c# 通过html导出pdf，带分页

通过NuGet安装

Pechkin
Pechkin.Synchronized

一下示例是控制台应用程序

static void btnCreate() {
            SynchronizedPechkin sc = new SynchronizedPechkin(new GlobalConfig()
                .SetMargins(new Margins() { Left = , Right = , Top = , Bottom =  }) //设置边距
                .SetPaperOrientation(false) //设置纸张方向为纵向
                .SetPaperSize(MillimetersToPixelsWidth(), MillimetersToPixelsWidth())); //设置纸张大小50mm * 100mm
