誰能給我發(fā)關于何使用winform導入導出excel方法具體實現(xiàn)winform有表格直接和excel關聯(lián)關于數(shù)據(jù)庫導出excel種excel嵌入winform需要窗口切換要用控件
調(diào)試錯誤下希望高手幫忙
命名空間Microsoft.Office存類型或命名空間名稱Interop(缺少程序集引用?) D:\vs\Excel\Excel\Form1.cs錯誤該解決
首先 先確定安裝了EXCEL沒有安裝了
VS能會自動添加組件也能沒有添加沒關系 因組件自己添加
第步 添加引用 也添加組件 所有解決方案里都有引用文件夾里點擊添加引用會看選項卡界面 點擊瀏覽
把excel文件夾下Microsoft.Office.Interop.Excel.dll組件添加進去再cs文件還得寫 using Microsoft.Office.Interop.Excel;
之具體導入EXCEL 或 導出代碼了 我里做了導入EXCEL給吧
希望能幫
