合并两个字典的C#程序
设置两个字典-
Dictionary < string, int > dict1 = new Dictionary < string, int > ();dict1.Add("laptop", 1);
dict1.Add("desktop", 2);
Dictionary < string, int > dict2 = new Dictionary < string, int > ();
dict2.Add("desktop", 3);
dict2.Add("tablet", 4);
dict2.Add("mobile", 5);
现在使用HashSet和UnionWith()
method合并两个字典-
HashSet < string > hSet = new HashSet < string > (dict1.Keys);hSet.UnionWith(dict2.Keys);
这是完整的代码-
示例
using System;using System.Collections.Generic;
class Program {
static void Main() {
Dictionary < string, int > dict1 = new Dictionary < string, int > ();
dict1.Add("laptop", 1);
dict1.Add("desktop", 2);
Dictionary < string, int > dict2 = new Dictionary < string, int > ();
dict2.Add("desktop", 3);
dict2.Add("tablet", 4);
dict2.Add("mobile", 5);
HashSet < string > hSet = new HashSet < string > (dict1.Keys);
hSet.UnionWith(dict2.Keys);
Console.WriteLine("Merged Dictionary...");
foreach(string val in hSet) {
Console.WriteLine(val);
}
}
}
