XtraReports > 示例 > 如何： 把报表导出为 PDF

下面的示例演示了如何把报表导出为 PDF 格式。 要完成此任务，需使用 XtraReport.ExportToPdf 方法。 此示例也演示了当报表被导出为 PDF 时，哪些特定的 PdfExportOptions 可能被使用。

为了使此示例工作，首先需要 添加新报表 (命名为 XtraReport1) 到项目中，拖放一些报表控件到报表中，然后执行下面的代码 (例如，在窗体上任一按钮的 Button.Click 事件处理程序中)。 也要注意，如果想让结果文件自动被系统中默认的用于打开 *.pdf 文件的程序打开，那么可以调用在本例中也展示了的 StartProcess 方法。
