Create and write PowerPoint files in C# and VB.NET

With GemBox.Presentation you can create and write PowerPoint files in an easy and straightforward manner. This is done by composing presentation elements through factory methods.

You can save the presentation using one of the PresentationDocument.Savemethods from your C# and VB.NET application. These methods enable you to work with a physical file (when providing the file's path) or with an in-memory file (when providing the file's Stream).

The following example shows how you can create a new PowerPoint file and write some shape and text to the presentation.

        ComponentInfo.SetLicense("FREE-LIMITED-KEY");

        var presentation = new PresentationDocument();

        var slide = presentation.Slides.AddNew(SlideLayoutType.Custom);

        var shape = slide.Content.AddShape(ShapeGeometryType.RoundedRectangle, 2, 2, 8, 4, LengthUnit.Centimeter);
        shape.Format.Fill.SetSolid(Color.FromName(ColorName.DarkBlue));

        var run = shape.Text.AddParagraph().AddRun("This sample shows how to write or save a new PowerPoint file with GemBox.Presentation.");
        run.Format.Fill.SetSolid(Color.FromName(ColorName.White));

        presentation.Save("Writing.%OutputFileType%");
    }
}
