C# – Populate list from array

arraysc++generics

if i have an array. can i populate a generic list from that array:

Foo[] fooList . . . (assume populated array)

// This doesn't seem to work
List<Foo> newList = new List<Foo>(fooList);

You could convert the array to a List:

string[] strings = { "hello", "world" };
IList<string> stringList = strings.ToList();

new ArrayList<>(Arrays.asList(array));

Modern browsers have Array#includes, which does exactly that and is widely supported by everyone except IE:

console.log(['joe', 'jane', 'mary'].includes('jane')); //true

You can also use Array#indexOf, which is less direct, but doesn't require polyfills for outdated browsers.

console.log(['joe', 'jane', 'mary'].indexOf('jane') >= 0); //true

Many frameworks also offer similar methods:

Notice that some frameworks implement this as a function, while others add the function to the array prototype.
