c# getting a list from a field out of a list

I'm sorry about the confusing title, but I didnt find a better way to explain my issue.

I have a list of objects, myList, lets call them MyObject. the objects look something like this:

Class MyObject
{
    int MYInt{get;set;}
    string MYString{get;set;}
}

List<MyObject> myList;
...

I am开发者_如何学编程 looking for a nice/short/fancy way to create a List<string> from myList, where I am using only the MyString property.

I can do this using myList.forEach(), but I was wondering if there's a nicer way

Thanks!!

With LINQ:

var list = myList.Select(o => o.MYString);

That returns an IEnumerable<string>. To get a List<string> simply add a call to ToList():

var list = myList.Select(o => o.MYString).ToList();

Then iterate over the results as you normally would:

foreach (string s in list)
{
    Console.WriteLine(s);
}

There's no need for LINQ if your input and output lists are both List<T>. You can use the ConvertAll method instead:

List<string> listOfStrings = myList.ConvertAll(o => o.MYString);

Here's Ahmad's answer using integrated query syntax:

var strings = from x in myList
              select x.MYString;

List<string> list = strings.ToList();

This could also be written:

List<string> list = (from x in myList
                     select x.MYString).ToList();
