Convert string array to custom object list using linq

Question

I have a class with one public property.

public class CustomEntity 
{
    string _FileName;
    public string FileName
    {
        get { return _FileName; }
        set
        {                    
           _FileName = value;

        }
    }

}

I have array of string which I want to convert in List of "CustomEntity" using linq. please suggest me how I can do that.

Well, how much research have you done? What's the purpose of your Instance property (which confusingly will return a new instance on each call)? Note that not having an accessible constructor will mean you can't use object initializers. — Jon Skeet

You can do it exactly how you said, using LINQ. Everything you need can be found with some effort on your side. We won't code it for you. See this: msdn.microsoft.com/en-us/library/bb397933.aspx — tnw

I would use Linq's Select extension and ToList to convert the IEnumerable (from Select extension) to a list

An Example:

string[] randomArray = new string[3] {"1", "2", "3"};
List<CustomEntity> listOfEntities = randomArray.Select(item => new CustomEntity() { FileName = item } ).ToList();

wouldn't it be sufficient enough to use just: List<CustomEntity> = randomArray.ToList()
