点击dgv某列的单元格时触发事件的方法

private void DataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        if (e.ColumnIndex == 1) //第一列是 ID （隐藏），第二列才是图片（Pic）列
        {
            int rowIndex = this.dataGridView1.CurrentRow.Index; // 取得当前单元格的行Index 
            string pic = dataGridView1.Rows[rowIndex].Cells["Pic"].Value.ToString();
            byte[] str = Convert.FromBase64String(pic);

            Image image = GetImage(str);
            this.pictureBox1.Image = image;
        }
