我们如何在 C# 方法中传递数组?
将数组作为方法参数传递给方法。
假设以下为我们的数组声明和初始化。
MyArray app = new MyArray(); /* an int array with 5 elements */ int [] balance = new int[]{1000, 2, 3, 17, 50};
现在调用方法 getAverage(),并将数组作为方法参数传递。
double getAverage(int[] arr, int size) { // code }
以下示例展示如何在 C# 方法中传递数组。
示例
using System; namespace ArrayApplication { class MyArray { double getAverage(int[] arr, int size) { int i; double avg; int sum = 0; for (i = 0; i < size; ++i) { sum += arr[i]; } avg = (double)sum / size; return avg; } static void Main(string[] args) { MyArray app = new MyArray(); /* an int array with 5 elements */ int [] balance = new int[]{1000, 2, 3, 17, 50}; double avg; /* pass pointer to the array as an argument */ avg = app.getAverage(balance, 5 ) ; /* output the returned value */ Console.WriteLine( "Average value is: {0} ", avg ); Console.ReadKey(); } } }
输出
Average value is: 214.4
