C#中如何實現EXCEL轉換成TXT文檔

這篇文章主要為大家展示了“C#中如何實現EXCEL轉換成TXT文檔”，內容簡而易懂，條理清晰，希望能夠幫助大家解決疑惑，下面讓小編帶領大家一起研究并學習一下“C#中如何實現EXCEL轉換成TXT文檔”這篇文章吧。

C#數據轉換前excel中的數據格式如下:

設備名稱 規格型號 設備編號  使用部門 固定資產編號

電腦1 IBM5660 10001 管理部 100010001

電腦2 IBM5661 10002 研發部 100010002

電腦3 IBM5662 10003 管理部 100010003

C#數據轉換到TXT文檔的格式:

"檢測設備資產標簽","設備名稱","電腦1","規格型號","IBM5660","設備編號","10001","使用部門","管理部","固定資產編號","100010001"

"檢測設備資產標簽","設備名稱","電腦2","規格型號","IBM5661","設備編號","10002","使用部門","研發部","固定資產編號","100010002"

"檢測設備資產標簽","設備名稱","電腦3","規格型號","IBM5662","設備編號","10003","使用部門","管理部","固定資產編號","100010003"
end
