    "data2": "t2",
    "data3": "t3",
    "data4": "t4"

Damn guys, i can't undestand how i can use JSON Serialization with my code:( Help pls little girl:D Im a newbuy. Put please { "snippet": { "data": "t1", "data2": "t2", "data3": "t3", "data4": "t4" }, "data": { "st": "bxx" } }

var resultHttpPost = ZK.HttpPost("https://urlcom", "here is need be code with json", "application/json", "", "iso-8859-1", ZK.InterfacesLibrary.Z.Http.ResponceType.HeaderAndBody);

Q: How can I post (JSON) data? A: You can google "C# JSON", and find links like this: [JSON Serialization](https://msdn.microsoft.com/en-us/library/bb410770%28v=vs.110%29.aspx). Q: How can I post multi-line JSON data? A: The format is irrelevant. As far as the HTTP message - it doesn't matter if it's one line, or multiple lines,. — FoggyDay, Feb 14 '15 at 01:08

Why do you think you need to make the request separated by newline? It is usually just printed that way for readability. — dub stylee, Feb 14 '15 at 01:12

You've really got three separate questions here:

Q1) How can I post (JSON) data?

A: You can google "C# JSON", and find links like this: JSON Serialization.

Q2) How can I post multi-line JSON data?

A: The format is irrelevant. As far as the HTTP message - it doesn't matter if it's one line, or multiple lines. "Formatting" is a presentation issue - JSON parsers will read exactly the same message with or without formatting.

If you want to present in a "fomatted" form, then:

a) you must not send as "Content-Type: application/json". You should use "text/plain" or "html/text" instead

... and ...

b) you should use the HTML <pre> tag to preserve formatting.

Q3) How do I set "Content-Type"?

That depends entirely on what library you're using to create and send your HTTP data.

Here is one possibility:

How do you set the Content-Type header for an HttpClient request?

HttpClient c = new HttpClient();
c.BaseAddress = new Uri("http://example.com/");
c.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
...

JSON should be in single quotes and you will need "+" operator for concatenation. Your JSON should look like this.

"{"+
  "'snippet': {"+
    "'data': 't1',"+
    "'data2': 't2',"+
    "'data3': 't3',"+
    "'data4': 't4'"+
  "},"+
  "'data': {"+
    "'st': bxx'"+
  "}"+
"}";
