推荐答案

您要在纸上打印WinForms DataGridView的内容吗?这实际上是一项艰巨的任务，因为DataGridView是UI控件；它仅使每个单元格的部分在单元格矩形中可见，并且行数与视图矩形中显示的一样多.单元格和视图矩形均为固定大小.它还处理诸如滚动和编辑之类的事件.

You’re trying to print the contents of a WinForms DataGridView to paper? That is actually a difficult task because a DataGridView is a UI control; it renders only the parts of each cell visible in the cell rectangle for as many rows as are displayed in the view rectangle. Both the cell and view rectangles are fixed sizes. It also handles events like scrolling and editing.

如果要将视图中的所有数据打印到一张纸上，则必须将所有单元格内容(甚至是未渲染的内容)对于所有行(甚至视图中未加载的行)显示为可变大小System.Drawing.Graphics实例大到足以容纳整个单元格内容，并组装单元格以适合固定大小的Page矩形，处理布局和分页，并避免Graphics矩形超出页面矩形.

If you want to print all the data in the view to a piece of paper, you will have to show all cell contents, even contents not rendered, for all rows, even rows not loaded in the view, to variable-sized System.Drawing.Graphics instances large enough to hold the entire cell contents, and assemble the cells to fit in a fixed-size Page rectangle, handling layout and pagination, and avoiding Graphics rectangles outside the page rectangle.

我的建议是使用报告生成库，例如报表查看器或 nReports .

My advice is to use a report generation library like Report Viewer or nReports.

如果您只是学习打印或有非常简单的需求，则可以简单地遍历数据并将单元格内容绘制到纸上的固定边距；有一个代码项目文章执行此操作.

If you're just learning printing, or have extremely simple needs, you can simply loop through your data and draw the cell contents to fixed margins on the paper; there is a Code Project article on doing this.
