I wrote a foreach loop for my datagridview to write all rows to txt file. I have a problem as it adds 2 empty lines at the end, as 1 row is full of empty cells after adding/reading to datagrid view. Is there any way to omit the last line or delete it in txt?

foreach (DataGridViewRow item in this.DB.Rows)
        {
            foreach (DataGridViewCell item2 in item.Cells)
            {   
                if(item2.Value != null)
                filewrite.Write(item2.Value.ToString() + " ");
            }
            filewrite.WriteLine("");
        }
