deserializing json in .net

I have this Json response:
Dim json As String = "{
            'ResponseIG' :{
               'Email': 'james@example.com',
               'Active': true,
               'Roles': [
                       'User',
                       'Admin'
               ]
             }
 }"

I am trying to create the classes to  read this Json string   and  I'm using
JsonConvert.DeserializeObject  to do it

Can anyone help with the classes and how do i use JsonConvert.DeserializeObject to read the data?

I am having issues figuring out how to get inside the  'ResponseIG'   level to read the rest of the data.

This is the classes that i created:

 Public Class Rootobject
        Public Property ResponseIG As Responseig
    End Class

    Public Class Responseig
        Public Property Email As String
        Public Property Active As Boolean
        Public Property CreatedDate As Date
        Public Property Roles() As String
    End Class

And i making this call to get the data
Dim response As Rootobject = JsonConvert.DeserializeObject(Of Rootobject)(json)

But when i looked at the response object it is empty.

Thanks

Create a new class:

public class TheRoot
{
}

Open in new window


Name it whatever you like. Within this new class, add a property with name ResponseIG:

public class TheRoot
{
    public XXXX ResponseIG { get; set; }
}

Open in new window


Now you need a new class to represent the XXXX:

public class ResponseIGClass
{
}

Open in new window


Again, name it whatever you like. Replace the XXXX now:

public class TheRoot
{
    public ResponseIGClass ResponseIG { get; set; }
}

Open in new window


Now you need to add the remaining properties to the sub-class:

public class ResponseIGClass
{
    public string Email { get; set; }
    public bool Active { get; set; }
    public string[] Roles { get; set; }
}

Open in new window


Do note that your Roles property is an array in the JSON, so it needs to be an array in the .NET code.

Once you have all of that put together, you should be able to deserialize:

string json = "the JSON";
TheRoot instance = JsonConvert.DeserializeObject<TheRoot>(json);

Open in new window

just a small problem.

just change:
Public Property Roles() As String
for
Public Property Roles As String()

Thanks for your answer.
i followed your steps, but the property ResponseIG of the instance object is still nothing after runnin this line:
TheRoot instance = JsonConvert.DeserializeObject<TheRoot>(json);

Anything else i might be missing??

thanks
