在 C# 中獲取在 Dictionary 中迭代的列舉器
以下程式碼可用於獲取在 Dictionary 中迭代的列舉器 −
示例
using System;
using System.Collections;
using System.Collections.Generic;
public class Demo {
public static void Main(){
Dictionary<int, string> dict = new Dictionary<int, string>();
dict.Add(100, "Laptop");
dict.Add(150, "Desktop");
dict.Add(200, "Earphone");
dict.Add(300, "Tablet");
dict.Add(500, "Speakers");
dict.Add(750, "HardDisk");
dict.Add(1000, "SSD");
IDictionaryEnumerator demoEnum = dict.GetEnumerator();
Console.WriteLine("Enumerator iterating key-value pairs...");
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
}
}輸出
這將產生以下輸出 −
Enumerator iterating key-value pairs... Key = 100, Value = Laptop Key = 150, Value = Desktop Key = 200, Value = Earphone Key = 300, Value = Tablet Key = 500, Value = Speakers Key = 750, Value = HardDisk Key = 1000, Value = SSD
示例
下面我門將看到另一個示例 −
using System;
using System.Collections;
using System.Collections.Generic;
public class Demo {
public static void Main(){
Dictionary<string, string> dict = new Dictionary<string, string>();
dict.Add("One", "Laptop");
dict.Add("Two", "Desktop");
dict.Add("Three", "Earphone");
dict.Add("Four", "Tablet");
dict.Add("Five", "Speakers");
dict.Add("Six", "HardDisk");
dict.Add("Seven", "SSD");
dict.Add("Eight", "Keyboard");
dict.Add("Nine", "Mouse");
IDictionaryEnumerator demoEnum = dict.GetEnumerator();
Console.WriteLine("Enumerator iterating key-value pairs...");
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
}
}輸出
這將產生以下輸出 −
Enumerator iterating key-value pairs... Key = One, Value = Laptop Key = Two, Value = Desktop Key = Three, Value = Earphone Key = Four, Value = Tablet Key = Five, Value = Speakers Key = Six, Value = HardDisk Key = Seven, Value = SSD Key = Eight, Value = Keyboard Key = Nine, Value = Mouse
