Section

Examples for managing presentation sections—add, access, remove, and rename them programmatically using Aspose.Slides for .NET.

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.

Each printed CaseNN.cs file is compiled verbatim with the included Program.cs and bootstrap. Checks run before saving and after reopening the result.

Add a Section

Create a section that starts at a specific slide.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;

internal static partial class Program
{
    static void Case01()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        // Specify the slide that marks the beginning of the section.
        presentation.Sections.AddSection("New Section", slide);

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-001", p =>
        {
            Context.Require(p.Sections.Count == 1 && p.Sections[0].Name == "New Section", "AddSection: semantic check 1 failed.");
        });
        Context.Pass("elements/section/block-001", "AddSection", "save-reopen-structure");
    }
}

Access a Section

Read section information from a presentation.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;

internal static partial class Program
{
    static void Case02()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        presentation.Sections.AddSection("My Section", slide);

        // Access a section by index.
        var section = presentation.Sections[0];
        var sectionName = section.Name;

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-002", p =>
        {
            Context.Require(p.Sections.Count == 1 && p.Sections[0].Name == "My Section", "AccessSection: semantic check 1 failed.");
        });
        Context.Pass("elements/section/block-002", "AccessSection", "save-reopen-structure");
    }
}

Remove a Section

Delete a previously added section.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;

internal static partial class Program
{
    static void Case03()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        var section = presentation.Sections.AddSection("Temporary Section", slide);

        // Remove the first section.
        presentation.Sections.RemoveSection(section);

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-003", p =>
        {
            Context.Require(p.Sections.Count == 0, "RemoveSection: semantic check 1 failed.");
        });
        Context.Pass("elements/section/block-003", "RemoveSection", "save-reopen-structure");
    }
}

Rename a Section

Change the name of an existing section.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;

internal static partial class Program
{
    static void Case04()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        presentation.Sections.AddSection("Old Name", slide);

        var section = presentation.Sections[0];
        section.Name = "New Name";

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-004", p =>
        {
            Context.Require(p.Sections[0].Name == "New Name", "RenameSection: semantic check 1 failed.");
        });
        Context.Pass("elements/section/block-004", "RenameSection", "save-reopen-structure");
    }
}
