JavaScriptSerializer namespace issue
提问by Jeff
I am having a problem trying to implement the JavaScriptSerializerto parse a JSON string received from a server.
我在尝试实现JavaScriptSerializer解析从服务器接收到的 JSON 字符串时遇到问题。
I implemented the following code:
我实现了以下代码：
responseFromServer = readStream.ReadLine();
JavaScriptSerializer ser = new JavaScriptSerializer();
var dict = new JavaScriptSerializer().Deserialize<Dictionary<string, object>>(responseFromServer);
var status = dict["notificationType"];
Debug.WriteLine(status);
I added using System.Web.Script.Serialization;
我加了 using System.Web.Script.Serialization;
Visual C# 2010 Express is telling me the namespace name Scriptdoes not exist in the namespace System.Web. As a result the JavaScriptSerializeris not valid.
Visual C# 2010 Express 告诉我命名空间Script中不存在命名空间名称System.Web。结果JavaScriptSerializer是无效的。
What am I missing to use this, or is there a better way to parse the JSON string?
我缺少什么来使用它，或者有更好的方法来解析 JSON 字符串吗？
