1. 先添加System.Web.Extensions.dll引用
var js = new System.Web.Script.Serialization.JavaScriptSerializer();
string test_json = "{"name":"tom","nickname":"tony","sex":"male","age":20,"email":"123@123.com"}";
var jarr = js.Deserialize<Dictionary<string, object>>(test_json);
foreach (var j in jarr)
{
Console.WriteLine(string.Format("{0}:{1}", j.Key, j.Value));
}
2.使用这个类 Newtosonjson.dll
