Step 6: Add a new button in the Index.cshtml as shown below.

@{
    Html.BeginForm("OpenAndSavePresentation", "Home", FormMethod.Get);
    {
    <div>
        <br />
        <input type="submit" value="Open and Save Presentation" style="width:150px;height:27px" />
    </div>
    }
    Html.EndForm();
}

Step 7: Add a new action method OpenAndSavePresentation in HomeController.cs and include the below code snippet to open an existing Presentation in ASP.NET MVC.

FileStream fileStreamPath = new FileStream(Server.MapPath("~/App_Start/Template.pptx"), FileMode.Open, FileAccess.Read);
//Open an existing PowerPoint presentation.
IPresentation pptxDoc = Presentation.Open(fileStreamPath)

Step 8: Add below code snippet demonstrates accessing a shape from a slide and changing the text within it.

//Gets the first slide from the PowerPoint presentation
ISlide slide = pptxDoc.Slides[0];
//Gets the first shape of the slide
IShape shape = slide.Shapes[0] as IShape;
//Change the text of the shape
if (shape.TextBody.Text == "Company History")
    shape.TextBody.Text = "Company Profile";

Step 9: Add below code example to save the PowerPoint Presentation in ASP.NET MVC.

//Save the PowerPoint Presentation as stream
MemoryStream pptxStream = new MemoryStream();
pptxDoc.Save(pptxStream);
pptxStream.Position = 0;
//Download Powerpoint document in the browser.
return File(pptxStream, "application/powerpoint", "Result.pptx");
