Step 1: Create a new project

Start by creating a new C# Console Application project.

Step 2: Install the NuGet package

Add the Syncfusion.Presentation.Net.Core package to your project from NuGet.org.

Step 3: Add required namespaces to create PowerPoint presentation

Add the following namespaces to your Program.cs file:

c#
using Syncfusion.Presentation;
using System;

Step 4: Create a PowerPoint presentation

Create a new PowerPoint presentation and add a slide with background formatting.

Run

c#
//Create a new instance of PowerPoint Presentation file
IPresentation pptxDoc = Presentation.Create();
//Add a new slide to file and apply background color
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.TitleOnly);
//Specify the fill type and fill color for the slide background 
slide.Background.Fill.FillType = FillType.Solid;
slide.Background.Fill.SolidFill.Color = ColorObject.FromArgb(232, 241, 229);

Step 5: Add title and description

Add a title to the slide and inserts descriptive text using a text box.

c#
//Add title content to the slide by accessing the title placeholder of the TitleOnly layout-slide
IShape titleShape = slide.Shapes[0] as IShape;
titleShape.TextBody.AddParagraph("Company History").HorizontalAlignment = HorizontalAlignmentType.Center;
//Add description content to the slide by adding a new TextBox
IShape descriptionShape = slide.AddTextBox(53.22, 141.73, 874.19, 77.70);
descriptionShape.TextBody.Text = "IMN Solutions PVT LTD is a software company, established in 1987, by George Milton. The company has been listed as the trusted partner for many high-profile organizations since 1988 and has received awards for quality products from reputed organizations.";

Step 6: Add bullet points

Add formatted bullet points to the slide with proper indentation and styling.

c#
//Add bullet points to the slide
IShape bulletPointsShape = slide.AddTextBox(53.22, 270, 437.90, 116.32);
//Add a paragraph for a bullet point
IParagraph firstPara = bulletPointsShape.TextBody.AddParagraph("The company acquired the MCY corporation for 20 billion dollars and became the top revenue maker for the year 2015.");
//Format how the bullets should be displayed
firstPara.ListFormat.Type = ListType.Bulleted;
firstPara.LeftIndent = 35;
firstPara.FirstLineIndent = -35;
// Add another paragraph for the next bullet point
IParagraph secondPara = bulletPointsShape.TextBody.AddParagraph("The company is participating in top open source projects in automation industry.");
//Format how the bullets should be displayed
secondPara.ListFormat.Type = ListType.Bulleted;
secondPara.LeftIndent = 35;
secondPara.FirstLineIndent = -35;

Step 7: Add an image

Insert an image to the slide with specified size and position.

c#
//Get a picture as stream
FileStream pictureStream = new FileStream(Path.GetFullPath(@"Data/Image.jpg"), FileMode.Open);
//Add the picture to a slide by specifying its size and position
slide.Shapes.AddPicture(pictureStream, 499.79, 238.59, 364.54, 192.16);

Step 8: Add a shape

Add an auto-shape to the slide and applies formatting with text content.

c#
//Add an auto-shape to the slide
IShape stampShape = slide.Shapes.AddShape(AutoShapeType.Explosion1, 48.93, 430.71, 104.13, 80.54);
//Format the auto-shape color by setting the fill type and text
stampShape.Fill.FillType = FillType.None;
stampShape.TextBody.AddParagraph("IMN").HorizontalAlignment = HorizontalAlignmentType.Center;

Step 9: Save the PowerPoint presentation

Save the created PowerPoint presentation to a file stream.

c#
//Save the PowerPoint Presentation as stream
FileStream outputStream = new FileStream(Path.GetFullPath(@"Output/Sample.pptx"), FileMode.Create);
pptxDoc.Save(outputStream);
outputStream.Close();
