How to create a ASP.NET WebForms PowerPoint file in C#?
The following steps demonstrate how to create a simple PowerPoint presentation in a Windows forms application using Presentation library.
Step 1: Create a new Windows Forms application. Name it as GettingStarted.
Step 2: Install Presentation assemblies with NuGet
In Visual Studio, select Tools > NuGet Package Manager > Package Manager Console and execute the below command for the project.
Step 3: Add a new button in the form editor.
Step 4: Include the below code snippet in the click event of the button in Form.cs, to create a PowerPoint presentation and save it as a file.
//Creates a new instance of PowerPoint Presentation IPresentation presentation = Presentation.Create(); //Adds a slide to the PowerPoint Presentation ISlide firstSlide = presentation.Slides.Add(SlideLayoutType.Blank); //Adds a textbox in a slide by specifying its position and size IShape textShape = firstSlide.AddTextBox(100, 75, 756, 200); //Adds a paragraph into the textShape IParagraph paragraph = textShape.TextBody.AddParagraph(); //Set the horizontal alignment of paragraph paragraph.HorizontalAlignment = HorizontalAlignmentType.Center; //Adds a textPart in the paragraph ITextPart textPart = paragraph.AddTextPart("Hello Presentation"); //Applies font formatting to the text textPart.Font.FontSize = 80; textPart.Font.Bold = true; //Adds a new paragraph with text. paragraph = textShape.TextBody.AddParagraph("Adventure Works Cycles, the fictitious company on which the AdventureWorks sample databases are based, is a large, multinational manufacturing company. The company manufactures and sells metal and composite bicycles to North American, European and Asian commercial markets"); //Sets the list type as bullet paragraph.ListFormat.Type = ListType.Bulleted; //Sets the bullet character for this list paragraph.ListFormat.BulletCharacter = Convert.ToChar(183); //Sets the font of the bullet character paragraph.ListFormat.FontName = "Symbol"; //Sets the hanging value as 20 paragraph.FirstLineIndent = -20; //Adds a new paragraph paragraph = textShape.TextBody.AddParagraph("In 2000, Adventure Works Cycles bought a small manufacturing plant, Importadores Neptuno, located in Mexico."); //Sets the list type as bullet paragraph.ListFormat.Type = ListType.Bulleted; //Sets the list level as 2. Possible values can range from 0 to 8 paragraph.IndentLevelNumber = 2; //Gets the image from file path Image image = Image.FromFile(@"image.jpg"); // Adds the image to the slide by specifying position and size firstSlide.Pictures.AddPicture(new MemoryStream(image.ImageData), 300, 270, 410, 250); //Saves the Presentation in the given name presentation.Save("Output.pptx"); //Releases the resources occupied presentation.Close();
Step 5: Compile & execute the application. Now this application creates a simple PowerPoint presentation.
