This article demonstrates embedding a file as an OLE object and updating its data using **Aspose.Slides for .NET**.

## **Add an OLE Object**

Embed a PDF file into the presentation.

```csharp
using Aspose.Slides;
using Aspose.Slides.DOM.Ole;

static void AddOleObject()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var pdfData = File.ReadAllBytes("doc.pdf");
    var dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
    var oleFrame = slide.Shapes.AddOleObjectFrame(20, 20, 50, 50, dataInfo);
}
```

## **Access an OLE Object**

Retrieve the first OLE object frame on a slide.

```csharp
using Aspose.Slides;
using Aspose.Slides.DOM.Ole;

static void AccessOleObject()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var pdfData = File.ReadAllBytes("doc.pdf");
    var dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
    var oleFrame = slide.Shapes.AddOleObjectFrame(20, 20, 50, 50, dataInfo);

    var firstOleFrame = slide.Shapes.OfType<IOleObjectFrame>().First();
}
```

## **Remove an OLE Object**

Delete an embedded OLE object from the slide.

```csharp
using Aspose.Slides;
using Aspose.Slides.DOM.Ole;

static void RemoveOleObject()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var pdfData = File.ReadAllBytes("doc.pdf");
    var dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
    var oleFrame = slide.Shapes.AddOleObjectFrame(20, 20, 50, 50, dataInfo);

    slide.Shapes.Remove(oleFrame);
}
```

## **Update OLE Object Data**

Replace the data embedded in an existing OLE object.

```csharp
using Aspose.Slides;
using Aspose.Slides.DOM.Ole;

static void UpdateOleObjectData()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var pdfData = File.ReadAllBytes("doc.pdf");
    var dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
    var oleFrame = slide.Shapes.AddOleObjectFrame(20, 20, 50, 50, dataInfo);

    var newData = File.ReadAllBytes("Picture.png");
    var newDataInfo = new OleEmbeddedDataInfo(newData, "png");
    oleFrame.SetEmbeddedData(newDataInfo);
}
```
