NOPI 导出 Excel 2007
代码:
1 public static void ThisTo<T>( List<T> source, string[] colums, Func<T, object[]> action, string savePath, string sheetName = "") 2 { 3 XSSFWorkbook xssfworkbook = new XSSFWorkbook(); 4 ISheet sheet = xssfworkbook.CreateSheet(sheetName); 5 IRow row = sheet.CreateRow(0); 6 for (int i = 0; i < colums.Length; i++) 7 { 8 ICell cell = row.CreateCell(i); 9 cell.SetCellValue(colums[i]); 10 } 11 for (int i = 0; i < source.Count; i++) 12 { 13 IRow row1 = sheet.CreateRow(i + 1); 14 int colIndex = 0; 15 row1.Cells.AddRange(action(source[i]).Select(p => 16 { 17 var colCell = row1.CreateCell(colIndex,CellType.String); 18 colCell.SetCellValue(p.ToString()); 19 colIndex++; 20 return colCell; 21 })); 22 } 23 MemoryStream stream = new MemoryStream(); 24 xssfworkbook.Write(stream); 25 var buf = stream.ToArray(); 26 using (FileStream fs = new FileStream(savePath, FileMode.Create, FileAccess.Write)) 27 { 28 fs.Write(buf, 0, buf.Length); 29 fs.Flush(); 30 } 31 }
调用:
1 ThisTo<NAMES>(a, new string[] { "Name","Gender"}, p => 2 { 3 return new object[] { 4 p.Name, 5 p.Gender 6 }; 7 }, @"D:\ABCD.xlsx", "234");
说明:
方法中第一个参数为需导出数据,第二个参数为Excel列名,第三个为导出时数据排布顺序(与第二个参数相对应),第四参数为保存地址,第五参数为sheet名,
调用参照上述调用方法。
