Syncfusion® PowerPoint is a .NET PowerPoint library used to create, read, edit and convert PowerPoint documents programmatically without Microsoft PowerPoint or interop dependencies. Using this library, you can open and save a Presentation in WPF.

Steps to open and save PowerPoint Presentation programmatically

Step 1: Create a new C# WPF application project.

Step 2: Install the Syncfusion.Presentation.Wpf NuGet package as reference to your .NET Standard applications from NuGet.org.

NOTE

Starting with v16.2.0.x, if you reference Syncfusion® assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion® license key in your application to use our components.

Step 3: Add a new button in the MainWindow.xaml as shown below.

C#

<Window x:Class="Read_and_edit_PowerPoint_presentation.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:Read_and_edit_PowerPoint_presentation"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Button x:Name="button" Content="Open and Save Presentation" Click="OpenAndSavePresentation" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    </Grid>
</Window>

Step 4: Include the following namespaces in the MainWindow.xaml.cs file.

C#

using Syncfusion.Presentation;

Step 5: Add the following code in OpenAndSavePresentation to open an existing PowerPoint Presentation in WPF.

C#

//Opens an existing PowerPoint presentation.
IPresentation pptxDoc = Presentation.Open("Data/Template.pptx");

Step 6: Add below code snippet demonstrates accessing a shape from a slide and changing the text within it.

C#

//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 7: Add below code example to save the PowerPoint Presentation in WPF.

C#

//Saves the Presentation to the file system.
pptxDoc.Save("Result.pptx");
//Close the PowerPoint presentation
pptxDoc.Close();
