Convert a list of objects to an array of one of the object's properties

Question

Say I have the following class:

public class ConfigItemType {     public string Name { get; set; }     public double SomeOtherThing { get; set; } } 

and then I make a list of the following classes (List<ConfigItemType> MyList)

Now I have a method with the following signature:

void AggregateValues(string someUnrelatedValue, params string[] listGoesHere) 

How can I fit MyList in to the listGoesHere using the value in ConfigItemType.Name as the params string array?

I am fairly sure that Linq can do this.... but MyList does not have a select method on it (which is what I would have used).

Answer 1

You are looking for

MyList.Select(x=>x.Name).ToArray(); 

Since Select is an Extension method make sure to add that namespace by adding a

using System.Linq

to your file - then it will show up with Intellisense.
