public void 拷貝SafeDictionary_從Index0開始拷貝_拷貝的結果應該與SafeDictionary相同()
        {
            var safeDictionary = new SafeDictionary <int, int>();
            var fixture        = new Fixture();

            safeDictionary.AddMany(fixture.Create <KeyValuePair <int, int> >, 3);
            var array = new KeyValuePair <int, int> [3];

            safeDictionary.CopyTo(array, 0);
            array.SequenceEqual(safeDictionary).Should().Be(true);
        }
