调用getRandomIp()方法即可
Framework3.5 +使用LINQ
public string getRandomIp()
{ /*
int[][]
这个叫交错数组,白话文就是数组的数组.
初始化的方法:
int[][] numbers = new int[][] { new int[] {2,3,4}, new int[] {5,6,7,8,9} };
当然也可以使用{}初始化器初始化
int[][] numbers = { new int[] {2,3,4},
new int[] {5,6,7,8,9}
};

加了比较不容易理解部分的注释..想弄明白的同学想必现在已经明白了吧
