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 Windows Forms.

Steps to open and save PowerPoint Presentation programmatically

Step 1: Create a new C# Windows Forms application project.

Step 2: Install the Syncfusion.Presentation.WinForms 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: Include the following namespaces in the Form1.Designer.cs file.

C#

using Syncfusion.Presentation;

Step 4: Add a new button in Form1.Designer.cs file.

C#

private Button btnCreate;
private Label label;
private void InitializeComponent()
{
    System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(Form1));
    this.label = new System.Windows.Forms.Label();
    this.btnCreate = new System.Windows.Forms.Button();
    this.SuspendLayout();
    // 
    // label
    // 
    this.label.Location = new System.Drawing.Point(12, 19);
    this.label.Name = "label";
    this.label.Size = new System.Drawing.Size(426, 88);
    this.label.TabIndex = 0;
    this.label.Text = resources.GetString("label.Text");
    this.label.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
    // 
    // btnCreate
    // 
    this.btnCreate.Location = new System.Drawing.Point(180, 110);
    this.btnCreate.Name = "btnCreate";
    this.btnCreate.Size = new System.Drawing.Size(85, 36);
    this.btnCreate.TabIndex = 1;
    this.btnCreate.Text = "Open and Save Presentation";
    this.btnCreate.Click += new System.EventHandler(this.btnOpenAndSave_Click);
    // 
    // Form1
    // 
    this.ClientSize = new System.Drawing.Size(450, 150);
    this.Controls.Add(this.label);
    this.Controls.Add(this.btnCreate);
    this.Name = "Form1";
    this.Text = "Open and Save Presentation";
    this.ResumeLayout(false);
}

Step 5: Add the following code in btnOpenAndSave_Click to open an existing PowerPoint Presentation in Windows Forms.

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 Windows Forms.

C#

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