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
