In this chapter, we will discuss in C# Passing Arrays as Function Arguments. You can pass an array as a function argument in C#. The following example demonstrates this −
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();
}
}
}
When the above code is compiled and executed, it produces the following result −
Average value is: 214.4
