Deserialize JSON String in code behind

Question

Is there is any other way deserialize JSON string,rather than using the Newtonsoft library? I've a string like

string json = "{status : '1',message : '<tr><th>Date</th><th>Description</th><th>Reference</th> <th>Code</th><th>Dept Code</th><th>Debit</th><th>Credit</th></tr>'}";

if i want to access the message property in code behind file, how can i do that?

Answer 1

You could use the DataContractJsonSerializer. Deserialize it as a class with what you want to extract, e.g.

[DataContract]
public class Message
{
 [DataMember]
 public string message { get; set; }
}

• Arooran: Which namespace do i need to use for that?thanks for your prompt answer
• Tim S.: DataContractJsonSerializer is in System.Runtime.Serialization.Json. DataContractAttribute and DataMemberAttribute are in System.Runtime.Serialization. The Message class can be in the namespace of your choosing.

Answer 2

Consider this:

You need this required namespaces:

using System.Web.Script.Serialization;

Consider this class:

[Serializable]
public class Foo
{
 public int status { get; set; }
 public string message { get; set; }
}

SerializableAttribute is required to work with JavaScriptSerializer

USAGE

JavaScriptSerializer serializer = new JavaScriptSerializer();
// Deserialize
Foo foo = serializer.Deserialize<Foo>(json);
//now you have access to...
var status = foo.status;
var message = foo.message;

You may also deserialize with JavaScriptSerializer in a Dictionary. See this:

Dictionary<string, object> ds = serializer .Deserialize<Dictionary<string, object>>(json);
var status = ds["status"].ToString();
var message = ds["message"].ToString();

• Arooran: Which namespace do i need to call for this. thanks for your reply
• Abdul Munim: Added namespace on the answer, please check
• Arooran: i got an error when passing a table data as message property. Invalid object passed in, ':' or '}' expected. (37): {status : 1 , message : '<table id='excelDoc'><tr><th>Date</th><th>Description</th><th>Reference</th><th>Nominal Code</th><th>Dept Code</th><th>Debit</th><th>Credit</th></tr><tr><td>21/11/2011</td><td>Nov depreciation </td><td>Dep jnl</td><td></td><td></td><td class='db'></td><td class='cr'></td></tr><tr><td></td><td></td><td></td><td>1150</td><td>100</td><td class='db'>0.00</td><td class='cr'>50.00</td></tr></table>'}
• Abdul Munim: You can't use ' within a string, it must be escaped with \'

Answer 3

1. Create class

    public class TestM
    {
    public string status { get; set; }
    public string message { get; set; }
    }
   

2. Than use this in your code

    JavaScriptSerializer ser = new JavaScriptSerializer();
    TestM t = ser.Deserialize<TestM>("{status : '1',message : '<tr><th>Date</th><th>Description</th><th>Reference</th> <th>Code</th><th>Dept Code</th><th>Debit</th><th>Credit</th></tr>'}");
   

• Arooran: thanks for your reply it is possible to use anonymous object.
• Arooran: var TestM = new { status = string.Empty, message = string.Empty }
• dotnetstep: anonymous object.. i am not quite sure
