C# 打印PDF文件

在写这个标题的时候，我的心情是极度崩溃的，连续奋战N久之后，才把这个问题搞定，记录下吧！
首先找到
O2S.Components.PDFView4NET.dll
O2S.Components.PDFRender4NET.dll
FontBox-0.1.0-dev.dll
IKVM.GNU.Classpath.dll
IKVM.Runtime.dll
PDFBox-0.7.3.dll
这6个DLL找到之后才写后面的代码
这是引用的3个命名空间
using O2S.Components.PDFRender4NET;
using System.Drawing.Printing;
using O2S.Components.PDFRender4NET.Printing;

        /// <summary>

        /// 打印的代码

        /// </summary>

        /// <param name="url">要打印的PDF路径</param>

        private void printShow(string url)

        {

            PDFFile file = PDFFile.Open(url);

            PrinterSettings settings = new PrinterSettings();

            System.Drawing.Printing.PrintDocument pd = new System.Drawing.Printing.PrintDocument();

            settings.PrinterName = 打印机的名字;

            settings.PrintToFile = false;

            //设置纸张大小（可以不设置取，取默认设置）3.90 in,  8.65 in

            PaperSize ps = new PaperSize("Your Paper Name", config.Width, config.Height);

            ps.RawKind = 150; //如果是自定义纸张，就要大于118，（A4值为9，详细纸张类型与值的对照请看http://msdn.microsoft.com/zh-tw/library/system.drawing.printing.papersize.rawkind(v=vs.85).aspx）

            O2S.Components.PDFRender4NET.Printing.PDFPrintSettings pdfPrintSettings = new O2S.Components.PDFRender4NET.Printing.PDFPrintSettings(settings);

            pdfPrintSettings.PaperSize = ps;

            pdfPrintSettings.PageScaling = O2S.Components.PDFRender4NET.Printing.PageScaling.FitToPrinterMarginsProportional;

            pdfPrintSettings.PrinterSettings.Copies = 2;

            file.Print(pdfPrintSettings);

            file.Dispose();

        }
