我有两个不同大小的不同字典，我们可以比较这两个字典并提取字典1中不存在的值吗？



我是什么尝试过：

使用Linq Except方法：

 Dictionary< string，string> d1 =  new 字典< string，string>（）; 
 d1.Add（  Joe，   2，Barfield Way）; 
 d1.Add（  Mike，   17，Apollo Avenue）; 
 d1.Add（  Jane，   69，Lance Drive）; 
 Dictionary< string，string> d2 =  new 字典< string，string>（）; 
 d2.Add（  Joe，   2，Barfield Way）; 
 d2.Add（  Jane，   69，Lance Drive）; 
  var  diff = d1.Except（d2）; 
 

I have two different dictionaries of different size, can we compare both these and extract the values which are not there in dictionary 1?

解决方案

Use the Linq Except method:

Dictionary<string, string> d1 = new Dictionary<string, string>();
d1.Add("Joe", "2, Barfield Way");
d1.Add("Mike", "17, Apollo Avenue");
d1.Add("Jane", "69, Lance Drive");
Dictionary<string, string> d2 = new Dictionary<string, string>();
d2.Add("Joe", "2, Barfield Way");
d2.Add("Jane", "69, Lance Drive");
var diff = d1.Except(d2);
