call ToString() method auto append "

[lyx32]

JSONNode json = JSON.Parser("{\"id\":\"1\",\"name\":\"name-1\",\"data\":\"["{\"dataId\":\"1001\"}]\"}"); String val = (String)json["id"]; //return 1 String val2 = json["id"].ToString(); // return "1"

if modify code internal override void WriteToStringBuilder(StringBuilder aSB, int aIndent, int aIndentInc, JSONTextMode aMode) { //aSB.Append('\"').Append(Escape(m_Data)).Append('\"'); aSB.Append(Escape(m_Data)); }

so

String val = (String)json["data"]; // return "" String val2 = json["data"].ToString(); // return \"[\"{\"dataId\":\"1001\"}]\"

I don't quite understand the issue here. ToString of a JSONNode should return the json representation of that node. Doing an implicit or explicit cast to string will actually try to access the content only. This is the intended behaviour.

Your example code is a bit confusing since it won't compile in it's current state. Also you have quotes before your array and before your object which makes no sense unless you want to embed json text as string inside the outer json structure. However if your "data" should represent a json array there must not be a quote after the colon.

If you have trouble with some json text it might be your text that doesn't follow the right syntax.

My english is not very good, but you should be able to understand what i mean
