用EPPlus将DataTable导出到Excel
用EPPlus将DataTable导出到Excel
提问于 2012-12-02 21:31:50
我想用EPPlus将数据表导出到Excel文件中。该数据表有一个int类型的属性，所以我想在Excel文件中使用相同的格式。
有人知道如何将这样的DataTable导出到Excel吗？

using (ExcelPackage pck = new ExcelPackage(newFile))
{
ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Accounts");
ws.Cells["A1"].LoadFromDataTable(dataTable, true);
pck.Save();
}这对你来说应该是个好办法。如果您的字段被定义为整数，EPPlus将正确地将列转换为数字或浮点数。

如果你想在浏览器响应中下载
Response.Clear();
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("content-disposition", "attachment;filename=" + HttpUtility.UrlEncode("Logs.xlsx", System.Text.Encoding.UTF8));
using (ExcelPackage pck = new ExcelPackage())
{
ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Logs");
ws.Cells["A1"].LoadFromDataTable(dt, true);
var ms = new System.IO.MemoryStream();
pck.SaveAs(ms);
ms.WriteTo(Response.OutputStream);

要在浏览器中下载excelsheet表格，请使用HttpContext.Current.Response而不是Response，否则将得到Response is not available in this context. error.Here is my code
public void ExporttoExcel(DataTable table, string filename)
{
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
HttpContext.Current.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=GridData.xlsx");
using (ExcelPackage pack = new ExcelPackage())
{
ExcelWorksheet ws = pack.Workbook.Worksheets.Add(filename);
ws.Cells["A1"].LoadFromDataTable(table, true);
var ms = new System.IO.MemoryStream();
pack.SaveAs(ms);
ms.WriteTo(HttpContext.Current.Response.OutputStream);
}
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
