要从HybridDcitionary中删除指定的键条目,代码如下-
using System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main() { HybridDictionary dict1 = new HybridDictionary(); dict1.Add("A", "Books"); dict1.Add("B", "Electronics"); dict1.Add("C", "Smart Wearables"); dict1.Add("D", "Pet Supplies"); dict1.Add("E", "Clothing"); dict1.Add("F", "Footwear"); Console.WriteLine("HybridDictionary1 elements..."); foreach(DictionaryEntry d in dict1) { Console.WriteLine(d.Key + " " + d.Value); } HybridDictionary dict2 = new HybridDictionary(); dict2.Add("1", "One"); dict2.Add("2", "Two"); dict2.Add("3", "Three"); dict2.Add("4", "Four"); dict2.Add("5", "Five"); dict2.Add("6", "Six"); Console.WriteLine("\nHybridDictionary2 key-value pairs..."); IDictionaryEnumerator demoEnum = dict2.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); dict2.Remove("3"); Console.WriteLine("\nHybridDictionary2 key-value pairs...UPDATED"); demoEnum = dict2.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); } }
输出结果
这将产生以下输出-
HybridDictionary1 elements... A Books B Electronics C Smart Wearables D Pet Supplies E Clothing F Footwear HybridDictionary2 key-value pairs... Key = 1, Value = One Key = 2, Value = Two Key = 3, Value = Three Key = 4, Value = Four Key = 5, Value = Five Key = 6, Value = Six HybridDictionary2 key-value pairs...UPDATED Key = 1, Value = One Key = 2, Value = Two Key = 4, Value = Four Key = 5, Value = Five Key = 6, Value = Six
让我们看另一个例子-
using System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main() { HybridDictionary dict = new HybridDictionary(); dict.Add("1", "Marketing"); dict.Add("2", "Purchase"); dict.Add("3", "Sales"); dict.Add("4", "IT"); dict.Add("5", "Finance"); dict.Add("6", "Operations"); Console.WriteLine("HybridDictionary key-value pairs..."); IDictionaryEnumerator demoEnum = dict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); dict.Remove("3"); Console.WriteLine("\nHybridDictionary key-value pairs...UPDATED"); demoEnum = dict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); dict.Remove("4"); Console.WriteLine("\nHybridDictionary key-value pairs...UPDATED"); demoEnum = dict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); } }
输出结果
这将产生以下输出-
HybridDictionary key-value pairs... Key = 1, Value = Marketing Key = 2, Value = Purchase Key = 3, Value = Sales Key = 4, Value = IT Key = 5, Value = Finance Key = 6, Value = Operations HybridDictionary key-value pairs...UPDATED Key = 1, Value = Marketing Key = 2, Value = Purchase Key = 4, Value = IT Key = 5, Value = Finance Key = 6, Value = Operations HybridDictionary key-value pairs...UPDATED Key = 1, Value = Marketing Key = 2, Value = Purchase Key = 5, Value = Finance Key = 6, Value = Operations
