c#2.0泛型学习(一)

根据微软的视频教程"跟我一起学Visual Studio 2005C#语法篇"来学,因为里面有比较多的代码示例,学起来比较容易好理解

1.未使用泛型的Stack类

 1using System;
 2
 3public class Stack
 4{
 5    readonly int m_Size;
 6    int m_StackPointer = 0;
 7    object[] m_Items;
 8    public Stack(): this(100)
 9    { }
10    public Stack(int size)
11    {
12        m_Size = size;
13        m_Items = new object[m_Size];
14    }
15    public void Push(object item)
16    {
17        if (m_StackPointer >= m_Size)
18            throw new StackOverflowException();
19
20        m_Items[m_StackPointer] = item;
21        m_StackPointer++;
22    }
23    public object Pop()
24    {
25        m_StackPointer--;
26        if (m_StackPointer >= 0)
27        {
28            return m_Items[m_StackPointer];
29        }
30        else
31        {
32            m_StackPointer = 0;
33            throw new InvalidOperationException("Cannot pop an empty stack");
34        }
35    }
36}

2.使用泛型的类

 1using System;
 2
 3public class Stack<T>
 4{
 5    readonly int m_Size;
 6    int m_StackPointer = 0;
 7    T[] m_Items;
 8    public Stack()
 9        : this(100)
10    {
11    }
12    public Stack(int size)
13    {
14        m_Size = size;
15        m_Items = new T[m_Size];
16    }
17    public void Push(T item)
18    {
19        if (m_StackPointer >= m_Size)
20            throw new StackOverflowException();
21
22        m_Items[m_StackPointer] = item;
23        m_StackPointer++;
24    }
25    public T Pop()
26    {
27        m_StackPointer--;
28        if (m_StackPointer >= 0)
