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
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)
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); } }
Css样式文件:

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)
