一、WkHtmlToPdfDotNet简介WkHtmlToPdfDotNet是基于本地wkhtmltopdf包的.NETCore类库。它主要通过webkit引擎将html页面转换成pdf文件。并且支持在Windows、Docker、Linux、MacOSX上运行。主要功能是将在线URL转为pdf文件或直接将html代码转为pdf文件，支持css样式、图片等，导出的pdf文件与网站没有太大区别。今天就通过一个实际案例来给大家介绍下如何使用。有兴趣的朋友可以一起学习！官网：https://github.com/HakanL/WkHtmlToPdf-DotNet二、安装1、使用VisualStudio2019及以上版本创建.NETCore控制台程序。2.安装WkHtmlToPdfDotNet依赖包命令方式安装工具→NuGet包管理器→包管理器控制包安装命令如下：Install-PackageHaukcode.WkHtmlToPdfDotNet直接通过Nuget包搜索安装工具→NuGet包管理器→NuGet管理解决方案包3.实现代码usingSystem;usingSystem.IO;usingWkHtmlToPdfDotNet;namespaceHtmlToPdf{classProgram{//https://github.com/HakanL/WkHtmlToPdf-DotNet//安装依赖包Install-PackageHaukcode.WkHtmlToPdfDotNetstaticvoidMain(string[]args){//ConvertHtmlToPdf();ConvertUrlToPdf();}//////基于html导出pdf///privatestaticvoidConvertHtmlToPdf(){varconverter=newBasicConverter(newPdfTools());//绑定转换时处理事件日志converter.PhaseChanged+=Converter_PhaseChanged;converter.ProgressChanged+=Converter_ProgressChanged;converter.Finished+=Converter_Finished;converter.Warning+=Converter_Warning;converter.Error+=转换器错误；//pdf样式设置vardoc=newHtmlToPdfDocument(){GlobalSettings={ColorMode=ColorMode.Color,Orientation=Orientation.Landscape,PaperSize=PaperKind.A4,},Objects={newObjectSettings(){PagesCount=true,HtmlContent=@"你好
