how to use "methods" in object list c# code example

Example 1: C# list

List<string> myListOfStrings = new List<string> 
{
	"this",
	"is",
	"my",
	"list"
};

Example 2: syntax list C#

List<int> primeNumbers = new List<int>();
primeNumbers.Add(1); // adding elements using add() method
primeNumbers.Add(3);
primeNumbers.Add(5);
primeNumbers.Add(7);

var cities = new List<string>();
cities.Add("New York");
cities.Add("London");
cities.Add("Mumbai");
cities.Add("Chicago");
cities.Add(null);// nulls are allowed for reference type list

//adding elements using collection-initializer syntax
var bigCities = new List<string>()
                    {
                        "New York",
                        "London",
                        "Mumbai",
                        "Chicago"                    
                    };
