The

The "params" keyword for method allows you specify a method parameter that takes an argument where the number of arguments is variable.

No additional parameters are permitted after the "params" keyword in a method declaration, and only one "params" keyword is permitted in a method declaration.

using System;
//method_param.cs
public class team
{

public static void bdale(string a, params object[] list)
{
Console.WriteLine("team : " + a);
for ( int i = 0 ; i < list.Length ; i++ )

Console.Write(list[i]);
Console.WriteLine();

}
public static void raiders(string b, params object[] list)
{
Console.WriteLine("team : " +b);
for ( int i = 0 ; i < list.Length ; i++ )

Console.Write(list[i]);
Console.WriteLine();
}
}
class test
{
public static void Main()
{

team.bdale("bdale","Baba #", 10, " Position Defense");
Console.WriteLine("---------------");
team.raiders("raiders","Jacob #", 7 , " Position Offense");
}
}

while calling you need to call with the class, not with the objects. if you write like this

team A =new Team();
A.bdale("bdale","Baba #", 10, " Position Defense");
This will not compile
