SmartArt
This article demonstrates how to add SmartArt graphics, access them, remove them, and change layouts using Aspose.Slides for .NET.
Copy a C# block into Program.cs in a .NET project with Aspose.Slides.NET6.CrossPlatform installed. Each block is a complete program. Run one block at a time. The ZIP contains the IDE-ready project and its verification checks. The copied code runs in evaluation mode. For licensed output, apply your license before creating a presentation, as described in the licensing guide.
Download and run
Download the complete project, extract it, and open Example.sln or run:
dotnet restore Example.sln
dotnet run --project Example.csproj -- --mode evaluation
The download includes every case below, its fixture helpers and inputs. Program.cs runs all cases; use --action block-001 to run one independently. Outputs and an action report are written to the printed output directory. No previous example or working-directory setup is required. Evaluation adds a watermark and can truncate read-back text; the short fixtures still have explicit structural checks. For full text and no watermark, use --mode licensed --license PATH with your own valid license. See the setup guide for supported SDKs and native prerequisites.
Add SmartArt
Insert a SmartArt graphic using one of the built-in layouts.
using Aspose.Slides.Export;
using Aspose.Slides;
using Aspose.Slides.SmartArt;
using var presentation = new Presentation();
var slide = presentation.Slides[0];
slide.Shapes.AddSmartArt(50, 50, 400, 300, SmartArtLayoutType.BasicProcess);
presentation.Save("smart-art-01.pptx", SaveFormat.Pptx);
Access SmartArt
Retrieve the first SmartArt object on the slide and report its node count.
using System;
using Aspose.Slides.Export;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.SmartArt;
using var presentation = new Presentation();
var slide = presentation.Slides[0];
slide.Shapes.AddSmartArt(50, 50, 400, 300, SmartArtLayoutType.BasicProcess);
var firstSmartArt = slide.Shapes.OfType<ISmartArt>().First();
Console.WriteLine($"Node count: {firstSmartArt.AllNodes.Count}");
presentation.Save("smart-art-02.pptx", SaveFormat.Pptx);
Remove SmartArt
Delete a SmartArt shape from the slide.
using Aspose.Slides.Export;
using Aspose.Slides;
using Aspose.Slides.SmartArt;
using var presentation = new Presentation();
var slide = presentation.Slides[0];
var smartArt = slide.Shapes.AddSmartArt(50, 50, 400, 300, SmartArtLayoutType.BasicProcess);
slide.Shapes.Remove(smartArt);
presentation.Save("smart-art-03.pptx", SaveFormat.Pptx);
Change SmartArt Layout
Update the layout type of an existing SmartArt graphic.
using Aspose.Slides.Export;
using Aspose.Slides;
using Aspose.Slides.SmartArt;
using var presentation = new Presentation();
var slide = presentation.Slides[0];
var smartArt = slide.Shapes.AddSmartArt(50, 50, 400, 300, SmartArtLayoutType.BasicBlockList);
smartArt.Layout = SmartArtLayoutType.VerticalPictureList;
presentation.Save("smart-art-04.pptx", SaveFormat.Pptx);
