Most likely, the slashes are an artifact because you copied them out of the VisualStudio debugger. The debugger displays all strings in a way that they could be pasted into C/C# code. They aren't really in the transmitted data.

BTW: These slashes are backward slashes. A forward slash would look like this: /.

I had the same issue, until just a few moments ago. Turns out that I was "double serializing" the JSON string. I use a jQuery <code>$.getJson(</code> AJAX call to a <code>JsonResult</code> controller action. And because the action builds a C# Generic <code>List&lt;t&gt;</code> I thought that I had to use JSON.net/NewtonSoft to convert the C# Generic <code>List&lt;t&gt;</code> to a JSON object before returning the JSON using the following:

<pre><code>return Json(fake, JsonRequestBehavior.AllowGet);
</code></pre>

I didn't have to use the <code>JsonConvert.SerializeObject(</code> method after all, evidently this <code>return</code> will conver the serialization for us.

Hope it helps you or someone else too.

Mostly It occurs due to double serialization. I had same issue a while back where I had to serialize a collection into Json string and even after trying various workarounds I was unable to resolve it. So, at last removed all the serialization code and simply returned the collection object and the serialization was taken care of by default.

After hours of trying to figure this out, one popular response to this question seemed to be spot on accurate for me. But, not in the manner I imagined.

My code was very very simple:

<pre><code>this.Request.CreateResponse(HttpStatusCode.Accepted, new JavaScriptSerializer().Serialize(obj));
</code></pre>

I was sure the the popular response of "double serializing" did not apply to me. After all, I was explicitly serializing my object to JSON only once.

I tried this snippet:

<pre><code>new StringContent(json, System.Text.Encoding.UTF8, "application/json")
</code></pre>

Which did not even seem to contain my data! Instead this is what i received:

<pre><code>{
 "Headers": [
 {
 "Key": "Content-Type",
 "Value": [
 "application/json; charset=utf-8"
 ]
 }
 ]
}
</code></pre>

Hmmm... 
But lo and behold! Looking closely at my original response in the Swagger UI, and after copy and pasting it into a JSON beautifier - I was in fact somehow "double serializing". Using the following code is what yielded the correct JSON response:

<pre><code> this.Request.CreateResponse(HttpStatusCode.Accepted, obj);
</code></pre>

That's right! just send the serializable object directly, no need to serialize to JSON! Seems the response automagically serializes objects into JSON. Hope this helps!

EDIT:
If you begin with a JSON string, like let's say from database, you can deserialize the string into an object and return that object - like so:

<pre><code>object obj = new JavaScriptSerializer().DeserializeObject(json);
this.Request.CreateResponse(HttpStatusCode.Accepted, obj);
</code></pre>

blocks|key|1215225|text|我发现这些答案的组合对我来说是有效的。我是像上面提到的人那样进行双重序列化的。为了使序列化识别JsonProperty属性，必须使用JsonConvert序列化程序。例如，我有一个名为ActualtTarget的属性，但需要将其序列化为实际的-Target。Json结果在序列化时不会识别JsonProperty，因此我使用JsonConvert序列化并返回字符串，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1215226|return+Content(JsonConvert.SerializeObject(myData));|code-block|syntax|javascript|1215227|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

I have found that a combination of the answers work for me. I was double serializing as someone above mentioned. In order for the serialization to recognize your JsonProperty attribute you must use JsonConvert serializer. For instance, I have a property called ActualtTarget but need it to serialize as Actual-Target. The Json result will not recognize the JsonProperty when serializing, so I serialized with JsonConvert and just returned the string like below:

<pre><code>return Content(JsonConvert.SerializeObject(myData));
</code></pre>

In my case in a Generic Handler this helped. if the given string is json will return in try otherwise will return in catch
<pre><code>private static dynamic TryParseJSON(string message)
 {
 try
 {
 var serializer = new JavaScriptSerializer();
 return serializer.Deserialize&lt;dynamic&gt;(message);
 }
 catch
 {
 return message;
 }
 }
</code></pre>

I use MVC4 web-api, c#, and want to return Json using Json.net.
The problem is it comes with &quot;backward slashes&quot;.
I also added this code to Global.asax.
GlobalConfiguration.Configuration.Formatters.XmlFormatter.SupportedMediaTypes.Clear();
Here is what it returns:
<pre><code>&quot;{\&quot;cid\&quot;:1,\&quot;model\&quot;:\&quot;WT50JB\&quot;,\&quot;detail\&quot;:\&quot;sdf??\&quot;,\&quot;unit\&quot;:2,\&quot;time_in\&quot;:\&quot;2012-12-11T19:00:00\&quot;,\&quot;time_out\&quot;:\&quot;2012-12-12T13:00:06.2774691+07:00\&quot;,\&quot;time_used_dd\&quot;:0.0,\&quot;time_used_hh\&quot;:0.0}&quot;
</code></pre>
So what I want to see is this:
{&quot;cid&quot;:1,&quot;model&quot;:&quot;WT50JB&quot;,&quot;detail&quot;:&quot;sdf??&quot;,&quot;unit&quot;:2,&quot;time_in&quot;:&quot;2012-12-11T19:00:00&quot;,&quot;time_out&quot;:&quot;2012-12-12T13:08:50.5444555+07:00&quot;,&quot;time_used_dd&quot;:0.0,&quot;time_used_hh&quot;:0.0}
Here is JsonConvertor
<pre><code>string json = JsonConvert.SerializeObject(myObj);
</code></pre>

Return Json, but it includes backward slashes "\", which I don't want
