从C#中的HybridDictionary中删除指定的键条目
要从HybridDcitionary中删除指定的键条目，代码如下-
示例
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
示例
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
