以当前显示的顺序获取选定的DataGridViewRows

// 获取选定行集合
DataGridViewSelectedRowCollection selectedRows = dataGridView1.SelectedRows;

// 获取当前排序的列
DataGridViewColumn sortedColumn = dataGridView1.SortedColumn;

// 获取当前排序的顺序
SortOrder sortOrder = dataGridView1.SortOrder;

// 如果有排序列，则根据排序顺序对选定行进行排序
if (sortedColumn != null)
{
    // 根据排序顺序对选定行进行排序
    if (sortOrder == SortOrder.Ascending)
    {
        selectedRows.Sort(new RowComparer(SortOrder.Ascending));
    }
    else if (sortOrder == SortOrder.Descending)
    {
        selectedRows.Sort(new RowComparer(SortOrder.Descending));
    }
}

// 遍历排序后的选定行集合，按照顺序获取选定的DataGridViewRows
foreach (DataGridViewRow row in selectedRows)
{
    // 处理选定行的逻辑
    // ...
}

// 自定义行比较器，用于排序选定行
