Hyperlinks in Word documents are clickable links that allow readers to navigate to a website or another document. While hyperlinks can provide valuable supplemental information, sometimes they can also be distracting or unnecessarily annoying, so you may want to remove them. In this article, you will learn how to remove hyperlinks from a Word document in C# and VB.NET using Spire.Doc for .NET.
Install Spire.Doc for .NET
To begin with, you need to add the DLL files included in the Spire.Doc for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.

Remove All the Hyperlinks in a Word Document
To delete all hyperlinks in a Word document at once, you'll need to find all the hyperlinks in the document and then create a custom method FlattenHyperlinks() to flatten them. The following are the detailed steps.
- Create a Document object.
- Load a sample Word document using Document.LoadFromFile() method.
- Find all the hyperlinks in the document using custom method FindAllHyperlinks().
- Loop through the hyperlinks and flatten all of them using custom method FlattenHyperlinks().
- Save the result document using Document.SaveToFile() method.
- C#
- VB.NET
using System.Drawing;
using Spire.Doc;
using Spire.Doc.Documents;

doc.LoadFromFile("Hyperlink.docx");
//Find all hyperlinks
List<Field> hyperlinks = FindAllHyperlinks(doc);
//Flatten all hyperlinks
for (int i = hyperlinks.Count - 1; i >= 0; i--)
{
FlattenHyperlinks(hyperlinks[i]);
}
//Save the result document
doc.SaveToFile("RemoveHyperlinks.docx", FileFormat.Docx);
}
//Create a method FindAllHyperlinks() to get all the hyperlinks from the sample document

SVG (Scalable Vector Graphics) is an image file format used for rendering two-dimensional images on the web. Comparing with other image file formats, SVG has many advantages such as supporting interactivity and animation, allowing users to search, index, script, and compress/enlarge images without losing quality. Occasionally, you may need to convert PDF files to SVG file format, and this article will demonstrate how to accomplish this task using Spire.PDF for .NET.
- Convert a PDF File to SVG in C#/VB.NET

In this article, we will explain how to copy an existing chart within the same PowerPoint document or between PowerPoint documents by using Spire.Presentation. Below example called a main method public IChart CreateChart(IChart baseChart, RectangleF rectangle, int nIndex).
There are three Parameters passed in this method:
- baseChart: The source chart.
- rectangle: The area that the chart will be copied to.
- nIndex: The index of the rectangle shape. For example, -1 means append it as the last shape of the slide, 0 means append as the first shape.
Now refer to the following steps:
Copy chart within the same PowerPoint document
Step 1: Instantiate a Presentation object and load the PowerPoint document.
Presentation ppt = new Presentation();
ppt.LoadFromFile("Sample.pptx");
Step 2: Get the chart that is going to be copied.
IChart chart = ppt.Slides[0].Shapes[0] as IChart;
Step 3: Copy the chart from the first slide to the specified location of the second slide within the same document.
ppt.Slides[1].Shapes.CreateChart(chart, new RectangleF(100, 100, 500, 300), 0);
Step 4: Save the document.
ppt.SaveToFile("TestResult.pptx", FileFormat.Pptx2010);

Copy chart between PowerPoint documents
Step 1: Load the first PowerPoint document.
Presentation ppt1 = new Presentation();
ppt1.LoadFromFile("Sample.pptx");
Step 2: Get the chart that is going to be copied.
IChart chart = ppt1.Slides[0].Shapes[0] as IChart;
Step 3: Load the second PowerPoint document.
Presentation ppt2 = new Presentation();
ppt2.LoadFromFile("Dest.pptx");
Step 4: Copy chart from the first document to the specified location of the second document.
ppt2.Slides[0].Shapes.CreateChart(chart, new RectangleF(100, 100, 500, 300), -1);
Step 5: Save the second document.
ppt2.SaveToFile("TestResult2.pptx", FileFormat.Pptx2010);
