将JSON反序列化为KeyValue对的列表

问题描述：

我有以下json:

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

如何将其反序列化为NameValuePair<string, string>的列表/数组?

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

示例:

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

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

上面的代码运行，但是列表中的数据为null.我可以将数组提取到List<Object>.

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

答

首先，您不应该使用JavaScriptSerializer，Microsoft甚至明确表示

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

要在Json.NET中反序列化对象，语法非常相似:

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);
