C# 中数组的好例子有哪些？

数组用于存储一组数据。它由连续的内存位置组成。

一些数组的示例包括 −

在三个已排序的数组中查找公共元素

using System;

class Demo {

static void commonElements(int []one, int []two, int []three) {
int i = 0, j = 0, k = 0;

while (i < one.Length && j < two.Length && k < three.Length) {
if (one[i] == two[j] && two[j] == three[k]) {
Console.Write(one[i] + " ");
i++;j++;k++;
}

else if (one[i] < two[j])
i++;

else if (two[j] < three[k])
j++;

else
k++;
}
}

public static void Main() {
int []one = {20, 35, 57, 70};
int []two = {9, 35, 57, 70, 92};
int []three = {25, 35, 55, 57, 67, 70};

Console.Write("Common elements: ");

commonElements(one, two, three);
}
}

在C#中动态创建数组

using System;
using System.Collections;

namespace CollectionApplication {
class Program {
static void Main(string[] args) {
ArrayList al = new ArrayList();

al.Add(99);
al.Add(47);
al.Add(64);

Console.WriteLine("Count: {0}", al.Count);

Console.Write("List: ");
foreach (int i in al) {
Console.Write(i + " ");
}

Console.WriteLine();

Console.ReadKey();
}
}
}

使用C#处理不规则数组并访问元素

using System;

namespace ArrayApplication {
class MyArray {
static void Main(string[] args) {

int[][] points = new int[][]{new int[]{10,5},new int[]{30,40}, new int[]{70,80},new int[]{ 60, 70 }};
int i, j;

for (i = 0; i < 3; i++) {
for (j = 0; j < 2; j++) {
Console.WriteLine("a[{0}][{1}] = {2}", i, j, points[i][j]);
}
}

// access
int x = points[0][1];
Console.WriteLine(x);
Console.ReadKey();
}
}
}
