【问题描述】:
我已将 DataTable 导出到 excel 文件。但是当我打开 excel 文件时,日期时间格式发生了变化。
当我导出数据 DateTime 字段时包含“7/21/2016 12:00:00 AM”值。当我打开 excel 文件时,日期时间字段显示“7/21/2016 0:00”值。
但是当我在 excel 文件公式栏中检查 DateTime 值时显示正确的“7/21/2016 12:00:00 AM”。
有什么办法可以解决这个问题吗?
我使用以下代码将 DataTable 导出到 excel:
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.ContentType = "application/ms-excel";
HttpContext.Current.Response.Write(@"<!DOCTYPE HTML PUBLIC ""-//W3C//DTD HTML 4.0 Transitional//EN"">");
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + curEventName + ".xls");
HttpContext.Current.Response.Charset = "utf-8";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("windows-1250");
////sets font
HttpContext.Current.Response.Write("<font style='font-size:10.0pt; font-family:Calibri;'>");
HttpContext.Current.Response.Write("<BR><BR><BR>");
//sets the table border, cell spacing, border color, font of the text, background, foreground, font height
HttpContext.Current.Response.Write("<Table border='1' bgColor='#ffffff' " +
"borderColor='#000000' cellSpacing='0' cellPadding='0' " +
"style='font-size:10.0pt; font-family:\"Times New Roman\"; background:white;'> <TR>");
//am getting my grid's column headers
int columnscount = dt_exportResponse.Columns.Count;
for (int j = 0; j < columnscount; j++)
{ //write in new column
HttpContext.Current.Response.Write("<Td>");
//Get column headers and make it as bold in excel columns
HttpContext.Current.Response.Write("<B>");
HttpContext.Current.Response.Write(dt_exportResponse.Columns[j].ColumnName);
HttpContext.Current.Response.Write("</B>");
HttpContext.Current.Response.Write("</Td>");
}
HttpContext.Current.Response.Write("</TR>");
foreach (DataRow row in dt_exportResponse.Rows)
{//write in new row
HttpContext.Current.Response.Write("<TR>");
for (int i = 0; i < dt_exportResponse.Columns.Count; i++)
{
HttpContext.Current.Response.Write("<Td>");
HttpContext.Current.Response.Write(row[i].ToString());
HttpContext.Current.Response.Write("</Td>");
}
HttpContext.Current.Response.Write("</TR>");
}
HttpContext.Current.Response.Write("</Table>");
HttpContext.Current.Response.Write("</font>");
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
