dll版本：NPOI2.0 dotnet2.0版本
这两天要做个excel导入的功能，想到以前用过NPOI，感觉很给力，今天写了个DEMO，写的时候还算顺利，毕竟以前用过，还是想记录下来，留着以后直接复制
把excel数据读取并拼接到DataTable中，为了使用SqlBulkCopy一次性拷贝到数据库中
1 IWorkbook workbook = null; 2 string fileExt = Path.GetExtension(path); 3 try 4 { 5 using (var file = new FileStream(path, FileMode.Open, FileAccess.Read)) 6 { 7 if (fileExt == ".xls") 8 workbook = new HSSFWorkbook(file); 9 else if (fileExt == ".xlsx") 10 workbook = new XSSFWorkbook(file); 11 else 12 { 13 14 } 15 } 16 } 17 catch (Exception ex) 18 { }
1 //获取sheet页 2 var sheet = workbook.GetSheetAt(0); 3 //获取总条数 4 int RowCount = sheet.LastRowNum; 5 //获取sheet页的第一条数据 6 IRow firstRow = sheet.GetRow(0); 7 //获取总列数 8 int CellCount = firstRow.LastCellNum; 9 10 DataTable dt = new DataTable(); 11 for (int j = 0; j < CellCount; j++) 12 { 13 string value = firstRow.GetCell(j).StringCellValue; 14 DataColumn dc = new DataColumn(value, typeof(String)); 15 dt.Columns.Add(dc); 16 } 17 18 for (int i = 1; i <= RowCount; i++) 19 { 20 IRow row = sheet.GetRow(i); 21 DataRow dr = dt.NewRow(); 22 for (int j = 0; j < CellCount; j++) 23 { 24 object obj = row.GetCell(j); 25 if (obj != null) 26 dr[j] = obj.ToString(); 27 else 28 dr[j] = ""; 29 } 30 dt.Rows.Add(dr); 31 }
最后使用SqlBulkCopy
SqlBulkCopy sqlbulkcopy = new SqlBulkCopy(connectionString, SqlBulkCopyOptions.UseInternalTransaction); sqlbulkcopy.DestinationTableName = "Table_1";//数据库中的表名 sqlbulkcopy.WriteToServer(dataset.Tables[0]);
