从C＃/。NET打印的最好方法？ [英] Best way to print from c# / .net?

问题描述

什么是打印从C＃的东西的最佳方式/。NET？

What is the best way to print stuff from c#/.net?

的问题是关于单页以及含有大量的页的报告。

The question is in regard to single pages as well as to reports containing lots of pages.

这将是巨大的，获得包含每个人的主要特征和陷阱最常见的打印库列表。

It would be great to get a list of the most common printing libs containing the main features and gotchas of each of them.

推荐答案

有关报道，我用的是RDLC控制。

For reports, I use the RDLC control.

对于一切，我用在.NET中固有的打印对象。

For everything else, I use the inherent printing objects within .NET.

修改 固有的打印对象在System.Drawing.Printing命名空间中找到的所有。当您使用PrintDialog类或打印previewDialog在一个WinForms（或WPF）应用程序，这是给你翻身的控制这些对象。

Edit The inherent printing objects are all found in the System.Drawing.Printing namespace. When you use the PrintDialog or the PrintPreviewDialog in a WinForms (or WPF) application, it is to these objects that you're turning over control.

的基本概念是，你正在绘制到打印机。这种最简单的形式是：

The fundamental concept is that you're drawing to the printer. The simplest form of this is:

Sub MyMethod()
     Dim x as New PrintDocument
     AddHandler x.PrintPage, AddressOf printDoc_PrintPage
     x.Print
End Sub
Sub printDoc_PrintPage( sender as Object,  e as PrintPageEventArgs)
      Dim textToPrint as String= ".NET Printing is easy"
      dim printFont as new Font("Courier New", 12)
      dim leftMargin as int= e.MarginBounds.Left
      dim topMargin as int = e.MarginBounds.Top
      e.Graphics.DrawString(textToPrint, printFont, Brushes.Black, leftMargin, topMargin)
End Sub

这里发生的是，当我的对象（X）发送打印命令，它提出了打印页面事件（其目的是在同一时间打印1页）。此事件然后使用PrintPageEventArgs的图形属性直接绘制相关的字符串，打印后台处理程序。

What's happening here is that when my object (x) is sent the print command, it raises the "PRINT PAGE" event (which is designed to print 1 page at a time). This event then uses the Graphics attribute of the PrintPageEventArgs to draw the relevant string directly to the print spooler.

这里有一个教程和一快速谷歌搜索.NET打印教程返回有点超过200K的结果。

Here's one tutorial, and a quick Google search for ".NET printing tutorial" returns a bit over 200K results.
