C#程序查找两个或更多词典的联合
首先，设置两个字典-
Dictionary < string, int > dict1 = new Dictionary < string, int > ();
dict1.Add("water", 1);
dict1.Add("food", 2);
Dictionary < string, int > dict2 = new Dictionary < string, int > ();
dict2.Add("clothing", 3);
dict2.Add("shelter", 4);现在，创建HashSet并使用UnionsWith()method查找以上两个Dictionary之间的联合-
HashSet < string > hSet = new HashSet < string > (dict1.Keys); hSet.UnionWith(dict2.Keys);
以下是完整的代码-
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("water", 1);
dict1.Add("food", 2);
Dictionary < string, int > dict2 = new Dictionary < string, int > ();
dict2.Add("clothing", 3);
dict2.Add("shelter", 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);
}
}
}输出结果
Union of Dictionary... water food clothing shelter
