Deserialize json to list of KeyValue pairs [duplicate]

问题

This question already has answers here:

How can I deserialize JSON to a simple Dictionary<string,string> in ASP.NET? (21 answers)

Closed last year.

I have the following json:

[
   {
      "key":"key1",
      "value":"val1"
   },
   {
      "key":"key2",
      "value":"val2"
   }
]

How can I deserialize it into an list/array of NameValuePair<string, string>?

Example:

var json = "[{\"key\":\"key1\",\"value\":\"val1\"},{\"key\":\"key2\",\"value\":\"val2\"}]";

var serializer = new JavaScriptSerializer();
var result = serializer.Deserialize<List<KeyValuePair<string,string>>>(json);

The above code runs but the data inside the list is null. I can extract the array into an List<Object> though.

回答1:

First off, you should not be using JavaScriptSerializer, Microsoft even explicitly says that in the JavaScriptSerializer docs.

To deserialize an object in Json.NET the syntax is very similar:

var json = "[{\"key\":\"key1\",\"value\":\"val1\"},{\"key\":\"key2\",\"value\":\"val2\"}]";

var result = JsonConvert.DeserializeObject<List<KeyValuePair<string,string>>>(json);

Fiddle here
