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:github.com/WeiMing0803…
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.css :

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)

ViewRenderService :
public class ViewRenderService{ private readonly IRazorViewEngine _razorViewEngine; private readonly ITempDataProvider _tempDataProvider; private readonly IServiceProvider _serviceProvider; public ViewRenderService(IRazorViewEngine razorViewEngine,ITempDataProvider tempDataProvider,IServiceProvider serviceProvider) {_razorViewEngine = razorViewEngine;_tempDataProvider = tempDataProvider;_serviceProvider = serviceProvider; } public async Task<string> RenderToStringAsync(string viewName, object model) {var httpContext = new DefaultHttpContext { RequestServices = _serviceProvider };var actionContext = new ActionContext(httpContext, new RouteData(), new ActionDescriptor());using (var sw = new StringWriter()){ var viewResult = _razorViewEngine.FindView(actionContext, viewName, false); if (viewResult.View == null) {throw new ArgumentNullException($"{viewName} does not match any available view"); } var viewDictionary = new ViewDataDictionary(new EmptyModelMetadataProvider(), new ModelStateDictionary()) {Model = model }; var viewContext = new ViewContext(actionContext,viewResult.View,viewDictionary,new TempDataDictionary(actionContext.HttpContext, _tempDataProvider),sw,new HtmlHelperOptions() ); await viewResult.View.RenderAsync(viewContext); return sw.ToString();} }}
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!
