Razor 到 PDF（Blazor Server）

此示例演示了如何将Razor组件转换为PDF文档。

IronPdf.Extensions.Blazor 包是主要 IronPDF 包的扩展。为了将 Razor 组件的内容页转换为 PDF，需要同时使用 IronPdf.Extensions.Blazor 和主要的 IronPdf 包。

在下面的代码示例中，已经创建了一个名为 PersonInfo 的模型。在 OnInitializedAsync 方法中，我们插入了多个新的 PersonInfo 对象到 persons List 中。然后我们将 persons List 与 Parameters 字典中的字符串 "persons" 关联起来。

在 PrintToPdf 方法中，我们实例化了 ChromePdfRenderer 类。要将 Razor 组件转换为 PDF 文档，我们使用 RenderRazorComponentToPdf 方法。在代码示例中，我们将 Parameters 字典传递给方法以进行渲染。
