将datagridview和label vaue导出为ex​​cel

Question

我有一个包含帐单详细信息的datagridview。还有一个包含总金额的标签。我想在Excel中将datagridview值添加到excel和datagridview值末尾的标签总数。

这里我使用一个函数将datagridview导出到excel。并在点击事件中调用它。

      private void ToCsV(DataGridView dGV, string filename)
    {
        string stOutput = "";
        // Export titles:
        string sHeaders = "";

        for (int j = 0; j < dGV.Columns.Count; j++)
            sHeaders = sHeaders.ToString() + Convert.ToString(dGV.Columns[j].HeaderText) + "\t";
        stOutput += sHeaders + "\r\n";
        // Export data.
        for (int i = 0; i < dGV.RowCount - 1; i++)
        {
            string stLine = "";
            for (int j = 0; j < dGV.Rows[i].Cells.Count; j++)
                stLine = stLine.ToString() + Convert.ToString(dGV.Rows[i].Cells[j].Value) + "\t";
            stOutput += stLine + "\r\n";
        }
        Encoding utf16 = Encoding.GetEncoding(1254);
        byte[] output = utf16.GetBytes(stOutput);
        FileStream fs = new FileStream(filename, FileMode.Create);
        BinaryWriter bw = new BinaryWriter(fs);
        bw.Write(output, 0, output.Length); //write the encoded file
        bw.Flush();
        bw.Close();
        fs.Close();
    }

现在我想将标签值添加到excel数据的末尾。我看过添加标签值的示例。但我的问题是我想在excel中的数据末尾添加它。所以它可以称为总数。我怎样才能做到这一点。我坚持了下来。有人能帮助我吗？

考虑从DataTable填充数据网格视图。您可以使用开源的EPPlus库。从网上下载并在您的应用程序中引用。这是代码..

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);    

 //Here you can add your Label value to whatever cells you want..for example- A1 or something

var ms = new System.IO.MemoryStream();
pck.SaveAs(ms);
ms.WriteTo(Response.OutputStream);                          
}
