从C#中的OrderedDictionary中删除具有指定键的条目
要从C#中的OrdererdDictionary中删除具有指定键的条目，代码如下-
示例
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main() {
OrderedDictionary dict = new OrderedDictionary();
dict.Add("A", "Books");
dict.Add("B", "Electronics");
dict.Add("C", "Smart Wearables");
dict.Add("D", "Pet Supplies");
dict.Add("E", "Clothing");
dict.Add("F", "Footwear");
Console.WriteLine("OrderedDictionary elements...");
foreach(DictionaryEntry d in dict) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("Count of elements in OrderedDictionary = " + dict.Count);
dict.Remove("E");
Console.WriteLine("Count of elements in OrderedDictionary (Updated)= " + dict.Count);
}
}输出结果
这将产生以下输出-
OrderedDictionary elements... A Books B Electronics C Smart Wearables D Pet Supplies E Clothing F Footwear Count of elements in OrderedDictionary = 6 Count of elements in OrderedDictionary (Updated)= 5
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() {
OrderedDictionary dict = new OrderedDictionary();
dict.Add("A", "One");
dict.Add("B", "Two");
dict.Add("C", "Three");
dict.Add("D", "Four");
Console.WriteLine("OrderedDictionary elements...");
foreach(DictionaryEntry d in dict) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("Count of elements in OrderedDictionary = " + dict.Count);
dict.Remove("C");
dict.Remove("D");
Console.WriteLine("Count of elements in OrderedDictionary (Updated)= " + dict.Count);
}
}输出结果
这将产生以下输出-
OrderedDictionary elements... A One B Two C Three D Four Count of elements in OrderedDictionary = 4 Count of elements in OrderedDictionary (Updated)= 2
