正文

現在有許多將HTML導出PDF的第三方包，這里介紹使用的是Select.HtmlToPdf.NetCore

使用Select.HtmlToPdf.NetCore

• 整體思路是將cshtml內容讀出來，然后再轉為Pdf文檔
• 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。（注意兩種方法的cshtml內容略有不同）

效果圖展示

我把所有的源代碼都上傳到了我的個人Github，有需要的請自取：github.com/WeiMing0803…

首先使用ChatGPT生成個人簡歷信息

代碼部分

HomeController.cs :

public async Task<IActionResult> ToPdf(){    PdfDocument pdfDocument = new PdfDocument();    HtmlToPdf converter = new HtmlToPdf();//實例化一個html到pdf轉換器對象    converter.Options.PdfPageOrientation = PdfPageOrientation.Portrait;//設置頁面方向    converter.Options.PdfPageSize = PdfPageSize.A4;//設置頁面大小    converter.Options.MarginTop = 10;//設置頁邊距    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);//第一種方法，使用RazorEngine.NetCore讀取Cshtml文件    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));} 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 :

Css樣式文件：

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)

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>();
