Question

我编写了一个编写文件的尖锐控制台应用程序，现在我要打印它。我在搜索时看到了很多例子，但其中很多都以表格和按钮开头，我不希望用户按任何按钮，因为我已经知道文件，字体和大小，我只想打印文档。我找到的每个应用程序都是一个Windows窗体应用程序，你能告诉我如何从控制台应用程序调用它吗？

如果问题有点基础，我很抱歉，我刚开始学习。

Answer 1

您可以使用PrintDocument对象

这是来自MSDN的示例代码：

using System;
using System.IO;
using System.Drawing;
using System.Drawing.Printing;
using System.Windows.Forms;

 public class PrintingExample 
 {
     private Font printFont;
     private StreamReader streamToPrint;
     static string filePath;


     public PrintingExample() 
     {
         Printing();
     }

     // The PrintPage event is raised for each page to be printed. 
     private void pd_PrintPage(object sender, PrintPageEventArgs ev) 
     {
         float linesPerPage = 0;
         float yPos =  0;
         int count = 0;
         float leftMargin = ev.MarginBounds.Left;
         float topMargin = ev.MarginBounds.Top;
         String line=null;

         // Calculate the number of lines per page.
         linesPerPage = ev.MarginBounds.Height  / 
            printFont.GetHeight(ev.Graphics) ;

         // Iterate over the file, printing each line. 
         while (count < linesPerPage && 
            ((line=streamToPrint.ReadLine()) != null)) 
         {
            yPos = topMargin + (count * printFont.GetHeight(ev.Graphics));
            ev.Graphics.DrawString (line, printFont, Brushes.Black, 
               leftMargin, yPos, new StringFormat());
            count++;
         }

         // If more lines exist, print another page. 
         if (line != null) 
            ev.HasMorePages = true;
         else 
            ev.HasMorePages = false;
     }

     // Print the file. 
     public void Printing()
     {
         try 
         {
            streamToPrint = new StreamReader (filePath);
            try 
            {
               printFont = new Font("Arial", 10);
               PrintDocument pd = new PrintDocument(); 
               pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);
               // Print the document.
               pd.Print();
            } 
            finally 
            {
               streamToPrint.Close() ;
            }
        } 
        catch(Exception ex) 
        { 
            MessageBox.Show(ex.Message);
        }
     }

     // This is the main entry point for the application. 
     public static void Main(string[] args) 
     {
        string sampleName = Environment.GetCommandLineArgs()[0];
        if(args.Length != 1)
        {
           Console.WriteLine("Usage: " + sampleName +" <file path>");
           return;
        }
        filePath = args[0];
        new PrintingExample();
     }
 }

确保将System.Drawing引用（System.Drawing.dll）添加到项目中。

using System.Drawing;
using System.Drawing.Printing;

namespace PrintingFromConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            PrintDocument doc = new PrintDocument();
            doc.PrintPage += new PrintPageEventHandler(doc_PrintPage);
            doc.Print();
        }

        private static void doc_PrintPage(object sender, PrintPageEventArgs e)
        {
            e.Graphics.DrawString("text", SystemFonts.DefaultFont, Brushes.Black, new PointF(100f, 100f));
            e.HasMorePages = false;
        }
    }
}

我已使用Microsoft XPS Document Writer和Bullzip PDF Printer测试了此代码 - 两者都按预期工作。

Answer 3

  string fl = Application.StartupPath + "\\BarCode.txt";
  string StrFileName = "Barcode.txt";
  int intFN;
  intFN = FileSystem.FreeFile();
  FileSystem.FileOpen(intFN, fl, OpenMode.Output, OpenAccess.Default,OpenShare.Default, 1024);
  // Write Text In File FileSystem.PrintLine(intFN, "TEST");
  FileSystem.FileClose(intFN);
  Microsoft.VisualBasic.Interaction.Shell(Application.StartupPath + "\\PRINT.BAT " + pStrFileName, AppWinStyle.Hide, false, -1);

现在创建新的批处理文件iePRINT.BAT并粘贴下面的命令： -

Type %1>\\ "PRINTER PATH WITHOUT QUOTES"

将此命令写入记事本并另存为PRINT.BAT文件运行应用程序

以c sharp打印文件
