Question

我正在编码一个SQL客户端，您可以在其中将DataGridView导出到CSV（Excel）。问题是我在名为“ ID”的单元中有多个条目，就像ID的21倍是4倍，但电话号码不同。

这是我目前的代码：

private void ButtonDataGridInCSVExport(object sender, EventArgs e)
{
    if (dataGridViewResult.Rows.Count == 0)
    {
        return;
    }
    StringBuilder stringBuilder = new StringBuilder();

    string csvheader = "";
    for (int i = 0; i < dataGridViewResult.Columns.Count; i++)
    {
        csvheader += dataGridViewResult.Columns[i].Name + ";";
    }

    stringBuilder.Append(csvheader + Environment.NewLine);

    foreach (DataGridViewRow dataGridViewRow in dataGridViewResult.Rows)
    {
        if (!dataGridViewRow.IsNewRow)
        {

            for (int c = 0; c < dataGridViewRow.Cells.Count; c++)
            {
                stringBuilder.Append(dataGridViewRow.Cells[c].FormattedValue + ";");
            }
            stringBuilder.Append(Environment.NewLine);
        }
    }
    SaveFileDialog saveFileDialog = new SaveFileDialog();
    saveFileDialog.Filter = "CSV files (*.csv)|*.csv";
    if (saveFileDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    {
        using (System.IO.StreamWriter sw = new System.IO.StreamWriter(saveFileDialog.FileName, false, Encoding.UTF8))
        {
            sw.WriteLine(stringBuilder.ToString());
            MessageBox.Show("CSV file saved.");
        }
    }
}

有人知道如何做到这一点吗？

这是现在的样子： How it looks like now

它应该是这样的： How it should look like

对多个DataGridView列进行排序，然后导出为CSV
