{
Console.WriteLine("请输入6个数字");
int[] nums = new int[6];
for (int i = 0; i < nums.Length; i++)
{
Console.WriteLine("请输入第{0}个数字:", i + 1);

}
for (int i = 0; i < nums.Length - 1; i++)
{
for (int j = 0; j < nums.Length - 1 - i; j++)
{
if (nums[j] < nums[j+1])
{
int temp = nums[j];
nums[j] = nums[j + 1];
nums[j + 1] = temp;
}
}
}
Console.Write("排序后的数字为：");
foreach (double var in nums
{
Console.Write(var);
Console.Write(" ");
}
}
catch
{
Console.WriteLine("你输入的格式有误");

Console.ReadKey();

二、
try
{
Console.WriteLine("请输入会员本月的消费记录");
double[] mon = new double [5];
double sum = 0;
for (int i = 0; i < mon.Length; i++)
{
Console.WriteLine("");
Console.WriteLine("请输入第{0}笔消费金额:", i + 1);
mon[i] = Convert.ToDouble(Console.ReadLine());
}
for (int i = 0; i<mon.Length;i++)
{
Console.WriteLine("序号\t\t\t金额(元)");
Console.WriteLine("{0}\t\t\t{1}",i+1,mon[i]);
sum += mon[i];
}
Console.WriteLine("总金额\t\t\t" +sum);
}
catch
{
Console.WriteLine("你输入的格式有误");
}
Console.ReadKey();
