如何在datagridview输出的列之间添加简单文本？ C＃

Question

I am trying to convert datagridview to text file. So when i am using this code i am getting that text output. Ex.

"Start of the text! This 170 is number This 80 is number End of the text!"

This 170 and 80 numbers are generating from datagridview.

I want to get that output. Ex.

"Start of the text! This 170 is number 80 End of the text!"

So i dont want to add "This " and " is number" on second column.

Sorry for my bad English if this text is not understoodable.

private void button3_Click(object sender, EventArgs e)
    {
        TextWriter writer = new StreamWriter(@"C:\Users\ESTIT09\Desktop\test.txt");
        for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
        {
            writer.WriteLine("Start of the text!");
            for (int j = 0; j < dataGridView1.Columns.Count; j++)
            {
                writer.Write("This " + dataGridView1.Rows[i].Cells[j].Value.ToString() + " is number" + "\r\n");
            }

            writer.WriteLine("End of the text!");
        }
        writer.WriteLine("end sub");
        writer.Close();
    }

This should work. Replace your for loop with this block.

    for (int j = 0; j < dataGridView1.Columns.Count; j++)
                {
                    if(j==0) //change the index (0 or 1)for what you are looking for
                    {
                         writer.Write("This " + dataGridView1.Rows[i].Cells[j].Value.ToString() + " is number" + "\r\n");
                    }
                    else
                    {
                        writer.Write(dataGridView1.Rows[i].Cells[j].Value.ToString() + "\r\n");     
                    } 
                }
