Detect language of string from Google API C#

i am trying to detect what language the written txt of player.LastChat is, and i am having some difficulties.

Here's the code i have: 

String[] words = player.LastChat.Trim().Split(new Char[]{' ','\t',',','.',':','!','?',';','(',')',']','[','"'});
StringBuilder edited = new StringBuilder();
// Remove exception list words from line
foreach (String w in words) {
    if (plugin.isInList(w, "good_words")) {
        continue;
    }
    edited.Append(w);
    edited.Append(" ");
}

// URL Encode edited string
String UnreservedChars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_.~";
StringBuilder Result = new StringBuilder();
String Input = edited.ToString();

for (int x = 0; x < Input.Length; ++x)
{
    if (UnreservedChars.IndexOf(Input[x]) != -1)
        Result.Append(Input[x]);
    else
        Result.Append("%").Append(String.Format("{0:X2}", (int)Input[x]));
}
String key = "API KEY";
// Test for badness
bool jsonresult = false;

try {
    WebClient client = new WebClient();
    String json = client.DownloadString("https://www.googleapis.com/language/translate/v2/detect?key=" + key + "&q=" + Result.ToString());
    jsonresult = json.Contains("en");
} catch (Exception e) {
    plugin.ConsoleWrite("Language check failed! Error: " + e);
}
if (!jsonresult) {
    return true;
}
plugin.ConsoleWrite("Language: " + jsonresult);
return jsonresult; // for Actions

So, what i am trying to achieve, is to return true if it is any other language than "en" (english), but it is returning true no matter what.

The response from google is this:

{
"data": {
"detections": [
[
{
"language": "en",
"isReliable": false,
"confidence": 0.03396887
}
]
]
}
}

Any help is much appreciated, and i have no idea how to code, this code is borrowed from another script.

Regards.

To make method work as described, you should change:

if (!jsonresult) {
    return true;
}
plugin.ConsoleWrite("Language: " + jsonresult);
return jsonresult;

to: 

plugin.ConsoleWrite("Language: " + jsonresult);
return !jsonresult;

also this line

jsonresult = json.Contains("en");

is checking for any occurance of "en" in json text (and is found in "confidence" in your json). What you should do, is to parse Json using json.net (or other lib), or simply do this (but is an ugly hack): 

jsonresult = json.Contains("\"language\": \"en\",");
