转换枚举类到集合，用于绑定到控件

protected IDictionary<int, string> GetAll<TEnum>() where TEnum : struct
    {
        var enumerationType = typeof(TEnum);

        if (!enumerationType.IsEnum)
            throw new ArgumentException("Enumeration type is expected.");

        var dictionary = new Dictionary<int, string>();

        foreach (int value in Enum.GetValues(enumerationType))
        {
            var name = Enum.GetName(enumerationType, value);
            dictionary.Add(value, name);
        }

        return dictionary;
    }
