使用C＃創建IEnumerable <KeyValuePair <string，string >>對象？

Question

出於測試目的，我需要具有下列樣品鍵值對創建IEnumerable<KeyValuePair<string, string>>對象：

Key = Name | Value : John 
Key = City | Value : NY 

什麼是最簡單的方法呢？

Answer 1

的任何：

values = new Dictionary<string,string> { {"Name", "John"}, {"City", "NY"} }; 

或

values = new [] { 
     new KeyValuePair<string,string>("Name","John"), 
     new KeyValuePair<string,string>("City","NY") 
    }; 

或：

values = (new[] { 
     new {Key = "Name", Value = "John"}, 
     new {Key = "City", Value = "NY"} 
    }).ToDictionary(x => x.Key, x => x.Value); 

Answer 2

var List = new List<KeyValuePair<String, String>> { 
    new KeyValuePair<String, String>("Name", "John"), 
    new KeyValuePair<String, String>("City" , "NY") 
}; 

Answer 3

Dictionary<string, string>實現IEnumerable<KeyValuePair<string,string>>。

Answer 4

Dictionary<string,string> testDict = new Dictionary<string,string>(2); 
testDict.Add("Name","John"); 
testDict.Add("City","NY"); 

這是你的意思，還是有更多的呢？

Answer 5

你可以簡單地分配給Dictionary<K, V>IEnumerable<KeyValuePair<K, V>>

IEnumerable<KeyValuePair<string, string>> kvp = new Dictionary<string, string>(); 

如果不工作，你可以嘗試 -

IDictionary<string, string> dictionary = new Dictionary<string, string>(); 
      IEnumerable<KeyValuePair<string, string>> kvp = dictionary.Select((pair) => pair);
