将 C# XML 直接转换为 PDF 是一项复杂的挑战。我们发现，在用 C# 将 XML 转换为 PDF 时，最好先使用 XSLT 作为转换模板。然后可以通过 HTML 将 XML 呈现为 PDF(5) 使用 XSLT 转换。XSLT 文档定义了如何将给定模式中的 XML 转换为准确的 HTML 表示法，是一种成熟的标准。简而言之，XSLT 就是从 XML 到 HTML 的定制翻译器。

导航至使用 XslCompiledTransform 类请阅读微软的文章以了解更多关于XSLT转换的信息。

如何用 C# 将 XML 转换为 PDF

  1. 安装 XML 至 PDF 转换器 C# 库
  2. 使用 载荷 方法导入 XSLT 变换器模板
  3. 使用 C# 将 XML 转换为 HTML 变革 方法
  4. 使用自定义渲染选项将 HTML 文件渲染为 PDF 文件
  5. 将 PDF 文档导出到所需位置

然后可以使用 .NET PDF 生成器.您可以从此处下载文件项目 链接.
