I have a List containing several objects. Is there any way I can print out just one of the objects?

Console.WriteLine(myList.ElementAt(1));

This line of code does not give me the object. It does however give me the name of the Class.

    You need to print out the object properties one by one. Like `Console.WriteLine(myList.ElementAt(1).Name);` for example. Or override the `ToString` method, but that's usually not the right solution. – DavidG Nov 27 '19 at 12:29

    You have to override the .ToString(). For your object. Then you can say myList.ElementAt(1).ToString() – panoskarajohn Nov 27 '19 at 12:30
  • By default, [`ToString`](https://learn.microsoft.com/en-us/dotnet/api/system.object.tostring?view=netframework-4.8) returns a fully-qualified name of the type. If you need to display something different (some of the properties e.g. name) you need to override it. If you need a generic method to print all of the object properties to console, see this question: https://stackoverflow.com/questions/852181/c-printing-all-properties-of-an-object – default locale Nov 27 '19 at 12:36

You have two ways.

  1. Access the properties separately

    var element = myList.ElementAt(1);
Console.WriteLine("ID:{0}, Name:{1}", element.ID, element.Name);

  1. or overload the ToString() for the class

    public class myObject
{
    public int ID { get; set; }
    public string Name { get; set; }

    public override string ToString()
    {
        return string.Format("ID:{0}, Name:{1}", ID, Name);
    }
}

    so you can

    Console.WriteLine(myList.ElementAt(1));

  • @Frauke I tried to, but it wouldn't let me at the time. Just came back to my computer. Answer is accepted! :) – John Carlson Nov 27 '19 at 13:51
