a text signature into easy-to-follow steps:

Step 1: Where Are Your Files?

First, we need to define where your document is located and where you want to save the result:

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

Step 2: Make a Copy of Your Document

Since the Delete method works directly on the document, we’ll create a copy first to preserve your original:

File.Copy(filePath, outputFilePath, true);

Step 3: Create a Signature Object

Now, let’s initialize a Signature object using the path to our copy:

using (Signature signature = new Signature(outputFilePath))
{
    // We'll add our deletion code here shortly
}

Step 4: Find the Text Signatures in Your Document

Before we can delete a signature, we need to find it. Here’s how we search for text signatures:

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

Step 5: Remove the Text Signature

Now comes the fun part! If we find any text signatures, we’ll delete the first one:

if (signatures.Count > 0)
{
    TextSignature textSignature = signatures[0];
    bool result = signature.Delete(textSignature);
    if (result)
    {
        Console.WriteLine($"Great news! The signature with text '{textSignature.Text}' was successfully deleted from '{fileName}'.");
    }
    else
    {
        Console.WriteLine($"Hmm, something went wrong. We couldn't find a signature with text '{textSignature.Text}' to delete.");
    }
}

And that’s it! With these five simple steps, you’ve successfully removed a text signature from your document.
