使用.Net将HTML简历导出为PDF格式

2024-02-06码农

现在有许多将HTML导出PDF的第三方包，这里介绍使用的是 Select.HtmlToPdf.NetCore

使用Select.HtmlToPdf.NetCore

整体思路是将cshtml内容读出来，然后再转为Pdf文档
读取cshtml内容有两种方法，第一种使用第三方包 RazorEngine.NetCore ，第二种使用官方方法进行读取。（注意两种方法的cshtml内容略有不同）

效果图展示

我把所有的源代码都上传到了我的个人Github，有需要的请自取：https://github.com/WeiMing0803/ExportPdf

首先使用 `ChatGPT` 生成个人简历信息

代码部分

HomeController.cs :

publicasync Task<IActionResult> ToPdf(){ PdfDocument pdfDocument = new PdfDocument(); HtmlToPdf converter = new HtmlToPdf();//实例化一个html到pdf转换器对象 converter.Options.PdfPageOrientation = PdfPageOrientation.Portrait;//设置页面方向 converter.Options.PdfPageSize = PdfPageSize.A4;//设置页面大小 converter.Options.MarginTop = 10;//设置页边距 converter.Options.MarginBottom = 10; converter.Options.MarginLeft = 10; converter.Options.MarginRight = 10; PdfReportModel model = new PdfReportModel { Name = "彭于晏", Email = "[email protected]" };//string htmlResult = readByEngineRazor(model);//第一种方法，使用RazorEngine.NetCore读取Cshtml文件string htmlResult = await readCshtml(model);//第二种方法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.cshtml :

使用 RazorEngine.NetCore 需要修改下面两处地方

删除 @model PdfReportModel
将 @Html.Raw(@ style) 修改为 @@Raw(@ style)
