Add string items from array to a list of object

Question

I have an array of string defined as follows:

string[] items = { "Item 1", "Item 2", "Item 3", "Item 4"};

Then I have a model defined as :

public class ItemModel {

        public int Id { get; set; }

        public string ItemName { get; set; }

        public bool IsItem { get; set; }
}

I have defined a list as :

var listItems = new List<ItemModel>();

I want to add the items from the array items to the list of object of listItems. I want to add the items to ItemName

while adding to List<ItemModel> whats the Id and IsItem for respective item? — er-sho

This can be achieved using a very simple Linq:

listItems  = items.Select(i => new ItemModel { ItemName = i}).ToList();

@AshkanMobayenKhiabani Its recommended not to answer duplicates though. You have to make people search a bit (or direct them to the correct answer by marking as duplicate)

@EpicKip you are absolutely right, but when I saw the question, I didn't search it, I knew the answer, so I answered.

You could either use Select as:

  var result = items.Select(i => new ItemModel {ItemName = i}).ToList()

Or:

foreach(var item in items)
{
    listItems.Add(new ItemModel{ItemName = item});
}

You can try this:

    listItems = items.Select(i => new ItemModel { Id = Array.IndexOf(items, i), ItemName = i, IsItem = true }).ToList();
