接着上一篇：上一篇寫了安裝，這篇直接搞定批量列印，A4紙橫版豎版頁面設計，正式開始。（我的表達不怎麼好，我盡量發圖檔都是程式員一點就通）
一、界面展示
忽略界面設計醜
檢視預覽界面，因為有資料就不截全屏了，盒号是我自己加的，我們自己的業務邏輯。
三、核心代碼，批量列印（參考代碼連結，放到文章結尾處）

2 {
3 rvDoc.LocalReport.DataSources.Add(new ReportDataSource("DataSet1", 你的資料));
4 //注意自己的路徑，這塊我寫到配置檔案，來區分測試跟線上路徑。
5 if (PublicProperty.RdlcPath == "Debug")
6 {
7 rvDoc.LocalReport.ReportPath = @"..\..\ReportForm\GTTKWenShuArchives.rdlc";

9 else
10 {
11 rvDoc.LocalReport.ReportPath = Application.StartupPath + "\\ReportForm\\GTTKWenShuArchives.rdlc";
12 }
13 //開始列印，第二個參數是選擇列印機名稱
14 BillPrint.Run(rvDoc.LocalReport, (string)printerList.Invoke(new obj_delegate(() => { return printerList.SelectedItem.ToString(); })));
15 }
16 } 四、設計報表一些注意事項（可以用差之毫厘失之千裡來形容）
- A4豎版列印，标頭設計寬 ，長隻能小于等于寬，要是大于就會出現空白頁情況。
vs2017使用rdlc實作批量列印 - A4橫版列印，标頭設計寬 ，長度跟豎版一樣，注意這個數字是我一點點試出來的，多一點就會出現表的列顯示不全，會跑到第二頁裡面，大家也可以自己試試。
vs2017使用rdlc實作批量列印 - 要想每一頁都顯示标題，隻能把标題加入到頁眉之中，注意 頁眉的底部一定要跟表重合否則到第二頁跟上邊距會跟第一頁不一樣，具體什麼樣自己試一下就知道了，
vs2017使用rdlc實作批量列印 - 表要是想加實線，注意設計的時候 ，這個大家一試便知。
vs2017使用rdlc實作批量列印 - 要想每一頁都顯示表的标題部分可以這麼設計
vs2017使用rdlc實作批量列印 - 剩下的内容的字型啊間距啊，就根據自己需求自己調吧，注意設計的時候盡量表要與兩邊重合，标題要與頂部重合，因為他預設是上下左右間距都是2CM，你要是有距離你列印出來就不好看了，這個自己試試就知道了。
