在c# 中怎样用reverse和sort来实现数组的降序排列？

网上抄的：

在 .NET Framework 中，数组是作为 Array 类的实例实现的。此类提供了许多有用的方法，如 Sort 和 Reverse。

下面的示例演示了使用这些方法是多么的简单。首先，使用 Reverse 方法将数组元素反转，然后使用 Sort 方法对它们进行排序：

C#
class ArrayMethods
{
static void Main()
{
// Create a string array of size 5:
string[] employeeNames = new string[5];

// Read 5 employee names from user:
System.Console.WriteLine("Enter five employee names:");
for(int i=0; i {
employeeNames[i]= System.Console.ReadLine();
}

// Print the array in original order:
System.Console.WriteLine("\nArray in Original Order:");
foreach(string employeeName in employeeNames)
{
System.Console.Write("{0} ", employeeName);
}

// Reverse the array:
System.Array.Reverse(employeeNames);

// Print the array in reverse order:
System.Console.WriteLine("\n\nArray in Reverse Order:");
foreach(string employeeName in employeeNames)
{
System.Console.Write("{0} ", employeeName);
}

// Sort the array:
System.Array.Sort(employeeNames);

// Print the array in sorted order:
System.Console.WriteLine("\n\nArray in Sorted Order:");
foreach(string employeeName in employeeNames)
{
System.Console.Write("{0} ", employeeName);
}
}
}

输出
Enter five employee names:

Luca

Angie

Brian

Kent

Beatriz

Array in Original Order:

Luca Angie Brian Kent Beatriz

Array in Reverse Order:

Beatriz Kent Brian Angie Luca

Array in Sorted Order:

Angie Beatriz Brian Kent Luca
