using System.Collections.Generic // You need to include this!
// 1º Method
var myList = new List<int>();
//OR
List<int> myList = new List<int>();
// 2º Method
List<int> myList = new List<int>() {2, 5, 9, 12};
// 3º Method
string myString = "Hello"
List<char> myList = new List<char>(myString); // Creates a list of characters from that string
//OR
var myFirstList = new List<int>() {9, 2, 4, 3, 2, 1};
var mySecondList = new List<int>(myFirstList); // Copy a list to a second list
// -------- How to dynamically change the List of elements? --------- //
// Use the Add or Insert method to add one element
myList.Add(4);
myList.Insert(0,3) // Insert element "3" in position "0"
// Use the AddRange method to add many elements (you can use an array or
// list, for passing the values)
myList.AddRange(new int[3] {3, 5, 5, 9, 2});
// Use the Remove method to eliminate specific elements
for (int i = 0; i < myList.Count; i++) // Use a for loop to remove
{ // repeated elements
if ( myList[i] == 5)
{
myList.Remove(myList[i]);
i--;
}
}
// Use the Clear method to remove all elements from the list
myList.Clear();
