循环2个特定列并执行计算计数器，输入到另一个datagridview中

// 获取第一个DataGridView中的两个特定列的数据
List<int> column1Data = new List<int>();
List<int> column2Data = new List<int>();

foreach (DataGridViewRow row in dataGridView1.Rows)
{
    int column1Value = Convert.ToInt32(row.Cells["Column1"].Value);
    int column2Value = Convert.ToInt32(row.Cells["Column2"].Value);

    column1Data.Add(column1Value);
    column2Data.Add(column2Value);
}

// 执行计算操作并将结果添加到新的数据结构中
List<int> calculationResults = new List<int>();

for (int i = 0; i < column1Data.Count; i++)
{
    int result = column1Data[i] + column2Data[i];
    calculationResults.Add(result);
}

// 将计算结果绑定到第二个DataGridView中
dataGridView2.DataSource = calculationResults;
