如何將某些列從 datatable 獲取到 datagridview？

Question

我有一個數據表，我想從中提取某些信息（僅某些行和某些列）。 我正在嘗試使用下面的代碼，但是當我運行它時出現索引超出范圍錯誤，我不確定我正在做的是否是從數據表中僅獲取某些數據的最佳方法到數據網格視圖。 有任何想法嗎？

        currentRow = 0;
        int dataGridRow = 0;
        foreach (DataRow row in resultsDT.Rows)
        {
            string value = resultsDT.Rows[currentRow]["HighLow"].ToString();
            if (value.Equals("High") | value.Equals("Low"))
            {
                dataGridView2.Rows[dataGridRow].Cells["colHighLow"].Value = resultsDT.Rows[currentRow]["HighLow"];
                dataGridView2.Rows[dataGridRow].Cells["colDifference"].Value = resultsDT.Rows[currentRow]["Difference"];
                dataGridView2.Rows[dataGridRow].Cells["colMbrSep"].Value = resultsDT.Rows[currentRow]["MBRSEP"];
                dataGridView2.Rows[dataGridRow].Cells["colLocation"].Value = resultsDT.Rows[currentRow]["LOCATION"];
                dataGridView2.Rows[dataGridRow].Cells["colDistrict"].Value = resultsDT.Rows[currentRow]["DIST"];
                dataGridView2.Rows[dataGridRow].Cells["colAddress"].Value = resultsDT.Rows[currentRow]["ADDR1"];
                dataGridView2.Rows[dataGridRow].Cells["colMeter"].Value = resultsDT.Rows[currentRow]["METER"];
                dataGridView2.Rows[dataGridRow].Cells["colKWh"].Value = resultsDT.Rows[currentRow]["KWH"];
                dataGridRow++;
            }
            currentRow++;
        }

我只能猜測你需要的是

   currentRow = 0;
        int dataGridRow = 0;
        foreach (DataRow row in resultsDT.Rows)
        {
            string value = resultsDT.Rows[currentRow]["HighLow"].ToString();
            if (value.Equals("High") | value.Equals("Low"))
            {
                //THIS LINE
                dataGridView2.Rows.Add();

                dataGridView2.Rows[dataGridRow].Cells["colHighLow"].Value = resultsDT.Rows[currentRow]["HighLow"];
                dataGridView2.Rows[dataGridRow].Cells["colDifference"].Value = resultsDT.Rows[currentRow]["Difference"];
                dataGridView2.Rows[dataGridRow].Cells["colMbrSep"].Value = resultsDT.Rows[currentRow]["MBRSEP"];
                dataGridView2.Rows[dataGridRow].Cells["colLocation"].Value = resultsDT.Rows[currentRow]["LOCATION"];
                dataGridView2.Rows[dataGridRow].Cells["colDistrict"].Value = resultsDT.Rows[currentRow]["DIST"];
                dataGridView2.Rows[dataGridRow].Cells["colAddress"].Value = resultsDT.Rows[currentRow]["ADDR1"];
                dataGridView2.Rows[dataGridRow].Cells["colMeter"].Value = resultsDT.Rows[currentRow]["METER"];
                dataGridView2.Rows[dataGridRow].Cells["colKWh"].Value = resultsDT.Rows[currentRow]["KWH"];
                dataGridRow++;
            }
            currentRow++;
        }
