代码重复率高，求优化代码

[jackylynn]

我想做一个彩票的走势分析图，控件是datagridview，如果哪个号中了就把单元格变成红色，如果哪个号经过修改之后要变成白色。系统用3层架构做的，其实这个小系统不用如此费尽，只是我现在正在学习想练一练。数据库表的字段是期数，1，2，3，4，5，6

现在功能已经实现了，但感觉代码重复率很高，不干净，求优化，代码如下：

//j控制行数
for (int j = 0; j < lotterys.Count; j++)
{
dgvNumCount.Rows.Add();
//赋值期数
dgvNumCount.Rows[j].Height = 20;
dgvNumCount.Rows[j].Cells[0].Value = lotterys[j].Period;

//赋值红球，K代表列
for (int k = 1; k < 34; k++)
{
if (lotterys[j].One.Equals(int.Parse(dgvNumCount.Columns[k].HeaderText.Trim())))
{
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.Red;
continue;
}
if (lotterys[j].Two.Equals(int.Parse(dgvNumCount.Columns[k].HeaderText.Trim())))
{
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.Red;
continue;
}
if (lotterys[j].Three.Equals(int.Parse(dgvNumCount.Columns[k].HeaderText.Trim())))
{
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.Red;
continue;
}
if (lotterys[j].Four.Equals(int.Parse(dgvNumCount.Columns[k].HeaderText.Trim())))
{
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.Red;
continue;
}
if (lotterys[j].Five.Equals(int.Parse(dgvNumCount.Columns[k].HeaderText.Trim())))
{
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.Red;
continue;
}
if (lotterys[j].Six.Equals(int.Parse(dgvNumCount.Columns[k].HeaderText.Trim())))
{
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.Red;
continue;
}

if (lotterys[j].One != int.Parse(dgvNumCount.Columns[k].HeaderText.Trim()))
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.White;

if (lotterys[j].Two != int.Parse(dgvNumCount.Columns[k].HeaderText.Trim()))
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.White;

if (lotterys[j].Three != int.Parse(dgvNumCount.Columns[k].HeaderText.Trim()))
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.White;

if (lotterys[j].Four != int.Parse(dgvNumCount.Columns[k].HeaderText.Trim()))
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.White;

if (lotterys[j].Five != int.Parse(dgvNumCount.Columns[k].HeaderText.Trim()))
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.White;

if (lotterys[j].Six != int.Parse(dgvNumCount.Columns[k].HeaderText.Trim()))
dgvNumCount.Rows[j].Cells[k].Style.BackColor = Color.White;

}
}

传说是可以的.
你可以说明下你的代码吗???
lotterys 是什么....
