因为项目中要用到服务器端创建EXCEL模板 无法直接调用EXCEL 查了下发现NPOI很方便很简单就实现了
其中走了点弯路 第一次弄的时候发现输出的值是文本不是数字型无法直接计算公式 然后又发现打开报表公式没有自动计算 后来都解决了 详见代码
#region 报表处理
using (FileStream file = new FileStream(@"C:InetpubwwwrootClientBinRptBasicRpt_mrp_DepInOut.xls", FileMode.Open, FileAccess.Read))
{
NPOI.HSSF.UserModel.HSSFWorkbook book = new NPOI.HSSF.UserModel.HSSFWorkbook(file);
NPOI.SS.UserModel.ISheet sheet = book.GetSheet("Sheet1");
ExcelSetValue(sheet, 0, 0, dt.Rows[0]["myconame"].ToString() + kind);
ExcelSetValue(sheet, 3, 1, dt.Rows[0]["coname"].ToString());
ExcelSetValue(sheet, 3, 3, dt.Rows[0]["Tel"].ToString());
ExcelSetValue(sheet, 3, 6, dt.Rows[0]["sNum"].ToString());
ExcelSetValue(sheet, 4, 1, dt.Rows[0]["Address"].ToString());
ExcelSetValue(sheet, 4, 3, dt.Rows[0]["Lineman"].ToString());
ExcelSetValue(sheet, 4, 6, dt.Rows[0]["sdate"].ToString());
ExcelSetValue(sheet, 28, 4, dt.Rows[0]["AuditMan"].ToString());
ExcelSetValue(sheet, 28, 7, dt.Rows[0]["upby"].ToString());
int row = 7;
for (int i = 0; i < dtd.Rows.Count; i++)
{
ExcelSetValue(sheet, i + row, 0, dtd.Rows[i]["sNum"].ToString());
ExcelSetValue(sheet, i + row, 1, dtd.Rows[i]["itemname"].ToString());
ExcelSetValue(sheet, i + row, 02, dtd.Rows[i]["model"].ToString());
ExcelSetValue(sheet, i + row, 03, dtd.Rows[i]["unit"].ToString());
ExcelSetValue(sheet, i + row, 04, dtd.Rows[i]["num"].ToString());
ExcelSetValue(sheet, i + row, 05, dtd.Rows[i]["price"].ToString());
ExcelSetValue(sheet, i + row, 06, dtd.Rows[i]["sum"].ToString());
ExcelSetValue(sheet, i + row, 07, dtd.Rows[i]["remark"].ToString());
}
sheet.ForceFormulaRecalculation = true;
// 另存为
using (FileStream f = new FileStream(@"C:InetpubwwwrootClientBinRpt" + filename + ".xls", FileMode.Create, FileAccess.ReadWrite))
{
book.Write(f);
}
}
#endregion
其中的设置单元格值的方法
protected void ExcelSetValue(NPOI.SS.UserModel.ISheet sheet, int Row, int Cell,string sValue)
{
if (sheet.GetRow(Row) == null)
sheet.CreateRow(Row);
if (sheet.GetRow(Row).GetCell(Cell) == null)
sheet.GetRow(Row).CreateCell(Cell);
double d;
if (double.TryParse(sValue, out d))
{
sheet.GetRow(Row).GetCell(Cell).SetCellValue(d);
}
else
sheet.GetRow(Row).GetCell(Cell).SetCellValue(sValue);
}
