Convert ICollection<T> to List<T>

Question

I am trying to convert ICollection to List using below code-

ICollection<DataStructure> list_Stuctures = dataConnectorService.ListStructures(dataConnector, SupportedDataStructures.All);  List<DataStructure> lst_DataStructure = new List<DataStructure>();  list_Stuctures.CopyTo(lst_DataStructure); 

On last line, I get below exception-

Exception = TargetParameterCountException

Message = Parameter count mismatch.

How to convert ICollection to List?

Answer 1

The easiest way to convert a ICollection to a List is the usage of LINQ like (MSDN)

List<T> L = C.ToList(); 

Dont't forget to add

using System.Linq; 

otherwise ToList() is not available.
