C# API 将 XPS 转换为 PDF
要有效地进行 XPS 到 PDF 转换为 C#,我们将使用 Aspose.Page 为 .NET 这个坚实的图书馆允许开发人员创建、编辑、操纵和转换XPS和 EPS / PS Aspose.Page for .NET 是一个可靠、独立的 API,无缝地集成到您的 .net 应用程序中。
你也可以 下载DLL 直接或使用下列 API 安装 诺基亚 命令:
PM> Install-Package Aspose.Page
将 XPS 转换为 PDF 使用 C#
要将整个 XPS 文档转换为 PDF 格式,请遵循以下步骤:
- 输入 XPS 文件。
- 以所需的参数启动选项对象。
- 创建一个例子的 PdfDevice 播放。
- 将 XPS 文件导出到 PDF 文件中。
下面是一个代码样本显示 如何将XPS文件转换为PDF使用C#:

将 XPS 的特定页面转换为 PDF 以 C#
如果您需要将特定页面从 XPS 文档转换为 PDF 格式,请遵循以下步骤:
- 启动 XPS 输入流。
- 将 XPS 文件从流中加载。
- 创建 PdfSaveOptions 对象的例子。
- 指定转换页面号码。
- 将文件保存为 PDF 文件。

OXPS 到 PDF 转换器在 C#
OXPS 格式是 XPS 文件格式的先进版本,但它可能不受旧操作系统的支持。
- 启动 OXPS 输入流。
- 从流中下载 OXPS 文件。
- 创建 PdfSaveOptions 类的例子。
- 将 OXPS 文件导出到 PDF 文件中。
