How to initialize a list of strings (List) with many string values

Question

How is it possible to initialize (with a C# initializer) a list of strings? I have tried with the example below but it\'s not working.

List opt         


        

Answer 1

List<string> mylist = new List<string>(new string[] { "element1", "element2", "element3" });

Answer 2

You haven't really asked a question, but the code should be

List<string> optionList = new List<string> { "string1", "string2", ..., "stringN"}; 

i.e. no trailing () after the list.

Answer 3

List<string> animals= new List<string>();
animals.Add("dog");
animals.Add("tiger");

Answer 4

One really cool feature is that list initializer works just fine with custom classes too: you have just to implement the IEnumerable interface and have a method called Add.

So for example if you have a custom class like this:

class MyCustomCollection : System.Collections.IEnumerable
{
    List<string> _items = new List<string>();

    public void Add(string item)
    {
        _items.Add(item);
    }

    public IEnumerator GetEnumerator()
    {
        return _items.GetEnumerator();
    }
}

this will work:

var myTestCollection = new MyCustomCollection()
{
    "item1",
    "item2"
}

Answer 5

This is how you would do it.

List <string> list1 = new List <string>();

Do Not Forget to add

using System.Collections.Generic;

Answer 6

var animals = new List<string> { "bird", "dog" };
List<string> animals= new List<string> { "bird", "dog" };
