Introduction
Can you write a method that does not care about arguments. I mean, can you pass an arbitrary number of arguments in that method? I suggest a C# keyword that does provide this type of facility, named "Params".
The "Params" keyword allows passing a variable number arguments to a function.
What does "Params" do?
Using "Params", the arguments passed to a method are changed by the compiler to elements in a temporary array, and this array is then used to retrieve the method. To better clarify my point; I am try to explain an example in my thoughts about "Params".
Suppose we have a "totalsal()" function that calculates the total salary of all the employees, no matter how many employee's salarys are passed.
Why we use "Params"
To explain this point, I will also use another example.
I think you have already heard of the string class. The concat method, in case you have not heard of it, I will explain in one line, "this is used to concatenate two or more strings into one".
For example
string a ="abc";
string b="xyz";
string.Concat (a,b);
This method does not care how many string agreements are passed for concatenation.
For the purposes of the example above, you can say you are designing a library for other programmers to widely use.
Example
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Params
{
class Program
{
static void Main(string[] args)
{
ADDParameters(1);
ADDParameters(1, 2, 3, 4, 5);
ADDParameters1("sha","rad");
ADDParameters1("How", " are", " you", " ?");
Console.ReadKey();
}
//for interger calculation
public static void ADDParameters(params int[] arguemnts)
{
int add=0;
foreach (int argu in arguemnts)
{
add += argu;
}
Console.WriteLine(add);
}
public static void ADDParameters1(params string[] arguemnts)
{
string add="";
foreach (string argu in arguemnts)
{
add += argu;
}
Console.WriteLine(add);
}
}
}
