1 使用Office自帶的庫
前提是本機須安裝office才能運行,且不同的office版本之間可能會有兼容問題,從Nuget下載 Microsoft.Office.Interop.Excel
讀寫代碼如下:
using Microsoft.Office.Interop.Excel; using Excel = Microsoft.Office.Interop.Excel; private void btn_Office_Click(object sender, EventArgs e) { string importExcelPath = "E:\\import.xlsx"; string exportExcelPath = "E:\\export.xlsx"; //創建 Excel.Application xlApp = new Excel.Application(); xlApp.DisplayAlerts = false; xlApp.Visible = false; xlApp.ScreenUpdating = false; //打開Excel Excel.Workbook xlsWorkBook = xlApp.Workbooks.Open(importExcelPath, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing); //處理數據過程,更多操作方法自行百度 Excel.Worksheet sheet = xlsWorkBook.Worksheets[1];//工作薄從1開始,不是0 sheet.Cells[1, 1] = "test"; //另存 xlsWorkBook.SaveAs(exportExcelPath, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing); //關閉Excel進程 ClosePro(xlApp, xlsWorkBook); } public void ClosePro(Excel.Application xlApp, Excel.Workbook xlsWorkBook) { if (xlsWorkBook != null) xlsWorkBook.Close(true, Type.Missing, Type.Missing); xlApp.Quit(); // 安全回收進程 System.GC.GetGeneration(xlApp); IntPtr t = new IntPtr(xlApp.Hwnd); //獲取句柄 int k = 0; GetWindowThreadProcessId(t, out k); //獲取進程唯一標志 System.Diagnostics.Process p = System.Diagnostics.Process.GetProcessById(k); p.Kill(); //關閉進程 }
2. 使用NPOI
地址:https://github.com/tonyqus/npoi
在不安裝office的時候也是可以讀寫的,速度很快,從Nuget下載 NPOI
讀寫代碼如下:
using System.IO; using NPOI; using NPOI.SS.UserModel; private void btn_NPOI_Click(object sender, EventArgs e) { string importExcelPath = "E:\\import.xlsx"; string exportExcelPath = "E:\\export.xlsx"; IWorkbook workbook = WorkbookFactory.Create(importExcelPath); ISheet sheet = workbook.GetSheetAt(0);//獲取第一個工作薄 IRow row = (IRow)sheet.GetRow(0);//獲取第一行 //設置第一行第一列值,更多方法請參考源官方Demo row.CreateCell(0).SetCellValue("test");//設置第一行第一列值 //導出excel FileStream fs = new FileStream(exportExcelPath, FileMode.Create, FileAccess.ReadWrite); workbook.Write(fs); fs.Close(); }
3. 使用ClosedXml
地址:https://github.com/ClosedXML/ClosedXML
從Nuget下載ClosedXml
讀寫代碼如下:
using ClosedXML; using ClosedXML.Excel; private void btn_ClosedXML_Click(object sender, EventArgs e) { string importExcelPath = "E:\\import.xlsx"; string exportExcelPath = "E:\\export.xlsx"; var workbook = new XLWorkbook(importExcelPath); IXLWorksheet sheet = workbook.Worksheet(1);//這個庫也是從1開始 //設置第一行第一列值,更多方法請參考官方Demo sheet.Cell(1, 1).Value = "test";//該方法也是從1開始,非0 workbook.SaveAs(exportExcelPath); }
4. 使用 spire.xls
地址:https://www.e-iceblue.com/Introduce/free-xls-component.html
spire分免費和收費,無特殊需求用免費即可
從Nuget下載Free Spire.xls For .NET
讀寫代碼如下:
using Spire.Xls; private void btnSpire_Click(object sender, EventArgs e) { string importExcelPath = "E:\\import.xlsx"; string exportExcelPath = "E:\\export.xlsx"; Spire.Xls.Workbook workbook = new Spire.Xls.Workbook(); workbook.LoadFromFile(importExcelPath); //處理Excel數據,更多請參考官方Demo Spire.Xls.Worksheet sheet = workbook.Worksheets[0]; sheet.Range[1,1].Text = "test";//該方法也是從1開始,非0 workbook.SaveToFile(exportExcelPath); }
5. EPPLUS
