Encoding Apostrophe with JSON.NET

Question

Say I have a class like

public class MyTestClass
{
    public MyTestClass()
    {
        Testing = "check ' out";
    }
    public string Testing { get; set; }
}

And JavascriptSerializer/JsonNet serializers like :

public IHtmlString ToJsonNet(object value)
{
    return new MvcHtmlString(JsonConvert.SerializeObject(value));
}

public IHtmlString ToJson(object value)
{
    var json = new JavaScriptSerializer();
    return new MvcHtmlString(json.Serialize(value));
}

Then in a view I have

 @(Serializers.ToJsonNet(new MyTestClass()))
 @(Serializers.ToJson(new MyTestClass()))

The JsonNet will return {"Testing":"check ' out"}, while the JavascriptSerializer will return {"Testing":"check \u0027 out"}. I wish to create a javascript object like

var model = $.parseJSON('@jsonString');

But this only works if the apostrophe is encoded. Otherwise, the apostrophe makes my javacript look like

var model = $.parseJSON('{"Testing":"check ' out"}');

which fails because the inserted apostrophe makes parseJSON escape my string too early.

JavascriptSerializer encodes the apostrophe as \u0027 by default while JSON.NET (which I want to use) does not. How can I change JSON.NET to do this? Is there a setting I'm missing? Is there a different way I can parse my JSON string into javascript where the apostrophe is OK?

Which version of jquery are you using? – nemesv May 16 '12 at 20:42 — nemesv, May 16 '12 at 20:42
were you able to solve the issue with JSON.NET? – CoffeeCode Nov 23 '12 at 17:08 — CoffeeCode, Nov 23 '12 at 17:08

The following answer indicates that the two should be equivalent. https://stackoverflow.com/a/5022386/1388165

If it is the parseJSON call failing, perhaps double quotes instead of single quotes in the argument would help.

Because the jsonstring contains both double quotes and single quotes, using either of them in the parseJson currently causes a failure because it escapes the jsonString early. – user1399487 May 16 '12 at 19:57

Have you tried escaping the apostrophe with a "\"?

Something like Testing = "check \' out";

You should also take a look at this post, there seem to be some interesting answers for you here.

Try this:

{"Testing":"check \u0027 out"}

When I paste text into an html text area from Microsoft Word and then use that value to serialize it in C#, the apostrophe does not get serialized as \u0027 but instead it remains as "'" character. Any thoughts? – nav Jan 15 '15 at 15:14
