C# SortedDictionary.Add() 方法使用实例

C#中的SortedDictionary.Add()方法用于将具有指定键和值的元素添加到SortedDictionary<TKey,TValue>中。

语法

语法如下-

public void Add (TKey key, TValue val);

在上方，value键是要添加的元素的键，而val是要添加的元素的值。

示例

现在让我们看一个例子-

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); } }

输出结果

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

让我们看另一个例子-

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键值对..."); IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); Console.WriteLine("\nSortedDictionary的键为F? = "+sortedDict.ContainsKey("F")); } }

输出结果

这将产生以下输出-

SortedDictionary键值对... 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 SortedDictionary的键为F? = True
