詳解如何使用Net將HTML簡(jiǎn)歷導(dǎo)出為PDF格式
正文
現(xiàn)在有許多將HTML導(dǎo)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(nèi)容讀出來(lái),然后再轉(zhuǎn)為Pdf文檔
- 讀取cshtml內(nèi)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(jìn)行讀取。(注意兩種方法的cshtml內(nèi)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(gè)人Github,有需要的請(qǐng)自?。?a rel="external nofollow" target="_blank">github.com/WeiMing0803…

首先使用ChatGPT生成個(gè)人簡(jiǎn)歷信息

代碼部分
HomeController.cs :

PdfDocument pdfDocument = new PdfDocument();
HtmlToPdf converter = new HtmlToPdf();//實(shí)例化一個(gè)html到pdf轉(zhuǎn)換器對(duì)象
converter.Options.PdfPageOrientation = PdfPageOrientation.Portrait;//設(shè)置頁(yè)面方向
converter.Options.PdfPageSize = PdfPageSize.A4;//設(shè)置頁(yè)面大小
converter.Options.MarginTop = 10;//設(shè)置頁(yè)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));
}

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)
