Function Parameters
When a function is to accept parameters, you must specify the following: A list of the parameters accepted by the function in its definition, along with the types of those parameters .
A matching list of parameters in each function call . This involves the following code, where you can have any number of parameters, each with a type and
a name:
static < returnType > < functionName > ( < paramType > < paramName > , …)
{
…
return < returnValue > ;
}
The parameters are separated using commas, and each of these parameters is accessible from code within the function as a variable. For example, a simple function might take two double parameters and return their product:
static double Product(double param1, double param2)
{
return param1 * param2;
}
Example
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
static int MaxValue(int[] intArray)
{
int maxVal = intArray[0];
for (int i = 1; i < intArray.Length; i++)
{
if (intArray[i] > maxVal)
maxVal = intArray[i];
}
return maxVal;
}
static void Main(string[] args)
{
int[] myArray = { 1, 8, 3, 6, 2, 5, 9, 3, 0, 2 };
int maxVal = MaxValue(myArray);
Console.WriteLine("The maximum value in myArray is {0}", maxVal);
Console.ReadKey();
}
}
}
