说明: 下面的程序是求多项式y=x^6-10x^5-26x^4+344x^3+193x^2-1846x-1680在区间[-8,8]的最小值,误差不超过0.001。对于这个复杂的多项式,可先用matlab绘制函数的大概曲线,确认函数的最小值大概处于[-8,8]之间,再用本程序求出精确解。 (The following procedure is a polynomial y = x ^ 6-10x ^ 5-26x ^ 4+344 x ^ 3+193 x ^ 2-1846x-1680 in the interval [-8,8] of the minimum error is not more than 0.001. This is a complex polynomial, can first draw function with matlab about curves, to confirm the function of the minimum are probably in [-8,8] range, and then find the exact solution of this program.)

C# 显示DataGridView控件中选定的单元格、行和列
Visual C#显示选择的DataGridView单元格,获取DataGridView控件中选定的单元格、行和列,测试前请连接好数据库,实现此功能核心代码如下:
if (customersDataGridView.AreAllCellsSelected(true))
{
MessageBox.Show("所有单元格已经被选择!", "信息提示",MessageBoxButtons.OK);
}
else
{
System.Text.StringBuilder MyInfo =new System.Text.StringBuilder();
for (int i = 0;
i < MyCount; i++)
{
MyInfo.Append("行号: ");
MyInfo.Append(customersDataGridView.SelectedCells[i].RowIndex.ToString());
MyInfo.Append(", 列号: ");
MyInfo.Append(customersDataGridView.SelectedCells[i].ColumnIndex.ToString());
MyInfo.Append(", 单元格值: ");
MyInfo.Append(customersDataGridView.SelectedCells[i].Value.ToString());
MyInfo.Append(Environment.NewLine);
}
MyInfo.Append("一共选择了: " + MyCount.ToString()+"个单元格");
MessageBox.Show(MyInfo.ToString(), "信息提示", MessageBoxButtons.OK);
}
