How do I copy items from list to list without foreach?

Question

How do I transfer the items contained in one List to another in C# without using foreach?

Answer 1

OK this is working well From the suggestions above GetRange( ) does not work for me with a list as an argument...so sweetening things up a bit from posts above: ( thanks everyone :)

/*  Where __strBuf is a string list used as a dumping ground for data  */
public List < string > pullStrLst( )
{
    List < string > lst;

    lst = __strBuf.GetRange( 0, __strBuf.Count );     

    __strBuf.Clear( );

    return( lst );
}

Answer 2

Here another method but it is little worse compare to other.

List<int> i=original.Take(original.count).ToList();

Answer 3

And this is if copying a single property to another list is needed:

targetList.AddRange(sourceList.Select(i => i.NeededProperty));

Answer 4

To add the contents of one list to another list which already exists, you can use:

targetList.AddRange(sourceList);

If you're just wanting to create a new copy of the list, see Lasse's answer.

Answer 5

You could try this:

List<Int32> copy = new List<Int32>(original);

or if you're using C# 3 and .NET 3.5, with Linq, you can do this:

List<Int32> copy = original.ToList();

Answer 6

This method will create a copy of your list but your type should be serializable.

Use:

List<Student> lstStudent = db.Students.Where(s => s.DOB < DateTime.Now).ToList().CopyList(); 

Method:

public static List<T> CopyList<T>(this List<T> lst)
    {
        List<T> lstCopy = new List<T>();
        foreach (var item in lst)
        {
            using (MemoryStream stream = new MemoryStream())
            {
                BinaryFormatter formatter = new BinaryFormatter();
                formatter.Serialize(stream, item);
                stream.Position = 0;
                lstCopy.Add((T)formatter.Deserialize(stream));
            }
        }
        return lstCopy;
    }
