如何使用IronPDF构建一个ASP.NET Core PDF查看器

using IronPdf;

var renderer = new ChromePdfRenderer();

renderer.RenderingOptions.MarginTop = 20;

renderer.RenderingOptions.MarginBottom = 20;

renderer.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.A4;

string html = $@"
    <h1>Loan Application Summary</h1>
    <p><strong>Applicant:</strong> {submission.FullName}</p>
    <p><strong>Submitted:</strong> {submission.SubmittedAt:f}</p>
    <p><strong>Loan Amount:</strong> {submission.LoanAmount:C}</p>
    <p><strong>Reference:</strong> {submission.ReferenceNumber}</p>
    <hr/>
    <h2>Employment Details</h2>
    <p>{submission.EmployerName} — {submission.AnnualIncome:C} per year</p>";

PdfDocument summary = renderer.RenderHtmlAsPdf(html);

Imports IronPdf

Dim renderer As New ChromePdfRenderer()

renderer.RenderingOptions.MarginTop = 20

renderer.RenderingOptions.MarginBottom = 20

renderer.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.A4

Dim html As String = $"

Dim summary As PdfDocument = renderer.RenderHtmlAsPdf(html)
