How to convert a list of string to a list of a class in C#?

I have a list of string like this :

public List<string> Subs { get; set; }

and I have a list<Category> Cat { get; set; } of this class :

public class Category
    {
        public int ID { get; set; }

        public string Name { get; set; }

        public int SubCat_ID { get; set; }
    }

I just need to put all of the values in the list<string> Subs into the List<Category> Cat. and of course each string in the list<string> should be placed in each Name parameter of List<Category>.

So how is it done ? Is there any convert method which does the thing? how does it work ?

Thanks in advance ;)

In case both lists exist, Zip should be used:

 var result = categories.Zip(subs, (cate, sub) =>
            {
                cate.Name = sub;
                return cate;
            });

You can use the ConvertAll method of the List class:

Cat = Subs.ConvertAll(s => new Category { Name = s });

Use the "Select" enumerable extension method:

followed by a "ToList()" like this:

var newList = Subs.Select(name => new Category { Name = name}).ToList();

You have to make a function manually, otherwise it would be very hard for the program to understand what property should correspond to the string in the list.

Yes, you can do it with LINQ:

var cats = (from sub in Subs
            select new Category
            {
                Name = sub
            }).ToList();
