Web、winform打印、批量打印解決方案、excel套打模板

點擊下載Excel 快遞單套打模板

 

在網上找了很多都是.cab 或activex之類的控件比較麻煩、報表又不會，只能用excel了

 

需求很簡單,勾選多個訂單後,能夠批量打印每一個訂單的商品列表,由於是在Web上,我的解決方案如下：

 

1，服務器生成Excel 供客戶端下載打印(即本地打印)。

2，服務器自動打印(遠程打印)。

 

本地打印:

1，服務器生成excel；

2，下載

3，打印

 

遠程打印:

1，做一個目錄監聽程序；

2，生成excel；

3，目錄監聽程序調用excel,開始打印

 

這樣遠近基本都滿足了,唯一一點就是負責打印的機器需要安裝excel

 

以下附上一個excel操作的類:

如下調用即可:

ExcelControl  _excelApp = new ExcelControl();/*實例化*/

ExcelApp.SavefilePath = filePath;/*生成文件存放的位置*/
ExcelApp._SaveToExcel(/*這裏傳入datatable、或dataset*/）;

關於目錄監用到一個類fileSystemWatcher,自己查查就知道了..

 

監聽程序用到了devexpress控件,體積比較大,需要的可以點擊這裏下載
