用对象列表中的参数填充列表 c#

Question

Good morning, I'm looking for a more efficient way to fill a list of any type with an object parameter.

Example (my class) :

public class Thème
{
    public string Thème_ { get; set; }
    public Liste[] Listes { get; set; }
}

My code that I currently have to do what I want to do:

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

        foreach(Thème thème in Data.Thèmes)
        {
            nomDesThèmesDisponible.Add(thème.Thème_);
        }

I think there's an easier way to do that (with linq?).

Thank you for offering me your solutions

Answer 1

You can do

nomDesThèmesDisponible.AddRange(Data.Thèmes.Select(t => t.Thème_));

or

nomDesThèmesDisponible = Data.Thèmes.Select(t => t.Thème_).ToList();

These ways not anymore efficient, just more concise.

Answer 2

List<string> nomDesThèmesDisponible = Data.Thèmes.Select (t => t.Thème_).ToList();
