如何打印在C＃中使用PrintDialog类的文档 [英] How to print a document using PrintDialog in C#

问题描述

下面是我的示例代码。但其打印空白页

  printDocument1.DocumentName =C：\a.pbf; // PrintDocument的printDocument1 
 printDialog1.Document = printDocument1; 
 printDialog1.AllowPrintToFile = TRUE; 
 printDialog1.AllowSelection = TRUE; 
 printDialog1.AllowSomePages = TRUE; 
 printDialog1.PrintToFile = TRUE; 
如果（printDialog1.ShowDialog（）== DialogResult.OK）
 printDocument1.Print（）; 
  

请告诉我不对的？请帮我。

解决方案

您需要处理的 的PrintPage 事件实际提供的内容; MSDN有一个完整的例子。该 DocumentName 是纯粹的东西展现给用户 - 它的不的现有文件的路径为神奇打印

Here is my Sample code . But its printing an Empty page

            printDocument1.DocumentName = "C:\a.pbf";// PrintDocument printDocument1
            printDialog1.Document = printDocument1;
            printDialog1.AllowPrintToFile = true;
            printDialog1.AllowSelection = true;
            printDialog1.AllowSomePages = true;
            printDialog1.PrintToFile = true;
            if (printDialog1.ShowDialog() == DialogResult.OK)
                printDocument1.Print();

Whats wrong with this?. Please help me

解决方案

You need to handle the PrintPage event to actually provide the contents; MSDN has a full example. The DocumentName is purely something to show to the user - it is not the path of an existing file to magically print.

For printing an existing PDF, maybe look at this question
