C#中泛型容器Stack<T>

　　　　我以前都是学出c，c++，这个学期开始学c#有点不适应，在编程中遇到些问题，所以自己在网上查了些资料，翻了一下书，写一些总结。

　　　　关于c#中Stack<T>泛型容器：

　　　　《1》stack，是一种数据结构——栈，是一种操作受到限制的线性表，只能在一端插入和删除，FILO（first input Last Output)或LIFO(last input first Output)

　　　　　　我们不用去管它在编译器中是采用什么样的存储结构。

　　　　

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);
}
}
