This sample demonstrates how to use PowerPointWriter's CopySlide method and Slide Data Binding Property to copy slides and bind them with different data. This makes it easy to programmatically create multiple slides with the same layout in your presentation.
...
The code below uses PowerPointApplication to copy the slide in our template, then passes the presentation to PowerPointTemplate to bind the data.

public void CopySlide(){
PowerPointApplication ppta = new PowerPointApplication();
Presentation pres = ppta.Open("template.pptx");
//Create a copy of the slide and add it to the end of the presentation
Slide slideToCopy = pres.Slides[0];
pres.Slides.CopySlide(slideToCopy, (pres.Slides.Count));
//pass the presentation to PowerPointTemplate
PowerPointTemplate pptt = new PowerPointTemplate();
pptt.Open(ppta, pres);
//Set the column names - will be the same for both slides
string[] titleCol = {"Title"};
string[] detailsCol = {"Details"};
//Create a Data Binding Property
DataBindingProperties dataProps = pptt.CreateDataBindingProperties();
//Get the data for the first slide - Team Members
//Data for the TrainingItem data source
object[] titleArray = {"Team Members"};
DataTable dtTeam = GetCSVData("Team.csv");
//Set Slide to be the first slide in our presentation
dataProps.Slide = 0;
//Bind the Data
pptt.BindData(titleArray, titleCol, "Training", dataProps );
pptt.BindData(dtTeam, "TrainingItems", dataProps);
//Get the data for the second slide - Agile Development
object[] titleArray2 = { "Agile Development / Scrum" };
DataTable dtAgile = GetCSVData("Agile.csv");
//Change our Data Binding Properties to scope to the second slide
dataProps.Slide = 1;
//Bind the Data - only the array of values changed
pptt.BindData(titleArray2, titleCol, "Training", dataProps);
pptt.BindData(dtAgile, "TrainingItems", dataProps);
//Process the data
pptt.Process();
pptt.Save("output.pptx");
