Split PowerPoint file into two files in C#

This is an C# example of splitting a PowerPoint file into multiple ones by number of pages. 

String inputFilePath = Program.RootPath + "\\" + "1.pptx";
String outputFilePath1 = Program.RootPath + "\\" + "Split1.pptx";
String outputFilePath2 = Program.RootPath + "\\" + "Split2.pptx";
String[] outputOps = new  String[] { outputFilePath1, outputFilePath2 };
//  split a PowerPoint file with options
PPTXDocument.SplitDocument(inputFilePath, 2, outputOps);


Split PowerPoint Document into Multiple PowerPoint Files in C#

You can use the following C# demo to split PowerPoint document to four files. 

String inputFilePath = Program.RootPath + "\\" + "1.pptx";
String outputFileName = "Output.pptx";
int[] splitIndex = new int[3] { 1, 3, 5 }; // Valid value for each index: 1 to (Page Count - 1).

// Create output PowerPoint file path list
List<String> outputFilePaths = new List<String>();
for (int i = 0; i <= splitIndex.Length; i++)
{
        outputFilePaths.Add(Program.RootPath + "\\" + outputFileName + "_" + i.ToString() + ".pptx");
}

// Split input PowerPoint file to 4 files:
// File 0: page 0.
// File 1: page 1 ~ 2.
// File 2: page 3 ~ 4.
// File 3: page 5 ~ the last page.
PPTXDocument.SplitDocument(inputFilePath, splitIndex, outputFilePaths.ToArray());
