示例1: Main
//引入命名空间
using System;
using System.Collections.Generic;
class Example
{
public static void Main()
{
Stack<string> numbers = new Stack<string>();
numbers.Push("one");
numbers.Push("two");
numbers.Push("three");
numbers.Push("four");
numbers.Push("five");
// A stack can be enumerated without disturbing its contents.
foreach( string number in numbers )
{
Console.WriteLine(number);
}
Console.WriteLine("\nPopping '{0}'", numbers.Pop());
Console.WriteLine("Peek at next item to destack: {0}",
numbers.Peek());
Console.WriteLine("Popping '{0}'", numbers.Pop());
// Create a copy of the stack, using the ToArray method and the
// constructor that accepts an IEnumerable<T>.
Stack<string> stack2 = new Stack<string>(numbers.ToArray());
Console.WriteLine("\nContents of the first copy:");
foreach( string number in stack2 )
{
Console.WriteLine(number);
}
// Create an array twice the size of the stack and copy the
// elements of the stack, starting at the middle of the
// array.
string[] array2 = new string[numbers.Count * 2];
numbers.CopyTo(array2, numbers.Count);
// Create a second stack, using the constructor that accepts an
// IEnumerable(Of T).
Stack<string> stack3 = new Stack<string>(array2);
Console.WriteLine("\nContents of the second copy, with duplicates and nulls:");
foreach( string number in stack3 )
{
Console.WriteLine(number);
}
Console.WriteLine("\nstack2.Contains(\"four\") = {0}",
stack2.Contains("four"));
Console.WriteLine("\nstack2.Clear()");
stack2.Clear();
Console.WriteLine("\nstack2.Count = {0}", stack2.Count);
}
}输出：
five
four
three
two
one
Popping 'five'
Peek at next item to destack: four
Popping 'four'
Contents of the first copy:
one
two
three
Contents of the second copy, with duplicates and nulls:
one
two
three
stack2.Contains("four") = False
stack2.Clear()
stack2.Count = 0
