这是示例代码:

static class Store
{
    private static List<String> strList = new List<string>();
    private static HashSet<String> strHashSet = new HashSet<string>();

    public static List<String> NormalList
    {
        get { return strList; }
    }

    public static HashSet<String> NormalHashSet
    {
        get { return strHashSet; }
    }

    public static IReadOnlyList<String> ReadonlyList
    {
        get { return (IReadOnlyList<String>)strList; }
    }

    public static IReadOnlyCollection<String> ReadonlyHashSet
    {
        get { return (IReadOnlyCollection<String>)strHashSet; }
    }

    public static IReadOnlyList<String> Real_ReadonlyList
    {
        get { return (IReadOnlyList<String>)strList.AsReadOnly(); }
    }

    public static IReadOnlyCollection<String> Real_ReadonlyHashSet
    {
        get …
