使用.Net將HTML簡歷匯出為PDF格式

2024-02-06碼農

現在有許多將HTML匯出PDF的第三方包，這裏介紹使用的是 Select.HtmlToPdf.NetCore

使用Select.HtmlToPdf.NetCore

整體思路是將cshtml內容讀出來，然後再轉為Pdf文件
讀取cshtml內容有兩種方法，第一種使用第三方包 RazorEngine.NetCore ，第二種使用官方方法進行讀取。（註意兩種方法的cshtml內容略有不同）

效果圖展示

我把所有的原始碼都上傳到了我的個人Github，有需要的請自取：https://github.com/WeiMing0803/ExportPdf

首先使用 `ChatGPT` 生成個人簡歷資訊

程式碼部份

HomeController.cs :

publicasync Task<IActionResult> ToPdf(){ PdfDocument pdfDocument = new PdfDocument(); HtmlToPdf converter = new HtmlToPdf();//例項化一個html到pdf轉換器物件 converter.Options.PdfPageOrientation = PdfPageOrientation.Portrait;//設定頁面方向 converter.Options.PdfPageSize = PdfPageSize.A4;//設定頁面大小 converter.Options.MarginTop = 10;//設定頁邊距 converter.Options.MarginBottom = 10; converter.Options.MarginLeft = 10; converter.Options.MarginRight = 10; PdfReportModel model = new PdfReportModel { Name = "彭於晏", Email = "[email protected]" };//string htmlResult = readByEngineRazor(model);//第一種方法，使用RazorEngine.NetCore讀取Cshtml檔string htmlResult = await readCshtml(model);//第二種方法if (!string.IsNullOrEmpty(htmlResult)) { pdfDocument = converter.ConvertHtmlString(htmlResult); }string savePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), $@"ExportPDF\{DateTime.Now.ToString("yyyyMMdd")}"); Directory.CreateDirectory(savePath);string filename = Path.Combine(savePath, $"{DateTime.Now.ToString("yyyyMMddHHmmssffff")}.pdf"); pdfDocument.Save(filename);byte[] bytes = System.IO.File.ReadAllBytes(filename);return File(bytes, "application/pdf", Path.GetFileName(filename));}privatestringreadByEngineRazor(PdfReportModel model){string template = System.IO.File.ReadAllText("Views/Report/PdfReport.cshtml");string htmlResult = Engine.Razor.RunCompile(template, "PdfReport", typeof(PdfReportModel), model);return htmlResult;}privateasync Task<string> readCshtml(PdfReportModel model){string htmlResult = await _viewRenderService.RenderToStringAsync("Report/PdfReport", model);return htmlResult;}

TemplateGadgetProvider.cs :

public classTemplateGadgetProvider{publicstatic TemplateGadgetProvider _instance;publicstatic TemplateGadgetProvider Instance {get {if (_instance == null) _instance = new TemplateGadgetProvider();return _instance; } }publicstringLoad(string virtualPath) {return File.ReadAllText(virtualPath); }}

pdfReport.css :

PdfReport.cshtml :

使用 RazorEngine.NetCore 需要修改下面兩處地方

刪除 @model PdfReportModel
將 @Html.Raw(@ style) 修改為 @@Raw(@ style)
