Fastest Convert from Collection to List<T>

Question

What I'd like to avoid:

ManagementClass m = new ManagementClass("Win32_LogicalDisk");  ManagementObjectCollection managementObjects = m.GetInstances();  List<ManagementObject> managementList = new List<ManagementObject>();  foreach(ManagementObject m in managementObjects){      managementList.Add(m);  } 

Isn't there a way to get that collection into a List that looks something like:

List<ManagementObject> managementList = new List<ManagementObjec>(collection_array); 

Answer 1

What version of the framework? With 3.5 you could presumably use:

List<ManagementObject> managementList = managementObjects.Cast<ManagementObject>().ToList(); 

(edited to remove simpler version; I checked and ManagementObjectCollection only implements the non-generic IEnumerable form)

Answer 2

You could use

using System.Linq; 

That will give you a ToList<> extension method for ICollection<>
