C＃JavaScriptSerializer創建無效的json

我試圖將匿名對象轉換成JSON對象，但是當我解析轉換的結果時，它說JSON無效。我無能爲力，爲什麼這樣做。任何幫助將非常感激。乾杯!C＃JavaScriptSerializer創建無效的json

var s = new 
{ 
    displayName = "ppplll", 
     description = "Self help community for library", 
     groupTypes = new[] { "Unified" }, 
     mailEnabled = true, 
     mail = "[email protected]", 
     mailNickname = "library", 
     securityEnabled = false 
}; 
JavaScriptSerializer js = new JavaScriptSerializer(); 
string json = js.Serialize(s);

時生成的JSON：

"{\"displayName\":\"ppplll\",\"description\":\"Self help community for library\",\"groupTypes\":[\"Unified\"],\"mailEnabled\":true,\"mail\":\"[email protected]\",\"mailNickname\":\"library\",\"securityEnabled\":false}"

解析如何？誰說JSON無效？什麼json被生產？ – Evk

解析它在：https://jsonformatter.curiousconcept.com/。在帖子中還包括Json。 –

因此，json是有效的。問題依然存在：誰說這是無效的？ – Evk
