最简单的方法是:

只需包含这个DLL文件。

像这样使用代码:

dynamic json = new JDynamic("{a:'abc'}");
// json.a is a string "abc"

dynamic json = new JDynamic("{a:3.1416}");
// json.a is 3.1416m

dynamic json = new JDynamic("{a:1}");
// json.a is

dynamic json = new JDynamic("[1,2,3]");
/json.Length/json.Count is 3
// And you can use json[0]/ json[2] to get the elements

dynamic json = new JDynamic("{a:[1,2,3]}");
//json.a.Length /json.a.Count is 3.
// And you can use  json.a[0]/ json.a[2] to get the elements

dynamic json = new JDynamic("[{b:1},{c:1}]");
// json.Length/json.Count is 2.
// And you can use the  json[0].b/json[1].c to get the num.

试试这个:

  var units = new { Name = "Phone", Color= "White" };
    var jsonResponse = JsonConvert.DeserializeAnonymousType(json, units);

如何解析简单的JSON内容与动态& JavaScriptSerializer

请添加System.Web.Extensions的引用，并使用System.Web.Script.Serialization添加此命名空间;在前:

public static void EasyJson()
{
    var jsonText = @"{
        ""some_number"": 108.541,
        ""date_time"": ""2011-04-13T15:34:09Z"",
        ""serial_number"": ""SN1234""
    }";

    var jss = new JavaScriptSerializer();
    var dict = jss.Deserialize<dynamic>(jsonText);

    Console.WriteLine(dict["some_number"]);
    Console.ReadLine();
}

如何解析嵌套和复杂的json与动态和JavaScriptSerializer

请添加System.Web.Extensions的引用，并使用System.Web.Script.Serialization添加此命名空间;在前:

public static void ComplexJson()
{
    var jsonText = @"{
        ""some_number"": 108.541,
        ""date_time"": ""2011-04-13T15:34:09Z"",
        ""serial_number"": ""SN1234"",
        ""more_data"": {
            ""field1"": 1.0,
            ""field2"": ""hello""
        }
    }";

    var jss = new JavaScriptSerializer();
    var dict = jss.Deserialize<dynamic>(jsonText);

    Console.WriteLine(dict["some_number"]);
    Console.WriteLine(dict["more_data"]["field2"]);
    Console.ReadLine();
}

你想要的DynamicJSONObject对象包含在ASP. web . helpers .dll中。NET Web Pages包，它是WebMatrix的一部分。

最简单的方法是:

只需包含这个DLL文件。

像这样使用代码:

dynamic json = new JDynamic("{a:'abc'}");
// json.a is a string "abc"

dynamic json = new JDynamic("{a:3.1416}");
// json.a is 3.1416m

dynamic json = new JDynamic("{a:1}");
// json.a is

dynamic json = new JDynamic("[1,2,3]");
/json.Length/json.Count is 3
// And you can use json[0]/ json[2] to get the elements

dynamic json = new JDynamic("{a:[1,2,3]}");
//json.a.Length /json.a.Count is 3.
// And you can use  json.a[0]/ json.a[2] to get the elements

dynamic json = new JDynamic("[{b:1},{c:1}]");
// json.Length/json.Count is 2.
// And you can use the  json[0].b/json[1].c to get the num.

你可以扩展JavaScriptSerializer来递归复制它创建的字典来扩展对象，然后动态地使用它们:

static class JavaScriptSerializerExtensions
{
    public static dynamic DeserializeDynamic(this JavaScriptSerializer serializer, string value)
    {
        var dictionary = serializer.Deserialize<IDictionary<string, object>>(value);
        return GetExpando(dictionary);
    }

    private static ExpandoObject GetExpando(IDictionary<string, object> dictionary)
    {
        var expando = (IDictionary<string, object>)new ExpandoObject();

        foreach (var item in dictionary)
        {
            var innerDictionary = item.Value as IDictionary<string, object>;
            if (innerDictionary != null)
            {
                expando.Add(item.Key, GetExpando(innerDictionary));
            }
            else
            {
                expando.Add(item.Key, item.Value);
            }
        }

        return (ExpandoObject)expando;
    }
}

然后，您只需要为您在其中定义扩展的名称空间使用一个using语句(考虑在System.Web.Script.Serialization中定义它们…)另一个技巧是不使用命名空间，那么你根本不需要using语句)，你可以像这样使用它们:

var serializer = new JavaScriptSerializer();
var value = serializer.DeserializeDynamic("{ 'Name': 'Jon Smith', 'Address': { 'City': 'New York', 'State': 'NY' }, 'Age': 42 }");

var name = (string)value.Name; // Jon Smith
var age = (int)value.Age;      // 42

var address = value.Address;
var city = (string)address.City;   // New York
var state = (string)address.State; // NY
