一、冒泡排序(Bubble) 

using System; 

namespace BubbleSorter 
{ 
public class BubbleSorter 
{ 
public void Sort(int[] list) 
{ 
int i,j,temp; 
bool done=false; 
j=1; 
while((j<list.Length)&&(!done)) 
{ 
done=true; 
for(i=0;i<list.Length-j;i++) 
{ 
if(list[i]>list[i+1]) 
{ 
done=false; 
temp=list[i]; 
list[i]=list[i+1]; 
list[i+1]=temp; 
} 
} 
j++; 
} 
} 
} 

public class MainClass 
{ 
public static void Main() 
{ 
int[] iArrary=new int[]{1,5,13,6,10,55,99,2,87,12,34,75,33,47}; 
BubbleSorter sh=new BubbleSorter(); 
sh.Sort(iArrary); 
for(int m=0;m<iArrary.Length;m++) 
Console.Write("{0} ",iArrary[m]); 
Console.WriteLine(); 
} 
} 
} 

二、选择排序(Selection) 

using System; 

namespace SelectionSorter 
{ 
public class SelectionSorter 
{ 
private int min; 
public void Sort(int [] list) 
{ 
for(int i=0;i<list.Length-1;i++) 
{ 
min=i; 
for(int j=i+1;j<list.Length;j++) 
{ 
if(list[j]<list[min]) 
min=j; 
} 
int t=list[min]; 
list[min]=list[i]; 
list[i]=t; 
} 
} 
} 

public class MainClass 
{ 
public static void Main() 
{ 
int[] iArrary = new int[]{1,5,3,6,10,55,9,2,87,12,34,75,33,47}; 
SelectionSorter ss=new SelectionSorter(); 
ss.Sort(iArrary); 
for (int m=0;m<iArrary.Length;m++) 
Console.Write("{0} ",iArrary[m]); 
Console.WriteLine(); 
} 
} 
} 

三、插入排序(InsertionSorter) 

using System; 

namespace InsertionSorter 
{ 
public class InsertionSorter 
{ 
public void Sort(int [] list) 
{ 
for(int i=1;i<list.Length;i++) 
{ 
int t=list[i]; 
int j=i; 
while((j>0)&&(list[j-1]>t)) 
{ 
list[j]=list[j-1]; 
--j; 
} 
list[j]=t; 
} 
} 
} 

public class MainClass 
{ 
public static void Main() 
{ 
int[] iArrary=new int[]{1,13,3,6,10,55,98,2,87,12,34,75,33,47}; 
InsertionSorter ii=new InsertionSorter(); 
ii.Sort(iArrary); 
for(int m=0;m<iArrary.Length;m++) 
Console.Write("{0}",iArrary[m]); 
Console.WriteLine(); 
} 
} 
} 

四、希尔排序(ShellSorter) 

using System; 

namespace ShellSorter 
{ 
public class ShellSorter 
{ 
public void Sort(int [] list) 
{ 
int inc; 
for(inc=1;inc<=list.Length/9;inc=3*inc+1); 
for(;inc>0;inc/=3) 
{ 
for(int i=inc+1;i<=list.Length;i+=inc) 
{ 
int t=list[i-1]; 
int j=i; 
while((j>inc)&&(list[j-inc-1]>t)) 
{ 
list[j-1]=list[j-inc-1]; 
j-=inc; 
} 
list[j-1]=t; 
} 
} 
} 
} 

public class MainClass 
{ 
public static void Main() 
{ 
int[] iArrary=new int[]{1,5,13,6,10,55,99,2,87,12,34,75,33,47}; 
ShellSorter sh=new ShellSorter(); 
sh.Sort(iArrary); 
for(int m=0;m<iArrary.Length;m++) 
Console.Write("{0} ",iArrary[m]); 
Console.WriteLine(); 
} 
} 
}
