NOPI 导出 Excel 2007

代码：

    public static void ThisTo<T>( List<T> source, string[] colums, Func<T, object[]> action, string savePath, string sheetName = "")
         {
             XSSFWorkbook xssfworkbook = new XSSFWorkbook();
             ISheet sheet = xssfworkbook.CreateSheet(sheetName);
             IRow row = sheet.CreateRow();
             for (int i = ; i < colums.Length; i++)
             {
                 ICell cell = row.CreateCell(i);
                 cell.SetCellValue(colums[i]);
             }
             for (int i = ; i < source.Count; i++)
             {
                     IRow row1 = sheet.CreateRow(i + );
                      int colIndex = ;
                      row1.Cells.AddRange(action(source[i]).Select(p =>
                      {
                         var colCell = row1.CreateCell(colIndex,CellType.String);
                         colCell.SetCellValue(p.ToString());
                         colIndex++;
                         return colCell;
                     }));
             }
             MemoryStream stream = new MemoryStream();
             xssfworkbook.Write(stream);
             var buf = stream.ToArray();
             using (FileStream fs = new FileStream(savePath, FileMode.Create, FileAccess.Write))
             {
                 fs.Write(buf, , buf.Length);
                 fs.Flush();
             }
         }

调用：

  ThisTo<NAMES>(a, new string[] { "Name","Gender"}, p =>
             {
                 return new object[] {
                   p.Name,
                   p.Gender
                 };
             }, @"D:\ABCD.xlsx", "");

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。
