使用Net将HTML简历导出为PDF格式

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

1. 整体思路是将cshtml内容读出来，然后再转为Pdf文档
2. 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）

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 :

public async 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 = "pengyuyan@outlook.com" };     //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)); }   private string readByEngineRazor(PdfReportModel model) {     string template = System.IO.File.ReadAllText("Views/Report/PdfReport.cshtml");     string htmlResult = Engine.Razor.RunCompile(template, "PdfReport", typeof(PdfReportModel), model);     return htmlResult; }  private async Task<string> readCshtml(PdfReportModel model) {     string htmlResult = await _viewRenderService.RenderToStringAsync("Report/PdfReport", model);     return htmlResult; } 

TemplateGadgetProvider.cs :

public class TemplateGadgetProvider {     public static TemplateGadgetProvider _instance;     public static TemplateGadgetProvider Instance     {         get         {             if (_instance == null)                 _instance = new TemplateGadgetProvider();             return _instance;         }     }      public string Load(string virtualPath)     {         return File.ReadAllText(virtualPath);     } }

PdfReport.cshtml :

使用RazorEngine.NetCore需要修改下面两处地方

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

Program.cs :

builder.Services.AddTransient<ViewRenderService>(); 

以上就是使用Select.HtmlToPdf.NetCore将HTML导出为PDF的全部内容！
