我需要这个格式与sqlite3相同，这是我的代码。

 SQLiteCommand myCommand = new SQLiteCommand();
            myCommand.Connection = m_dbConnection;


            myCommand.CommandText = "select CompanyId,DateTime,Serial,ShortDeviceId,MatricolaA,Upper(Targa),CommonRoadDescription,RoadCivicNumber,GpsAddress,VerbaliVehicleTypeDescription,VehicleBrandDescription,VehicleModelDescription,CommonColorVehicleDescription,VerbaliRuleOneCode,VerbaliRuleOneDescription,VerbaliClosedNoteDescription,VerbaliRuleOnePoints,VerbaliMissedNotificationDescription  from  VerbaliData";
            //myCommand.Connection = myConn;
            DataTable data = new DataTable();
            SQLiteDataAdapter myAdapter = new SQLiteDataAdapter(myCommand);
            //myAdapter.SelectCommand = myCommand;

            myAdapter.Fill(data);
            dataGridView1.DataSource = data;

            this.dataGridView1.Refresh();

            if (dataGridView1.RowCount > 0)
            {
                string value = "";
                DataGridViewRow dr = new DataGridViewRow();
                StreamWriter swOut = new StreamWriter("I:/test12.csv");

                for (int i = 0; i <= dataGridView1.Columns.Count - 1; i++)
                {
                    if (i > 0)
                    {
                        swOut.Write(",");
                    }
                    swOut.Write(dataGridView1.Columns[i].HeaderText);
                }

                swOut.WriteLine();

                for (int j = 0; j <= dataGridView1.Rows.Count - 1; j++)
                {
                    if (j > 0)
                    {
                        swOut.WriteLine();
                    }

                    dr = dataGridView1.Rows[j];

                    for (int i = 0; i <= dataGridView1.Columns.Count - 1; i++)
                    {
                        if (i > 0)
                        {
                            swOut.Write(",");
                        }


                        value = dr.Cells[i].Value.ToString();
                        value = value.Replace(',', ' ');
                        value = value.Replace(Environment.NewLine, " ");

                        swOut.Write(value);
                    }
                }
                swOut.Close();
            }m_dbConnection.Close();

将日期值写入CSV文件时，请用＆＃34;将其括起来。（双引号）符号。

检查：但在此之前打开记事本中的CSV文件，看看如何在那里写入值。通常，CSV文件与Excel相关联，如果您使用Excel打开它，它将尝试根据您当前的区域设置来解析值。

表导出为CSV不保留SQLite日期格式
