在 C# 和 VB.NET 中将 XML 转换为 PDF
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
- 安装 XML 至 PDF 转换器 C# 库
- 使用
载荷
方法导入 XSLT 变换器模板 - 使用 C# 将 XML 转换为 HTML
变革
方法 - 使用自定义渲染选项将 HTML 文件渲染为 PDF 文件
- 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.
