c# - 创建 IEnumerable> 使用 C# 的对象？

Question

出于测试目的，我需要IEnumerable<KeyValuePair<string, string>>使用以下示例键值对创建一个对象：

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

最简单的方法是什么？

Answer 1

any of:

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

or

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

or:

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

Answer 2

Dictionary<string, string> implements IEnumerable<KeyValuePair<string,string>>.

Answer 3

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

Answer 4

您可以简单地分配Dictionary<K, V>给IEnumerable<KeyValuePair<K, V>>

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

如果这不起作用，您可以尝试 -

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

Answer 5

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

Is that what you mean, or is there more to it?
