        private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)        {            string buttonText = this.dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();            if (buttonText == "更新")            {                string url = this.dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString();                string aid = this.dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString();                string imageURL = "http://m119.mail.qq.com" + this.GetImageURL(url);                string newImage = this.CreateImage(imageURL, aid);                this.dataGridView1.Rows[e.RowIndex].Cells[7].Value = System.Drawing.Image.FromFile(newImage);            }            if (buttonText == "提交")            {                string userInput = this.dataGridView1.Rows[e.RowIndex].Cells[9].Value.ToString();                if (userInput.Length != 4)                {                    MessageBox.Show("貌似你輸入不正確");                    return;                }                string url = this.dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString();                string aid = this.dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString();                Regex reg = new Regex("&re=(.+?)&");                string re = this.RegStr(reg,url);                Regex rego = new Regex("&sg=(.+?)$");                string sg = this.RegStr(rego, url);            }
