详解如何使用Net将HTML简历导出为PDF格式-IT俱乐部

正文

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）

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 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 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

删除 @model PdfReportModel

将@Html.Raw(@style) 修改为 @@Raw(@style)
