JavaScriptSerializer namespace issue

问题

I am having a problem trying to implement the JavaScriptSerializer to parse a JSON string received from a server.

I implemented the following code:

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;

Visual C# 2010 Express is telling me the namespace name Script does not exist in the namespace System.Web. As a result the JavaScriptSerializer is not valid.

What am I missing to use this, or is there a better way to parse the JSON string?

回答1:

JavaScriptSerializer is situated in System.Web.Extensions Assembly. You should add it to your project references.

You can get this information in MSDN

Assembly: System.Web.Extensions (in System.Web.Extensions.dll)

回答2:

System.Web.Script.Serialization.JavaScriptSerializer oSerializer = new System.Web.Script.Serialization.JavaScriptSerializer();
var dict = oSerializer.Deserialize<Dictionary<string, object>>(responseFromServer);

This will help you to get the value

回答3:

Add Reference System.Web.Extensions

then type using System.Web.Script.Serialization;

Now you should get JavaScriptSerializer valid.

You can use better approach by adding Newtonsoft.Json.dll through

Add Reference. See details here : http://json.codeplex.com/
