c# 封裝“度分秒”與弧度之間的轉換 以及datagridview控件的應用

代碼：

datagridview   計算

 private void button1_Click(object sender, EventArgs e)

 

        {
            string[] sd = new string[dataGridView1.RowCount];//新建一個字符串數組存放觀測角度的原始值

            cr[0] = dmstorad(Convert.ToString(dataGridView1.Rows[0].Cells[2].Value));
            //獲取第一個坐標方位角，並將其轉換成弧度，放入cr[]數組第一個元素中
            dataGridView1.Rows[dataGridView1.RowCount - 1].Cells[0].Value = "總和";
                for(int i=1;i<dataGridView1.RowCount-2;i++)//從第二行開始循環計算 觀測角度累加值 坐標方位角 直到倒數第三行
