In Searchable Names Part 1 seaction 2

Bad:

// What the heck is data for?
var data = new { Name = "John", Age = 42 };

var stream1 = new MemoryStream();
var ser1 = new DataContractJsonSerializer(typeof(object));
ser1.WriteObject(stream1, data);

stream1.Position = 0;
var sr1 = new StreamReader(stream1);
Console.Write("JSON form of Data object: ");
Console.WriteLine(sr1.ReadToEnd());

Good:

var person = new Person
{
    Name = "John",
    Age = 42
};

var stream2 = new MemoryStream();
var ser2 = new DataContractJsonSerializer(typeof(Person));
ser2.WriteObject(stream2, data);

stream2.Position = 0;
var sr2 = new StreamReader(stream2);
Console.Write("JSON form of Data object: ");
Console.WriteLine(sr2.ReadToEnd());

As you can see in ser2.WriteObject(stream2, data); should be person not data as data has not been declared and to match what bad code block is doing

You are also not following the very first rule "Avoid using bad names". What do "ser2 and "sr2" stand for?
"stream2" is not a good name either.

@olmeyer I agree i was not asking about all the incorrect items on the good side

ar person = new Person
{
    Name = "John",
    Age = 42
};

var stream2 = new MemoryStream();
var ser2 = new DataContractJsonSerializer(typeof(Person));
ser2.WriteObject(stream2, data);  // i was asking about here should it not say person instead of data
