如何在C#中为一维数组中指定位置的元素设置值

2024-05-01 17:48:03 364

首先，设置数组-

int[] p = new int[] {55, 66, 88, 99, 111, 122, 133};

现在，让我们说您需要在位置1处设置一个元素-

p[2] = 77;

让我们看看编译代码-

示例

using System;

namespace Program {
   public class Demo {
      public static void Main(string[] args) {
         int[] p = new int[] {55, 66, 88, 99, 111, 122, 133};
         int j;

         Console.WriteLine("Initial Array......");
         for (j = 0; j < p.Length; j++ ) {
            Console.WriteLine("arr[j] = {0}", p[j]);
         }
         //在索引2处设置新元素
         p[2] = 77;

         Console.WriteLine("New Array......");
         for (j = 0; j < p.Length; j++ ) {
            Console.WriteLine("arr[j] = {0}", p[j]);
         }
      }
   }
}

输出结果

Initial Array......
arr[j] = 55
arr[j] = 66
arr[j] = 88
arr[j] = 99
arr[j] = 111
arr[j] = 122
arr[j] = 133
New Array......
arr[j] = 55
arr[j] = 66
arr[j] = 77
arr[j] = 99
arr[j] = 111
arr[j] = 122
arr[j] = 133
