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"
