C #: Is it possible to assign an implicit Arraylist?

Question

I would like to populate the arraylist by specifying a list of values ​​just like I would an integer array, but I'm not sure how to do this without calling the add method again.

For example, I want to assign {1, 2, 3, "string1", "string2"} to arraylist. I know that for other arrays you can do the job as follows:

int[] IntArray = {1,2,3};

Is there a similar way to do this for an arraylist? I tried the addrange method, but the curly brace method does not implement the ICollection interface.

Answer 1

There is a ctor in the list of arrays that accepts an ICollection, which is implemented by the Array class.

object[] myArray = new object[] {1,2,3,"string1","string2"};
ArrayList myArrayList = new ArrayList(myArray);

List<int> list = new List<int>{1,2,3};

List<int> list = new List<int>(new int[] {1, 2, 3});

ArrayList list = new ArrayList(new object[] { 1, 2, 3, "string1", "string2"});

Answer 5

( , ...)

The closest I found to what I want is to use the ArrayList.Adapter method:

object[] values = { 1, 2, 3, "string1", "string2" };
ArrayList AL = new ArrayList();
AL = ArrayList.Adapter(values);

//or during intialization
ArrayList AL2 = ArrayList.Adapter(values);

This is enough for what I need, but I was hoping it could be done on one line without creating a temporary array, as someone else had suggested.
