c#2.0泛型学习(一) _C#教程

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}

37

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)
