Date time conversion while exporting datagrid value

Question

I am exporting my datagrid value in text file. And my system date format is "MM/dd/yyyy". Here in this code, Cell1 and Cell2 has date time value. At the screen, it's visible as "dd/MM/yyyy" format but while exporting it converts in my system format as "MM/dd/yyyy".

Please suggest or provide way to handle this conversion case, where system date time format is MM/dd/yyyy.

============================================

C#

void Export_Grid()
        {
            TextWriter sw = new StreamWriter(@"F:\\Attendance2013\\Export.txt");
            int rowcount = dataGridView1.Rows.Count;
            for (int i = 0; i < rowcount - 1; i++)
            {

                sw.WriteLine(dataGridView1.Rows[i].Cells[0].Value.ToString() + "|"
                + dataGridView1.Rows[i].Cells[1].Value.ToString() + "|"
                + dataGridView1.Rows[i].Cells[2].Value.ToString() + " "
                + dataGridView1.Rows[i].Cells[3].Value.ToString() + "|"
                + dataGridView1.Rows[i].Cells[4].Value.ToString() + "|"
                + dataGridView1.Rows[i].Cells[5].Value.ToString() + "");

            }
            sw.Close();
            MessageBox.Show("Data Exported Sucessfully");

        }

I'm not sure I follow what your issue is. As long as the value can be parsed by DateTime, all you need to do is format it to the desired style.

You can use like this...

String.Format("{0:MM/dd/yyyy}", GridView1.Rows[i].Cells[1].Value)

When you use the default ToString implementation on a DateTime value, it is formatted according to the current system settings. So since your PC is set to MM/dd/yyyy, that is the format of the date as a string that is generated. To avoid that, use a format strign with the ToString:

C#

dataGridView1.Rows[i].Cells[n].Value.ToString("dd/MM/yyyy")

You might also want to consider using a StringBuilder and File.WriteAllText instead of a stream and string concatenation - it'll probably be a lot quicker and more efficient.
