C# SortedDictionary.Add() 方法
C# 中的 SortedDictionary.Add() 方法用于向 SortedDictionary<TKey, TValue> 中添加具有指定键和值的元素。
语法
语法如下 -
public void Add (TKey key, TValue val);
此处,value key 是要添加的元素的键,而 val 是要添加的元素的值。
示例
现在我们来看一个示例 -
using System; using System.Collections; using System.Collections.Generic; public class Demo { public static void Main(){ SortedDictionary<int, string> sortedDict = new SortedDictionary<int, string>(); sortedDict.Add(100, "Mobile"); sortedDict.Add(200, "Laptop"); sortedDict.Add(300, "Desktop"); sortedDict.Add(400, "Speakers"); sortedDict.Add(500, "Headphone"); sortedDict.Add(600, "Earphone"); Console.WriteLine("SortedDictionary key-value pairs..."); IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); } }
输出
这将产生以下输出 -
SortedDictionary key-value pairs... Key = 100, Value = Mobile Key = 200, Value = Laptop Key = 300, Value = Desktop Key = 400, Value = Speakers Key = 500, Value = Headphone Key = 600, Value = Earphone
示例
我们来看另一个示例 -
using System; using System.Collections; using System.Collections.Generic; public class Demo { public static void Main(){ SortedDictionary<string, string> sortedDict = new SortedDictionary<string, string>(); sortedDict.Add("A", "John"); sortedDict.Add("B", "Andy"); sortedDict.Add("C", "Tim"); sortedDict.Add("D", "Ryan"); sortedDict.Add("E", "Kevin"); sortedDict.Add("F", "Katie"); sortedDict.Add("G", "Brad"); Console.WriteLine("SortedDictionary key-value pairs..."); IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); Console.WriteLine("
The SortedDictionary has the key F? = "+sortedDict.ContainsKey("F")); } }
输出
这将产生以下输出 -
SortedDictionary key-value pairs... Key = A, Value = John Key = B, Value = Andy Key = C, Value = Tim Key = D, Value = Ryan Key = E, Value = Kevin Key = F, Value = Katie Key = G, Value = Brad The SortedDictionary has the key F? = True
