C# 程序组合两键字典
首先,设置要组合的字典 −
Dictionary <string, int> dict1 = new Dictionary <string, int> (); dict1.Add("one", 1); dict1.Add("Two", 2); Dictionary <string, int> dict2 = new Dictionary <string, int> (); dict2.Add("Three", 3); dict2.Add("Four", 4);
现在,使用 HashSet 将其组合起来。为此方法使用的是 UnionWith() −
HashSet <string> hSet = new HashSet <string> (dict1.Keys); hSet.UnionWith(dict2.Keys);
以下为完整的代码 −
示例
using System; using System.Collections.Generic; public class Program { public static void Main() { Dictionary <string, int> dict1 = new Dictionary <string, int> (); dict1.Add("one", 1); dict1.Add("Two", 2); Dictionary <string, int> dict2 = new Dictionary <string, int> (); dict2.Add("Three", 3); dict2.Add("Four", 4); HashSet <string> hSet = new HashSet <string> (dict1.Keys); hSet.UnionWith(dict2.Keys); Console.WriteLine("Union of Dictionary..."); foreach(string val in hSet) { Console.WriteLine(val); } } }
输出
Union of Dictionary... one Two Three Four
