C# 使用PrintDocument 绘制表格 完成 打印预览

C# 使用PrintDocument 绘制表格 完成 打印预览 DataTable

 

经过不断的Google与baidu，最终整理出来的打印类

主要是根据两个参考的类组合而成，稍微修改了一下，参考代码及来源见最后（其中一份是VB语言的）

其中遇到的一些问题也已经得到了解决（分页，打印预览点击打印内容缺失）

相关知识

PrintDocument

定义一个可再次使用的对象，该对象将输出发送到打印机。

命名空间:System.Drawing.Printing
程序集:System.Drawing（在 system.drawing.dll 中）

通常可以创建 PrintDocument 类的实例，设置描述打印方式的属性，然后调用 Print 方法开始打印进程。通过使用 PrintPageEventArgs 中包含的 Graphics 来处理用于指定打印输出的 PrintPage 事

PrintDocument.PrintPage 事件

当需要为当前页打印的输出时发生。

PrintDocument.Print 方法

开始文档的打印进程。

PrintPageEventArgs.HasMorePages 

获取或设置一个值，该值指示是否打印附加页。

打印多页时 要根据剩余页数判断并设置 HasMorePages 是否继续执行 PrintPage

打印预览中点击打印按钮，实际上会再次执行 PrintPage 事件，所以再打印完文档后 应该对相关属性进行重置

if (PrintingPageNumber > TotalPage)
 {
    Ev.HasMorePages = false;
    PrintingPageNumber = ;
    PrintRecordComplete = ;
 }
 else
 {
    Ev.HasMorePages = true;
