该文将介绍如何使用Spire.Presentation for .NET将OpenDocument 演示文稿（.odp）另存为PDF格式。

using Spire.Presentation;

namespace odptoPDF
{
    class Program
    {
        static void Main(string[] args)
        {
            //加载示例文档
            Presentation presentation = new Presentation();
            presentation.LoadFromFile("Sample.odp",FileFormat.ODP);

            presentation.SaveToFile("OdptoPDF.pdf",FileFormat.PDF);

        }
    }
}

Imports Spire.Presentation

Namespace odptoPDF
    
    Class Program
        
        Private Shared Sub Main(ByVal args() As String)
            '加载示例文档
            Dim presentation As Presentation = New Presentation
            presentation.LoadFromFile("Sample.odp", FileFormat.ODP)
            presentation.SaveToFile("OdptoPDF.pdf", FileFormat.PDF)
        End Sub
    End Class
End Namespace
