Date Format Problem

Apr 21 2024 7:51 AM

I use the codes below to transfer data from datagridview to Excel. The codes are quite fast and useful. But the only problem is with the date format. How can we get data in columns containing dates in short date format?

private void ToCsV(DataGridView dGV, string filename)
{
    Thread.CurrentThread.CurrentCulture = new CultureInfo("tr-TR");
    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; 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();
}
private void button2_Click(object sender, EventArgs e)
{
    SaveFileDialog sfd = new SaveFileDialog();
    sfd.Filter = "Excel Documents (*.xls)|*.xls";
    sfd.FileName = "Sinav Toplu Oturum Bilgileri.xls";
    if (sfd.ShowDialog() == DialogResult.OK)
    {

        ToCsV(dataGridView1, sfd.FileName); // Here dataGridview1 is your grid view name
    }
    MessageBox.Show("Sinav Toplu Oturum Bilgileri Excel formatinda masaüstüne kaydedildi!");
}
