简单使用Newtonsoft。Json和Newtonsoft.Json.Linq库。

        //Create my object
        var myData = new
        {
            Host = @"sftp.myhost.gr",
            UserName = "my_username",
            Password = "my_password",
            SourceDir = "/export/zip/mypath/",
            FileName = "my_file.zip"
        };

        //Tranform it to Json object
        string jsonData = JsonConvert.SerializeObject(myData);

        //Print the Json object
        Console.WriteLine(jsonData);

        //Parse the json object
        JObject jsonObject = JObject.Parse(jsonData);

        //Print the parsed Json object
        Console.WriteLine((string)jsonObject["Host"]);
        Console.WriteLine((string)jsonObject["UserName"]);
        Console.WriteLine((string)jsonObject["Password"]);
        Console.WriteLine((string)jsonObject["SourceDir"]);
        Console.WriteLine((string)jsonObject["FileName"]);

我发现您根本不需要序列化器。如果将对象作为List返回。 让我举个例子。

在asmx中，我们使用传递的变量获取数据

// return data
[WebMethod(CacheDuration = 180)]
public List<latlon> GetData(int id) 
{
    var data = from p in db.property 
               where p.id == id 
               select new latlon
               {
                   lat = p.lat,
                   lon = p.lon

               };
    return data.ToList();
}

public class latlon
{
    public string lat { get; set; }
    public string lon { get; set; }
}

然后使用jquery访问服务，传递该变量。

// get latlon
function getlatlon(propertyid) {
var mydata;

$.ajax({
    url: "getData.asmx/GetLatLon",
    type: "POST",
    data: "{'id': '" + propertyid + "'}",
    async: false,
    contentType: "application/json;",
    dataType: "json",
    success: function (data, textStatus, jqXHR) { //
        mydata = data;
    },
    error: function (xmlHttpRequest, textStatus, errorThrown) {
        console.log(xmlHttpRequest.responseText);
        console.log(textStatus);
        console.log(errorThrown);
    }
});
return mydata;
}

// call the function with your data
latlondata = getlatlon(id);

我们得到了答案。

{"d":[{"__type":"MapData+latlon","lat":"40.7031420","lon":"-80.6047970}]}

这个库非常适合用于c#中的JSON

http://james.newtonking.com/pages/json-net.aspx

这个代码片段使用了。net 3.5中System.Runtime.Serialization.Json中的DataContractJsonSerializer。

public static string ToJson<T>(/* this */ T value, Encoding encoding)
{
    var serializer = new DataContractJsonSerializer(typeof(T));

    using (var stream = new MemoryStream())
    {
        using (var writer = JsonReaderWriterFactory.CreateJsonWriter(stream, encoding))
        {
            serializer.WriteObject(writer, value);
        }

        return encoding.GetString(stream.ToArray());
    }
}

包括:

使用System.Text.Json;

然后像这样序列化你的object_to_serialize: JsonSerializer.Serialize (object_to_serialize)

您可以使用JavaScriptSerializer类来构建一个有用的扩展方法。

文章中的代码:

namespace ExtensionMethods
{
    public static class JSONHelper
    {
        public static string ToJSON(this object obj)
        {
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            return serializer.Serialize(obj);
        }

        public static string ToJSON(this object obj, int recursionDepth)
        {
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            serializer.RecursionLimit = recursionDepth;
            return serializer.Serialize(obj);
        }
    }
}

用法:

using ExtensionMethods;

...

List<Person> people = new List<Person>{
                   new Person{ID = 1, FirstName = "Scott", LastName = "Gurthie"},
                   new Person{ID = 2, FirstName = "Bill", LastName = "Gates"}
                   };


string jsonString = people.ToJSON();
