C# 打印PDF文件

第一步：添加项目引用

安装控件后，创建一个新的项目（Windows窗体应用程序），找到控件的安装目录，在项目的“解决方案”窗口右击->添加引用，选择和项目.NET Framework版本对应的dll文件进行添加；

第二步：使用命名空间

using System.Windows.Forms; using System.Drawing.Printing; using Spire.Pdf;

第三步：创建一个新的PDF文档，并加载待打印的PDF文件

// 实例化一个word文档对象 PdfDocument doc = new PdfDocument(); doc.LoadFromFile(@"F:\test.pdf"); 第四步：（ 使用默认打印机打印所有页面） 选择打印机和设置打印页面范围

//选择默认打印机打印所有页面 //doc.PrintDocument.Print(); //选择打印机并设置打印页面范围 PrintDialog dialogPrint = new PrintDialog(); dialogPrint.AllowPrintToFile = true; dialogPrint.AllowSomePages = true; dialogPrint.PrinterSettings.MinimumPage = 1; dialogPrint.PrinterSettings.MaximumPage = doc.Pages.Count; dialogPrint.PrinterSettings.FromPage = 1; dialogPrint.PrinterSettings.ToPage = doc.Pages.Count; if (dialogPrint.ShowDialog() == DialogResult.OK) { doc.PrintFromPage = dialogPrint.PrinterSettings.FromPage; doc.PrintToPage = dialogPrint.PrinterSettings.ToPage; doc.PrinterName = dialogPrint.PrinterSettings.PrinterName; PrintDocument printDoc = doc.PrintDocument; dialogPrint.Document = printDoc; printDoc.Print(); }

运行结果，点击按钮，弹出右边窗口，便可以打印了
