            Dictionary<int, string>.ValueCollection collection = productList.Values;            foreach (var item in collection)            {                MessageBox.Show(string.Format("{0}", item));            }            //productList.Remove(1);            //productList.Clear();            MessageBox.Show("判断是否包含键值对中的键为”1“的值");            if (productList.ContainsKey(1))            {                MessageBox.Show(productList[1]);            }            MessageBox.Show("判断是否包含键值对中的值为”ProductionTwo“的值");            if (productList.ContainsValue("ProductionTwo"))            {                MessageBox.Show(string.Format("{0}", "this really exists"));            }        }
