示例1: Number
//引入命名空间
using System;
public struct Number
{
private int n;
public Number(int value)
{
n = value;
}
public int Value
{
get { return n; }
}
public override bool Equals(Object obj)
{
if (obj == null || ! (obj is Number))
return false;
else
return n == ((Number) obj).n;
}
public override int GetHashCode()
{
return n;
}
public override string ToString()
{
return n.ToString();
}
}
public class Example
{
public static void Main()
{
Random rnd = new Random();
for (int ctr = 0; ctr <= 9; ctr++) {
int randomN = rnd.Next(Int32.MinValue, Int32.MaxValue);
Number n = new Number(randomN);
Console.WriteLine("n = {0,12}, hash code = {1,12}", n, n.GetHashCode());
}
}
}
