我正在使用EPPlus库在Excel中导出报告。其中一列是日期类型,但在导出到Excel后,当我打开该文件时,它会将该列视为" General"除非我右键单击它并将其类型设置为"日期"。
以下是我的代码:
private void ExportToExcel(DataTable dataTable)
{
//Althought the column type is already date in dataTable but even if I use following line Excel doesn't treat it as Date
dataTable.Columns["Created On"].DataType = typeof(DateTime);
foreach (DataRow row in dataTable.Rows)
{
row["Created On"] = Convert.ToDateTime(row["Created On"].
ToString()).ToString("yyyy-MM-dd");
}
ExcelPackage excel = new ExcelPackage();
var workSheet = excel.Workbook.Worksheets.Add("MyReport");
var totalCols = dataTable.Columns.Count;
var totalRows = dataTable.Rows.Count;
string fileName = "MyReport[" + DateTime.Now.ToString("yyyy-MM-dd") + "].xlsx";
for (var col = 1; col <= totalCols; col++)
{
workSheet.Cells[1, col].Value = dataTable.Columns[col - 1].ColumnName;
workSheet.Cells[1, col].Style.Font.Bold = true;
}
for (var row = 1; row <= totalRows; row++)
{
for (var col = 0; col < totalCols; col++)
{
workSheet.Cells[row + 1, col + 1].Value = dataTable.Rows[row - 1][col];
}
}
workSheet.Cells.Style.Font.Size = 11;
workSheet.Cells.AutoFitColumns();
//Rest of the code
}
以下是关于此列在Excel中的外观的截图。
如何确保Excel将我的日期列视为日期?
答案 0 :(得分:1)
要在epplus中将文本设置为DateTime
格式,您需要设置单元格的格式类型
EG:
1)对于简单的短日期模式
workSheet.Cells[row, 3].Style.Numberformat.Format = DateTimeFormatInfo.CurrentInfo.ShortDatePattern;
2)如果你想要特定的格式,如日期时间,时间,小时等,那么
workSheet.Column(dateColIndex).Style.Numberformat.Format = "mm/dd/yyyy hh:mm:ss AM/PM";
