如何有效地从IReadOnlyCollection获取列表形式的属性？

using System.Collections.Generic;

public class MyClass
{
    public IReadOnlyCollection<int> MyProperty { get; set; }
}

public class Program
{
    public static void Main()
    {
        MyClass myObject = new MyClass();
        myObject.MyProperty = new List<int> { 1, 2, 3, 4, 5 };

        List<int> myList = new List<int>();
        myList.AddRange(myObject.MyProperty.ToList());

        // 现在，myList包含了从IReadOnlyCollection获取的列表形式的属性
    }
}
