接着上一篇：上一篇写了安装，这篇直接搞定批量打印，A4纸横版竖版页面设计，正式开始。（我的表达不怎么好，我尽量发图片都是程序员一点就通）
一、界面展示
忽略界面设计丑
查看预览界面，因为有数据就不截全屏了，盒号是我自己加的，我们自己的业务逻辑。
三、核心代码，批量打印（参考代码链接，放到文章结尾处）

代码使用
1 using (ReportViewer rvDoc = new ReportViewer())
2 {
3 rvDoc.LocalReport.DataSources.Add(new ReportDataSource("DataSet1", 你的数据));
4 //注意自己的路径，这块我写到配置文件，来区分测试跟线上路径。
5 if (PublicProperty.RdlcPath == "Debug")
6 {
7 rvDoc.LocalReport.ReportPath = @"..\..\ReportForm\GTTKWenShuArchives.rdlc";
8 }
9 else
10 {
11 rvDoc.LocalReport.ReportPath = Application.StartupPath + "\\ReportForm\\GTTKWenShuArchives.rdlc";
12 }
13 //开始打印，第二个参数是选择打印机名称
14 BillPrint.Run(rvDoc.LocalReport, (string)printerList.Invoke(new obj_delegate(() => { return printerList.SelectedItem.ToString(); })));
15 }
16 }
四、设计报表一些注意事项（可以用差之毫厘失之千里来形容）
-
A4竖版打印，标头设计宽
，长只能小于等于宽，要是大于就会出现空白页情况。
-
A4横版打印，标头设计宽
，长度跟竖版一样，注意这个数字是我一点点试出来的，多一点就会出现表的列显示不全，会跑到第二页里面，大家也可以自己试试。
-
要想每一页都显示标题，只能把标题加入到页眉之中，注意
页眉的底部一定要跟表重合否则到第二页跟上边距会跟第一页不一样，具体什么样自己试一下就知道了，
-
表要是想加实线，注意设计的时候
，这个大家一试便知。
- 要想每一页都显示表的标题部分可以这么设计
-
剩下的内容的字体啊间距啊，就根据自己需求自己调吧，注意设计的时候尽量表要与两边重合，标题要与顶部重合，因为他默认是上下左右间距都是2CM，你要是有距离你打印出来就不好看了，这个自己试试就知道了。
五、结尾
把一些我参考的链接放出来，大家可以自行参考。
