C# code to output to TAB delimited file

I have a function that outputs the data i want to a comma separated file, but how can i ajust this to output to a TAB separated file? i was thinking it would be just /t where the "," are.

But that didnt seem to work. An i missing something?

Just for your information, DataGrid is actually a dataGridView.
private void ExportGridToCsv(string file)
{
    StreamWriter writer = new StreamWriter(file);
 
    if (DataGrid.Rows.Count > 0)
    {
        foreach (DataGridViewColumn col in DataGrid.Columns)
        {
            if (col.Index == DataGrid.Columns.Count - 1)
            {
                writer.WriteLine(col.HeaderText);
            }
            else
            {
                writer.Write(string.Concat(col.HeaderText, ","));
            }
        }
 
        foreach (DataGridViewRow row in DataGrid.Rows)
        {
            
                foreach (DataGridViewCell cell in row.Cells)
                {
                    if (cell.OwningColumn.Index == DataGrid.Columns.Count - 1)
                    {
                        if (cell.Value != null)
                            writer.WriteLine(cell.Value.ToString());
                        else
                            writer.WriteLine("");
                    }
                    else
                    {
                        if (cell.Value != null)
                            writer.Write(string.Concat(cell.Value.ToString(), ","));
                        else
                            writer.Write(string.Concat("", ","));
                    }
                }
            
        }
    }
 
    writer.Close();
}
