首先，设置数组为 −
int[] p = new int[] {55, 66, 88, 99, 111, 122, 133};
现在，假设您需要将位置 1 的元素赋值 −
p[2] = 77;
我们来看看完整的代码 −
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]);
}
// set new element at index 2
p[2] = 77;
Console.WriteLine("New Array......");
for (j = 0; j < p.Length; j++ ) {
Console.WriteLine("arr[j] = {0}", p[j]);
}
}
}
}
输出
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
