C# Params
There are cases when we don’t know the actual number of parameters in the function call. Well, in C# we can pass any number of parameters in the function call by using params prior to the formal parameters in function definition. It is a keyword which is used to specify a parameter which can take unknown number of arguments. Only params is allowed and no extra arguments can be passed.
C# Params Example:
using System;
public class ArrayExample
{
void showValues(params int[] val)
{
foreach(int i in val)
{
Console.WriteLine(i);
}
}
public static void Main (string[] args)
{
ArrayExample a1=new ArrayExample();
a1.showValues(1,2,3,4,5,6,7,8,9,10);
}
}
Output
1 2 3 4 5 6 7 8 9 10C# Params Example 2: passing unknown number of objects to the function
using System;
public class ArrayExample
{
void showValues(params object[] val)
{
foreach(object i in val)
{
Console.WriteLine(i);
}
}
public static void Main (string[] args)
{
ArrayExample a1=new ArrayExample();
a1.showValues("Ram",21,"B. Tech.");
}
}
Output :
Ram 21 B. Tech.
