转换的时候老是出现dos窗口,这个怎么隐藏掉啊?
application = new PowerPoint.ApplicationClass();
persentation = application.Presentations.Open(sourcePath, Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoFalse);
persentation.SaveAs(targetPath, targetFileType,Microsoft.Office.Core.MsoTriState.msoTrue);
