C#.NET PrintDocument 自定义报表数据打印
2024-05-16 06:48:15
这是一个自定义的报表打印，是对PrintPreviewDialog的扩展和封装。PrintPreviewDialog是一个windows的打印预览控件，该类返回的就是一个PrintPreviewDialog对象了，直接显示该控件就可以了。
该报表主要包含两个方面的内容：一个是数据统计分析的饼状图（数据集是用DataTable保存的，，图形统计值分析DataTable的前两列）；另一个就是DataTable的数据集了，可以自己定义绘制的格式（当然得自己写代码了）。
效果预览图如下所示：
该类的源代码如下：
